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
motherlode.ucar.edu/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@163
password : same as hxfcalf@163
ncep资料各个分量下载:
aa.gov/data/p.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
aa.gov/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
v:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Global_d
4.1 格点资料定义---dds
v:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Global_d.dds
4.2 其它可使用参数(dds, das, dods, info, html,ascii)
4.3 举例:
html如何下载可以获取的运行资料日期和时次
v:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Global_d.ascii?run
可供查询的预报时刻
v:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Global_d.ascii?time
可供查询的等压面层次
v:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Global_d.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://aa.gov/pub/Datasets/ncep/
6.    String urll = "v:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Global_d.dods?Relative_humidity[0][0][0][1:180][1:359]";
