Then if multiple adjustments are required, multiply all of the normalized values together, then multiply that product by the value indicated on the power loss curve in Fig. 2. The resulting product is the final power loss based on all factors. See example no. 1.To make adjustments to the SOA curve in Fig. 3, determine your maximum PCB Temp & Case Temp at the maximum operating current of each iP1203PbF . Then, add the correction temperature from the normalized curves in Figs. 4, 5, 6 or 7 to the T X axis intercept (see procedure no. 2 above) in Fig. 3. When multiple adjustments are required, add all of the temperatures together, then add the sum to the T X axis intercept in Fig. 3. See example no. 2.Operating Conditions for the following examples:Output Current = 12A Input Voltage = 13.2V Inductor = 0.6µHOutput Voltage = 1.2VSw Freq= 400kHzExample 1) Adjusting for Maximum Power Loss:(Fig. 2)Maximum power loss = 4.1W(Fig. 4)Normalized power loss for input voltage ≈ 1.025(Fig. 5)Normalized power loss for output voltage ≈ 0.97(Fig. 6)Normalized power loss for frequency ≈ 1.08(Fig. 7)Normalized power loss for inductor value ≈ 1.08Adjusted Power Loss = 4.1 x 1.025 x 0.97 x 1.08 x 1.08 ≈ 4.75WApplying the Safe Operating Area (SOA) CurveThe SOA graph incorporates power loss and thermal resistance information in a way that allows one to solve for maximum current capability in a simplified graphical manner. It incorporates the ability to solve thermal problems where heat is drawn out through the printed circuit board and the top of the case.Procedure1)Draw a line from Case Temp axis at T CASE to the PCBTemp axis at T PCB .2)Draw a vertical line from the T X axis intercept to the SOAcurve. (see AN-1047 for further explanation of T X )3)Draw a horizontal line from the intersection of the verticalline with the SOA curve to the Y axis. The point at which the horizontal line meets the y-axis is the SOA current.4)If no top sided heatsinking is available, assume T CASEtemperature of 125°C for worst case performance.120102030405060708090100110102030405060708090100110120PCB Temperature (ºC)O u t p u t C u r r e n t (A )Case Temperature (ºC)iP1203PbFExample 2) Adjusting for SOA Temperature:Assuming T CASE = 110°C & T PCB = 90°C for both outputsOutput1(Fig. 4)Normalized SOA Temperature for input voltage ≈ +0.7°C(Fig. 5)Normalized SOA Temperature for output voltage ≈ -0.75°C (Fig. 6)Normalized SOA Temperature for frequency ≈ +1.0°C (Fig. 7)Normalized SOA Temperature for inductor value ≈ +2.0°CT X axis intercept temp adjustment = +0.5°C - 0.75°C + 1.0°C +2.0°C ≈ +2.75°CThe following example shows how the SOA current is adjusted for a T X change of +2.75°C and output is in SOAFig. 10: Power Loss Test Circuit120102030405060708090100110102030405060708090100110120PCB Temperature (ºC)O u t p u t C u r r e n t (A )Case Temperature (ºC)TXFig. 11: Recommended PCB Footprint (Top View)iP1203PbFThe operating switching frequency (f SW ) range of iP1203PbF is 200 kHz to 400 kHz. The desired fre-quency is set by placing an external resistor to the R T pin of the iP1203PbF . See Fig. 9 for the proper resistor value.The iP1203PbF is capable of accepting an external digital synchronization signal. Synchronization will be enabled by the rising edge clock. The free run-ning oscillator frequency is twice the switching fre-quency. During synchronization, R T is selected such that the free running frequency is 20% below the synchronization frequency. The maximum synchro-nization frequency that iP1203PbF can accept is 800kHz. Note that the actual switching frequency is half the synchronization frequency.iP1203PbF User s Design GuidelinesThe iP1203PbF is a single output 15A power block consisting of optimized power semiconductors, PWM control and its associated passive components. It is based on a synchronous buck topology and offers an optimized solution where space, efficiency and noise caused by parasitics are of concern. The power block operates with fixed frequency voltage mode control. The iP1203PbF components are integrated in a land grid array (LGA) package.V IN / Enabling the OutputThe input operating voltage range of the iP1203PbF is 5.5V to 13.2V.The iP1203PbF output is turned on upon application of input voltage. The V IN slew rate should not exceed 50mV/µs. The converter can also be turned on and off by releasing or pulling the SS pin low through a logic level MOSFET, the drain of which connects to the soft start pin (see Fig.12). This feature can be useful if sequencing or different start-up timing of dif-ferent system outputs are required. In situations where the output has undergone a latched shutdown due to overvoltage, cycling Vin will reset