http://nomad3.ncep./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
http://thredds.:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Global_onedeg_fmrc.ncd 4.1 格点资料定义---dds
http://thredds.:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Global_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
http://thredds.:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Global_onedeg_fmrc.ncd.ascii?run 可供查询的预报时刻
http://thredds.:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Global_onedeg_fmrc.ncd.ascii?time 可供查询的等压面层次
http://thredds.:8080/thredds/dodsC/fmrc/NCEP/GFS/Global_onedeg/NCEP-GFS-Global_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。
