FNL and soil levels

Post by andres » Thu Jun 28, 2018 5:32 pm

I am using local FNL data for a run. First step is

ems_prep --dset fnl --analysis --local --cycle 00 --date 20180317 --domains 4 --length 216

which seems to work. interestingly in wrfprd only the 1st met_em is created for the subdomains, which might be a problem

-rw-r--r-- 1 wrf wrf 78M jun 28 13:17 met_em.d01.2018-03-17_00:00:00.nc
-rw-r--r-- 1 wrf wrf 78M jun 28 13:17 met_em.d01.2018-03-17_06:00:00.nc
...
...
-rw-r--r-- 1 wrf wrf 78M jun 28 13:18 met_em.d01.2018-03-26_00:00:00.nc
-rw-r--r-- 1 wrf wrf 32M jun 28 13:18 met_em.d02.2018-03-17_00:00:00.nc
-rw-r--r-- 1 wrf wrf 32M jun 28 13:18 met_em.d03.2018-03-17_00:00:00.nc
-rw-r--r-- 1 wrf wrf 32M jun 28 13:18 met_em.d04.2018-03-17_00:00:00.nc

The problem comes in the next step

ems_run --dset fnl --noscour --cycle 00 --local --date 20180317 --domains 4 --length 216

which gives

Unable to determine number of soil levels in met_em.d01.2018-03-17_00:00:00.nc.

and in fact, the namelist.wrfm has

num_metgrid_soil_levels = 4

but

if I explore the geo_em data with

ncdump -h wpsprd/met_em.d01.2018-03-17_00\:00\:00.nc | grep SOIL | less

the global attributes describe

:NUM_METGRID_SOIL_LEVELS = 0 ;

Any clue of what is missing?

Hi Andres - where did you download the updated .FNL file? I've been having trouble getting land surface models to work.

Thank You!