the output. Cycling soft start pin will not unlatch the output.Soft StartThe Soft Start function provides a controlled rise of the output voltage, thus limiting the inrush current.The soft start function has an internal 25µA +/-20%current source that charges the external soft start capacitor C ss up to 3V. During power-up, the output voltage starts ramping up only after the charging volt-age across the C ss capacitor has reached a 0.8Vtyp threshold, as shown in Fig. 13.Fig. 13: Power Up Threshold3V0.8VtypV Css V OUTFig.12: Soft Start/Enable CircuitFrequency and SynchronizationOvercurrent Protection HICCUPThe overcurrent protection function of the iP1203PbF offers a hiccup feature. During overloads, when the overcurrent trip threshold is reached, the power sup-ply output shuts down and attempts to restart (out-put HICCUP mode). The time duration between the shutdown of the output and the restart is determined by the time it takes to discharge the soft start ca-pacitor. Typically, the discharge time of the soft start capacitor is 10 times the charge time. The duty cycle of the hiccup process is typically 5%. The output will stay in hiccup indefinitely until the overload is re-moved. The typical overcurrent trip threshold of the device is internally set at 30A. The overcurrent shut-down / HICCUP threshold is about ±30% accurate.The iP1203PbF overcurrent shutdown and HICCUP threshold can be set externally by adding R OCSET re-sistor from OCSET pin. Refer to Fig.8 for R OCSET se-lection.Overvoltage Protection (OVP)Overvoltage is sensed through output voltage sense pin FB s . The OVP threshold is set to 115% of the output voltage. Upon overvoltage condition, the OVP forces a latched shutdown. In this mode, the upper FET turns off and the lower FET turns on, thus crowbaring the output. Reset is performed by recy-cling the input voltage. Overvoltage can be sensed by either connecting FB s to its corresponding output through a separate output voltage divider resistor network, or it can be connected directly to its corre-sponding feedback pin FB. For Type III control loop compensation, FB s should be connected through voltage dividers only.Refer to the iP1203PbF Design Procedure section on how to set the OVP trip threshold.PGOODThis is an output voltage status signal that is open collector and is pulled low when the output voltage falls below 85% of the output voltage. High state in-dicates that outputs are in regulation. The PGOOD pin can be left floating if not used.Thermal ShutdownThe iP1203PbF provides thermal shutdown. The threshold typically is set to 140°C. When the trip threshold is exceeded, thermal shutdown turns the output off. Thermal shutdown is not latched and au-tomatic restart is initiated when the sensed tempera-ture drops to the normal range.Only a few external components are required to com-plete a dual output synchronous buck power supply using iP1203PbF. The following procedure will guide the designer through the design and selection pro-cess of these external components.A typical application for the iP1203 is:V IN = 12V, V OUT = 1.5V, I OUT = 15A, f sw = 300kHz, V p-p == 50mVSetting the Output VoltageThe output voltage of the iP1203PbF is set by the 0.8V reference Vand external voltage dividers.Fig. 14: Typical Scheme for Output Voltage Setting V OUT is set according to equation (1):V OUT = V REF x (1 + R 2 /R 5 ) (see Fig. 14)(1)Setting R 2 to 1K, V OUT to 1.5V and V REF to 0.8V, will result in R 5= 1.14 Kohms. Final values can be se-lected according to the desired accuracy of the out-put.To set the output voltage for Type III compensation,refer to equation (24) in Type III compensation sec-tion.iP1203PbF Design ProcedureSetting the Overvoltage TripThe output of the iP1203 will shut down if it experi-ences a voltage in the range of 115% of V OUT . The overvoltage sense pin FB s is connected to the out-put through voltage dividers, R26 and R27 (Fig. 14),and the trip setpoint is programmed according to equation (1). A separate overvoltage sense pin FB s is provided to protect the power supply output if for some reason the main feedback loop is lost (for in-stance, loss of feedback resistors). An optional 100pF capacitor (C14) is used for delay and filtering.If this redundancy is not required and if a Type II con-trol loop compensation scheme is utilized, FB s pin can be connected to FB.Selecting the Soft-Start CapacitorThe soft start capacitor C ss is selected according to equation (2):t ss = 40 x C ss(2)where,t ss is the output voltage ramp time in milliseconds,and C ss is the soft start capacitor in µF.A 0.1µF capacitor will provide an output voltage ramp-up time of about 4ms.Input Capacitor