PFILE
WARNING: Couldn’t open file PFILE:2018-06-30_00 for input.
ERROR: The mandatory field TT was not found in any input data.
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 0
修改方法：
打开namelist.wps：
改为
&ungrib
out_format = ‘WPS’
prefix = ‘FILE’
/
&metgrid
fg_name = ‘FILE’
io_form_metgrid = 2
opt_metgrid_tbl_path = ‘./metgrid’
/
即该PFILE为FILE，即可完成
