WRF中如何使用SRTM的3s高分辨率地形数据集
WRF中地形数据（海拔高度）分辨率最高为30s，差不多就是900m，当模型空间分辨率较高时，比如在低于1km的情况下，经常会考虑增加地形高度的分辨率，这里使用美国的SRTM（ Shuttle Radar Topography 转为geogrid二进制格式 cd DEM/Yunnan/ convert_geotiff -w 4 -t 1500 -u "meters MSL" -d "3s topography" -b 0 -m -32768 Yunnan.tif 其中-w 4表示用4个字节来存储单个整数，-t 1500表示输出单个瓦片文件的长度和宽度，-u "meters MSL"表示单位，-d "3s topography 8.333334e-04 dy = 8.333334e-04 type = continuous signed = yes units = "meters MSL" description = "3s topography