SelectionThe switching currents impose RMS current require-ments on the input capacitors. Equation (3) allows the selection of the input capacitors.where, I out is the output current, and D is the duty cycle and is expressed as:D = V OUT / V IN .For the above example D= 0.13 and, using equation (3) the capacitor rms current yields 5.0A.For Type II compensation,(3))1(D D I I out RMS −=For better efficiency and low input ripple, select low ESR ceramic capacitors. The amount of the capaci-tors is determined based on the rms rating. In the above example, a total of 3 x 22µF, 2A capacitors will be required to support the input rms current.Output Capacitor C O SelectionSelection of the output capacitors depends on two factors:a. Low effective ESR for ripple and load transient re-quirementsTo support the load transients and to stay within a specified voltage dip ∆V due to the transients, ESR selection should satisfy equation (4):R ESR ≤ ∆V / I Loadmax(4)Where,I Loadmax is the maximum load current.If output voltage ripple is required to be maintained at specified levels then the expression in equation (5) should be used to select the output capacitors.R ESR ≤ V p-p / I ripple(5)Where,V p-p is the peak to peak output ripple voltage .I ripple is the inductor peak-to peak ripple current.In addition, the voltage ripple caused by the output capacitor needs to be significantly smaller than the ripple caused by the ESR of the capacitor. Use equa-tion (6) to satisfy this requirement.If the inductor current ripple I ripple is 30% of I OUT1, the 50mV peak to peak output voltage ripple requirement will be met if the total ESR of the output capacitors is less than 11m Ω. This will require 2 x 470µF POSCAP capacitors. Additional ceramic capacitors can be added in parallel to further reduce the ESR. Care should be given to properly compensate the control loop for low output capacitor ESR values.When selecting output capacitors, it is important to consider the overshoot performance of the power sup-ply. If the amount of capacitance is not adequate, then,when unloading the output, the magnitude of the over-shoot due to stored inductor energy, and depending on the speed of the response of the control loop, can exceed the overvoltage trip threshold of the iP1203PbF and can cause undesirable shutdown of the output. The magnitude of the overshoot should be kept below 1.125V OUT . To prevent the overshoot from tripping the output a delay can be added by in-stalling capacitor C14 as shown in Fig.14.b. StabilityThe value of the output capacitor ESR zero frequency f esr plays a major role in determining stability. f esr is calculated by the expression in equation (7).f ESR = 1 / (2 π x R ESR x C O )(7)Details on how to consider this parameter to design for stability are outlined in the control loop compen-sation section of this datasheet.Inductor L O SelectionInductor selection is based on trade-offs between size and efficiency. Low inductor values result in smaller sizes, but can cause large ripple currents and lower efficiency. Low inductor values also benefit the tran-sient performance.The inductor L o is selected according to equation (8):L O = V out x (1 - D) / (f sw x I ripple )(8)For the above example, and for I ripple of 30% of I OUT , L O is calculated to be 1.0µH.The core must be selected according to the peak of maximum output current.(6)ESRs o R f C ××>π210Control Loop CompensationThe iP1203PbF feedback control is based on single loop voltage mode control principle.The goal in the design of the compensator is to achieve the highest unity gain (0 db) crossover fre-quency with sufficient phase margin for the closed loop transfer function. The LC filter of the power sup-ply introduces a double pole with 40db/dec slope and 180° phase lag. The 180° phase contribution from the LC filter is the source of instabilty.The resonant frequency of the LC filter is expressed by equation (9):(9)The error amplifier of the iP1203PbF PWM controlleris transconductance amplifier, and its output is avail-able for external compensation.Two types of compensators are studied in this sec-tion. The first one is called Type II and it is used to compensate systems the ESR frequency f esr (equa-tion 7) of which is in the midfrequency range and Type III that can be used for any type of output capacitors and have a wide range of f esr .For output voltage settings less than 1.0V that use low ESR ceramic capacitors, it is recommended that the unity gain crossover frequency be set around 20kHz to maintain stable operation.where, g m is the transconductance of the error am-plifier.(12)Follow the steps below to determine the feedback loop compensation component values:1.

