num_metgrid_levels

[leila mahmoudi]

hello

my outputs from WPS don't show num_metgrid_levels
and WRF gives error about mismatch between WPS namelist and input namelist in WRF section as below:

DYNAMICS OPTION: Eulerian Mass Coordinate
alloc_space_field: domain 1 , 748731348 bytes allocated
d01 2021-01-01_00:00:00 Yes, this special data is acceptable to use: OUTPUT FROM METGRID V4.1

d01 2021-01-01_00:00:00 ---- ERROR: Mismatch between namelist and input file dimensions
NOTE: 1 namelist vs input data inconsistencies found.


I ran this simulation by using ERA5 reanalysis data.
I have downloaded wind components data (w, 10u, 10v) and temperature data (2t).
I didn't download any other parameters. can it be reason?
I have installed WRF recently. Does it also cause error?

I'm looking for your kind help.

Hi,
It looks like you only have a single level of data in your input files. You will need to download the surface and 3d atmospheric data. Take a look at this list of required fields.

dear Ms kwerner
thank you for your reply.
I figured it out and I downloaded all surface data (SFC) and pressure level data (PL) data.

I'm glad you were able to get past the problem. Thanks for the update!
