运行real.exe时出现NUM_METGRID_SOIL_LEVELS=0

 本人在运行real.exe时，发现出现这样的报错：

d01 2020-01-01_00:00:00 ---- ERROR: Mismatch between namelist and global attribute NUM_METGRID_SOIL_LEVELS
NOTE:       2 namelist vs input data inconsistencies found.
-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE:    LINE:    1299

application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
[unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=1
:
system msg for write_line failure : Bad file descriptor

在别的地方运用同样数据并设置相同的namelist.wps运行得到的NUM_METGRID_SOIL_LEVELS=4，而在此处得到的NUM_METGRID_SOIL_LEVELS=0。找了很多可能原因，最终找到解决方式，参考此网址：Problem in metgrid? Running real.exe throws error NUM_METGRID_SOIL_LEVELS must be greater than 1 | WRF & MPAS-A Support Forum

问题出现在了ERA5数据集上面，建议重新下载再运行。