Calculate C 9 using equations (12) and (14)Calculation of the compensation components based on the example above, yields:f LC = 5.0kHz f z = 3.8kHzf 0 = 45kHz (15% of 300kHz)f esr = 14kHz, per equation (7) using R esr = 12m Ω.R 19 = 2.49K C 9 = 18nFSometimes, a pole f p2 is added at half the switching frequency to filter the switching noise. This is done by adding a capacitor C opt in Fig.15 from the output of the error amplifier (CC pin of iP1203PbF) to ground.This pole is given by equation (15):C opt is found from equation (16) by rearranging the terms in equation (15) and by setting f p2 = f sw / 2:(16)Fig. 16: Typical Type III Compensation and its Gain PlotType IIIThe Type III compensation scheme allows the use of any type of capacitors with ESR frequency of any range. This scheme suggests a double pole double zero compensation and requires more components around the error amplifier to achieve the desired gain and phase margins. Fig. 13 represents the Type III compensation network for iP1203PbF.The transfer function of the Type III compensator is given by equation (17)2.

Output Voltage Turns Off When Voltage at FB s Pin Exceeds 15% of FB (0.8V)For stable and noise free operation of the whole power system, it is recommended that the design-ers use the following guidelines:1. Follow the layout scheme presented in Fig. 23. Make sure that the output inductor L is placed as close to iP1203PbF as possible to prevent noise propagation that can be caused by switching of power at the switching node Vsw, to sensitive cir-cuits.2. Provide a mid-layer solid ground plane with con-nections to the top layer through vias. The PGND pads of iP1203PbF also need to be connected to the same ground plane through vias.3. To increase power supply noise immunity, place input and output capacitors close to one another, as shown in the layout diagram. This will provide short high current paths that are essential at the ground terminals.4. Although there is a certain degree of VIN bypass-ing inside the iP1203PbF, the external input decoupling capacitors should be as close to the device as pos-sible.5. The feedback track from the output VOUTto FB should be routed as far away from noise generating traces as possible.6. The compensation components and the Vref by-pass capacitor should be placed as close as pos-sible to their corresponding iP1203PbF pins, away from noise generating traces.7. Refer to IR application note AN-1029 (Optimizinga PCB Layout for an iPOWIR Technology Design) to determine what size vias and copper weight and thickness to use when designing the PCB.8.

