prepare geo_em file for Noah-MP MMF groundwater and crop scheme simulation

[cenlinhe]

Response from an email chain answering users' question about creating geo_em file for Noah-MP MMF groundwater scheme simulation:

you need to link GEOGRID.TBL.ARW.noamp to use additional parameters (related to groundwater and crop) in WPS geogrid. There isn't a documentation for this procedure, but some information are scattered around the WRF forum and WPS update page:
https://forum.mmm.ucar.edu/threads/difference-between-geogrid-tbl-arw-and-geogrid-tbl-noahmp.259/
https://www2.mmm.ucar.edu/wrf/users/wps_files/wpsv3.9/updates-3.9.html

To use this table in WRF v3.9 and later, you would need to link GEOGRID.TBL.ARW.noamp with the default table in the WPS/geogrid/ directory:

ln -sf GEOGRID.TBL.ARW.noamp GEOGRID.TBL

Then run ./geogrid.exe will give you these additional parameters in geo_em.d01.nc.
You can read these parameter information in GEOGRID.TBL.ARW.noamp.
