NOAHMP questions

[William.Hatheway]

I have a few questions about NOAHMP

1. Do you have to change the geogrid file link from geogrid.arw to geogrid.arw.noahmp to use noahmp?
2. Which optional or supplementary files are needed to use noahmp for geography
3. If you don't call the noahmp geogrid file and you put the noahmp commands in namelist.input does WRF ignore them |
such as the commands below

&noah_mp
dveg                     = 4,     
opt_crs                  = 1, 
opt_sfc                  = 1
opt_btr                  = 2,
opt_run                  = 3,
opt_frz                  = 1,
opt_inf                  = 1,
opt_rad                  = 3,
opt_alb                  = 2,
opt_snf                  = 4,
opt_tbot                 = 1,
opt_stc                  = 3,
opt_gla                  = 1,
opt_rsf                  = 1,
/

4. What are the benefits of using noahmp vs noah?

Please see my answers below:

1. Do you have to change the geogrid file link from geogrid.arw to geogrid.arw.noahmp to use noahmp?

Yes you must switch to geogrid.arw.noahmp if you run WRF with NoahMP option

2. Which optional or supplementary files are needed to use noahmp for geography

All those files contained under 'CROP' and 'soilgrids', for example planting, harvest, croptype, etc., are extra files required for running NoahMP.

3. If you don't call the noahmp geogrid file and you put the noahmp commands in namelist.input does WRF ignore them

This usually (not always) will cause problems later when running wrf.exe. We won't recommend doing so.