MODIS Land Cover Dynamics (MCD12Q2) 产品用户手册说明书

User Guide to Collection6.1MODIS Land Cover Dynamics(MCD12Q2)ProductJosh Gray,Damien Sulla-Menashe,and Mark A FriedlMarch14,2022The Collection6.1(C6.1)MODIS Land Cover Dynamics Product(MCD12Q2)provides science data sets (SDSs)that map global land surface phenology metrics(hereafter:“phenometrics”)at500meter spatial resolution and annual time step.Phenometrics are derived from time series of MODIS observed land surface greenness,specifically:time series of the2-band Enhanced Vegetation Index calculated from MODIS nadir BRDF adjusted surface reflectances(NBAR-EVI2).This user guide provides the following information related to the C6.1product:1.An overview of the MCD12Q2algorithm2.Important differences from the C5product3.Guidance on data portals,projections,and formats,to help users access and use the data.4.Contact information for users with questions that cannot be addressed through information or websitesprovided in this document.5.A table describing the different data sets and associated scaling and fill values.C6.1provides a minor update to C6that resolves one main issue in the C6product.Specifically,in C6.1,a fix was implemented to resolve spuriously early detection of greenup dates in a small proportion of pixels caused by a discontinuity in vegetation index time series across calendar years arising from the way that splines are fit to the data(see Section2.1).In addition,the processing pipeline was adjusted to allow product generation6months after the end of the calendar year,instead of12months,which allows the product to be generated in a more timely fashion.1Product OverviewThe MODIS C6.1MCD12Q2Land Surface Dynamics Product provides global maps of phenometrics at 500m and an annual time step since2001.The product contains25SDS(REF TABLE)that record the timing of phenometrics such as the onset of greenness increase,peak greenness,senesence,and dormancy; derivative features of the vegetation cycles such as the NBAR-EVI2amplitude,NBAR-EVI2minimum,and the integrated NBAR-EVI2over a vegetation cycle;as well as the total number of vegetation cycles detected for the product year,and overall and phenometric-specific QA/QC rmation is provided for up to two detected vegetation cycles to record multicropping,precipitation-driven greenup events,and other phenological regimes that deviate from the common single annual greenup/greendown event pattern.1.1Differences from Collection5ProductThe C6.1methodological approach and SDSs differ substantially from the previous C5product.Changes were designed to better capture phenometrics in systems with multiple vegetation cycles per year,to increase the reliability of retrieved phenometrics in tropical,arid,and semi-arid ecosystems,to more accurately represent phenometrics in systems where NBAR-EVI2time series do not closely resemble logistic growth patterns,to provide working QA/QC SDS,and to deliver phenometrics in a more usable and intuitive fashion when vegetation cycles cross calendar boundaries,especially in the Southern ers of C5products should note the additional SDS,the provision of overall and bit-packed,phenometric-specific QA/QC SDSs,the change to a days since1-1-1970standard for date delivery,and the adoption of a new standard for assigning vegetation cycles to product years:all phenometrics are delivered for vegetation cycles where the date of peak NBAR-EVI2is within the product’s calendar year.This particular change should ease difficulties in collating phenometrics across product years when vegetation cycles cross calendar year boundaries by ensuring that all phenometrics for a vegetation cycle are fully contained in a single product year.2MethodologyThe C6.1MCD12Q2product is created by assembling time series of NBAR-EVI2,eliminating outliers and filling dormant period values,fitting a QA/QC-weighted penalized cubic smoothing spline to the time series, identifying valid vegetation cycles within the time series,and then extracting and recording phenometrics for each vegetation cycle.All subsequent functions are applied to a time series of three consecutive years: the product year and preceding and subsequent years.2.1Spline FitNBAR-EVI2observations identified as being snow contaminated by the MCD432product,or where the corresponding NBAR-NDSI>−0.2,are filled with a dormant period value.The dormant NBAR-EVI2is taken to be the5th percentile snow-free value across the product year and its preceding and subsequent year,unless this differs by more than25%from the10th percentile snow-free value for the central year,in which case only the central year’s data are used to compute the background NBAR-EVI2value.This is to