关于geog_data_res中值的选择？

清晨的雨

geog_data_res中有10m、5m、2m、30s，在模式中有什么原则或者规律来分别选择哪个数据？请各位专家指教，谢谢！

“Possible available resolutions are 10m (~19km), 5m (~9km), 2m (~4km), and 30s (~0.9km).

When there are multiple resolutions available for geographical input data, choose a resolution that is slightly better than your grid resolution. For example, if your grid resolution is 9km, using 2 minute static data would be ideal”                                                                                                  ——引自楼上
总结如下：10m (~19km), 5m (~9km), 2m (~4km), and 30s (~0.9km) （这里的m、s说的是分和秒，换算就是一度为60分，1分为60秒，后面的是约等为距离，单位km）,地形数据的分辨率最好稍微高于网格数据的分辨率。

Resolution of source data to be used when interpolating static terrestrial data.

Beginning with V3.8, the default datasets to produce the HGT_M, GREENFRAC, and LU_INDEX/LANDUSEF fields were changed. Detailed information about this can be found in the namelist.wps file that is included in the WPSV3.8 tar file.

If you wish to use USGS static terrestrial data, instead of the default MODIS data, you would need to specify geog_data_res to:

geog_data_res = 'usgs_30s+default', 'usgs_30s+default',

Prior to V3.8, USGS was the default. If you are using a version of WPS that is prior to V3.8, and you wish to use the default USGS data, then it is only necessary to specify:

geog_data_res = '10m', '2m', '30s'

Prior to V3.8, if you wish to use the MODIS data, it would be necessary to specify:

geog_data_res = 'modis_30s+10m', 'modis_30s+2m', 'modis_30s+30s'

Possible available resolutions are 10m (~19km), 5m (~9km), 2m (~4km), and 30s (~0.9km).

When there are multiple resolutions available for geographical input data, choose a resolution that is slightly better than your grid resolution. For example, if your grid resolution is 9km, using 2 minute static data would be ideal

看看数值计算的书吧

如果你不想答呢，可以不答，说着不疼不痒毫无用处的话，什么意思》？
