如何下载ncep资料

ncep资料下载

1. 8天预报。（含0小时）3小时间隔1x1 deg gfs(globle forecast model)每个文件大约1g /cgi-bin/ldm/genweb?native/grid/NCEP/GFS/Global_onedeg

2. 再分析。1 x 1deg 再分析历史记录可以通过如下站点下载：

NCEP FNL Global Tropospheric Analyses, 1x1, daily 1999Jul30- present

user : hxfcalf@

password : same as hxfcalf@

ncep资料各个分量下载：

/data/gridded/data.ncep.reanalysis.html

3. 一个时次预报。拆散的1x1 deg gfs(globle forecast model)每个文件大约15m

/pub/gfs/rotating-grb2/

4.可以通过OPENDAP获取指定预报时次、区域、类型、层次的格点场

:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Glo bal_onedeg_fmrc.ncd

4.1 格点资料定义---dds

:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Glo bal_onedeg_fmrc.ncd.dds

4.2 其它可使用参数（dds，das，dods，info，html，ascii）

4.3 举例：

可以获取的运行资料日期和时次

:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Glo bal_onedeg_fmrc.ncd.ascii?run

可供查询的预报时刻

:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Glo bal_onedeg_fmrc.ncd.ascii?time

可供查询的等压面层次

:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Glo bal_onedeg_fmrc.ncd.ascii?pressure

其它可使用参数：（run，time，pressure，pressure2 ,lat，lon，depth_below_surface_layer）pressure=26的物理量：(ascii?pressure[0:25])

Geopotential_height,Temperature,U-component_of_wind,V-component_of_wind,

Absolute_vorticity

pressure2 = 21的物理量

Float32 Relative_humidity[run = 12][time = 61][pressure2 = 21][lat = 181][lon = 360];

Cloud_mixing_ratio, Vertical_velocity_pressure

5. *.nc格式的单要素/年动态历史库。ftp:///pub/Datasets/ncep/

6. String urll = ":8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Glo bal_onedeg_fmrc.ncd.dods?Relative_humidity[0][0][0][1:180][1:359]";