accommodate land cover changes that may alter the true dormant period NBAR-EVI2value.Missing NBAR-EVI2values between snow-contaminated observations are also filled with the dormant NBAR-EVI2 value.Finally,a penalized cubic smoothing spline is fit to the value with the weights proportional to the MCD43A2QA/QC flags.2.2Identifying Valid Vegetation CyclesValid vegetation phases in the time series are identified as periods of sustained increase in NBAR-EVI2 followed by sustained periods of decrease,subject to ecologically meaningful heuristics concerning the length of these periods and magnitude of the NBAR-EVI2amplitude.First,“peaks”in the NBAR-EVI2time seres are identified as points where the first derivative(numerically evaluated)changes sign(Fig.1A).These candidate peaks are sorted by NBAR-EVI2magnitude and then analyzed with a recursive function that attempts to identify associated start and end dates for the greenup/down segment.Figure1:Three years of a hypothetical splined NBAR-EVI2time series with potential peaks(upper-case letters),troughs(lower-case letters),and search windows for start/end of the segment corresponding to peak F marked(A).Diagram of phenometrics retrieved for a single hypothetical vegetation cycle(B).Illustration of the methodology used to determine the phenometric-specific QA/QC score(C).Starting with the smallest peak,the start of the greenup segment is sought as the date of the minimum NBAR-EVI2value closest to the candidate peak between30days prior to peak and the maximum of:the start of the time series,the closest of any preceding candidate peaks,or the candidate peak date minus a maximum greenup period length parameter(185days).This search windows are depicted in Fig.1A for the segment associated with peak F.If the NBAR-EVI2amplitude between this minimum value and the peak is greater than or equal to0.1,and greater than or equal to35%of the time series maximum NBAR-EVI2 minus the minimum NBAR-EVI2,then the identified greenup period is considered valid and an associated greendown period is sought.If these conditions are not met,then the candidate peak is removed from the list of candidate peaks.The end of the greendown period is sought in an identical manner,but in the opposite temporal direction.A candidate end date is identified as the date of the closest minimum NBAR-EVI2 value between30days after the candidate peak and the minimum of:the end of the time series,the closest of any following peaks,or the candidate peak date plus a maximum greendown length parameter(set to 185days;Fig.1A).The entire greenup and greendown segment is considered a valid vegetation cycle ifthe NBAR-EVI2amplitude between the candidate segment end date and candidate peak is greater than orequal to0.1.Otherwise,the candidate peak is eliminated.This process is repeated,each time updating the candidate peak list,until all candidate peaks are either eliminated or identified as belonging to a valid vegetation cycle.The full3-year time series is thus partitioned into valid vegetation cycles.For example,in Fig.1A,the potential peaks would first be sorted by NBAR-EVI2magnitude:D,C,A, G,F,H,E,and B.A segment start for potential peak D would be identified as trough d and the NBAR-EVI2 amplitude between points d and D calculated.Because this amplitude is less than the global minimum of0.1,peak D would be eliminated from the list of potential peaks.Similarly,the segment associated with peakC would be eliminated because although the NBAR-EVI2magnitude between points c and C exceeds0.1, it is less than35%of the maximum NBAR-EVI2variation exhibited over the three-year interval(minimum point d and maximum point B depict an amplitude of0.67,so the35%threshold is0.234,but c to C is0.2). Likewise,the potential segment associated with peak A would be eliminated because while the NBAR-EVI2 amplitude between a and A exceeds0.1and the35%threshold,the greendown portion(points A to b)does not.The segment start/end search windows shown in Fig.1A are for the segment associated with peak F.A segment start is sought as a NBAR-EVI2minimum point between the preceding peak E and30days prior to F.The segment end date is sought between a period30days after F and the next valid peak(G).Valid vegetation cycles would be retrieved for the segments associated with peaks B,E,F,G,and H.2.3Phenometric ExtractionIdentification of phenophase transition dates is performed on each of the identified vegetation cycles for which the peak date falls within the calendar year of the product year(e.g.phenometrics associated with peak F in Fig.1A would be delivered with product year2004).The first metric:number of vegetation cycles, is determined by simply counting