运行wrfcamx的过程中,显示:
WRF landuse is: USGS
Number of landuse categories: 24
Using dominant landuse fields
Cannot find surface roughness in the WRF file
Using defaults for USGS, NLCD or IGBP landuse
error in 3d_var_real read, dimension problem
33 33
33 33
28 27
13 43
error stop
是什么原因?WRF默认的土地利用数据USGS不行吗