the number of such peaks.Subsequent phenophase date retrieval,and quantification of associated QA,are performed only for up to two of the valid segments with highest segment NBAR-EVI2amplitude.That is,if there are three cycles,the number of vegetation cycles metric will reflect the correct number,but phenophase transitions will not be retrieved for the cycle with the lowest NBAR-EVI2amplitude(e.g.product year2004for the time series represented in Fig.1A would have3for number of cycles,but only phenometrics for segments associated with peaks F and H would be delivered).The start of greenup,greenup midpoint,and maturity dates are retrieved as the first date within the greenup segment where the NBAR-EVI2time series crosses15,50,and90%of the greenup segment NBAR-EVI2amplitude (peak NBAR-EVI2-segment start EVI;Fig.1B).Similarly,start of senescence,senescence midpoint,and dormancy are retrieved as the last date within the greendown segment where the NBAR-EVI2time series crosses90,50,and15%of the greendown segment NBAR-EVI2amplitude(peak NBAR-EVI2-segment end NBAR-EVI2;Fig.1B).All dates are converted to UNIX-epoch time:days since Jan1,1970.Segment integrated NBAR-EVI2is calculated as the sum of daily NBAR-EVI2values,minus the greenup segment minimum value,between the segment start and end dates(not from the start of greenup and dormancy;Fig. 1B).NBAR-EVI2amplitude and NBAR-EVI2minimum values are also recorded as distinct product layers (NBAR-EVI2maximum can be retrieved as NBAR-EVI2amplitude-NBAR-EVI2minimum).Quality assurance(QA)scores are calculated for each phenometric(detailed QA),and for the entire greenup/down segment(overall QA).These scores are a weighted combination of the fraction of not missing (e.g.due to snow)and not filled(e.g.with dormant NBAR-EVI2value)values(80%weight),and the spline goodness-of-fit(R2;20%weight),in the vicinity of each phenometric(2weeks before and after;detailed QA;Fig.1C)or within the entire segment(overall QA).These0–1scores are mapped to categories as:[1, 0.75)=0(best),[0.75,0.5)=1(good),[0.5,0.25)=2(fair),and[0.25,0]=3(poor).Detailed QA scores are thenbit-packed into a single16-bit integer value,whereas the overall QA score is retained as a separate product layer(details on detailed QA below).3Data Formats and ProjectionMCD12Q2data are provided as tiles that are approximately10◦x10◦at

Search.3.2Known Issues and Sources of Uncertainty•Greenup and Dormancy phenometrics are anomalously early/late in some high-latitude regions with low-amplitude NBAR-EVI2variation.This likely results from the splining approach assuming a dor-mant period NBAR-EVI2value that is too low.The cause and a fix are being investigated,but until a fix is devised,users are encouraged to use the more realistic and stable MidGreenup and MidGreendown metrics to capture season start/end in these regions(e.g.high-latitude evergreen forests).•In some semi-arid and arid environments exhibiting low-amplitude NBAR-EVI2variation,there are large differences in filled pixels between the Collection5and Collection6products.Collection6 typically retrieves fewer pixels because it applies a global minimum NBAR-EVI2amplitude requirement of0.1in addition to the relative amplitude requirements in Collection5(valid segments must have NBAR-EVI2amplitude that is at least35%of the3-year max-min.)•For pixels with more than two valid vegetation cycles,the two cycles that are documented in the product may not be temporally adjacent.Instead,they are the two cycles with the largest NBAR-EVI2amplitudes.That is,the two cycles may have a temporally intervening cycle of lower amplitude.•Because heterogeneous land cover/use results in NBAR-EVI2time series that are a mixture of perhaps distinct phenologies,users should be careful in interpreting multi-cycle results.They are not,for example,guaranteed to represent two distinct cropping cycles,but may instead capture two different sub-pixel scale fields with very different sow/harvest dates.•Users may notice substantial differences in patterns of missing data between Collections5and6in the Southern Hemisphere.This is mostly a result of the difference in methodology whereby phenometrics are assigned to particular product years.Collection5phenometrics are delivered with the product year associated with the year of the particular phenometric,and so the phenometrics associated witha particular vegetation cycle may be spread across multiple product years.In Collection6,the pheno-metrics for a particular cycle are always kept together,and delivered with the product year associated with the calendar year in which the Peak phenometric falls.4Contact InformationUser Contact:•Josh Gray(****************)•Mark
