Mismatch between namelist and wrf input files for dimension NUM_LAND_CAT

[dmantsis1976]

Hi

I am trying to incorporate the CORINE land use map into my WRF runs and I encountered a problem. I am getting an error

----------------- ERROR -------------------
namelist : NUM_LAND_CAT = 44
input files : NUM_LAND_CAT = 45 (from geogrid selections).
d01 2022-07-01_00:00:00 ---- ERROR: Mismatch between namelist and wrf input files for dimension NUM_LAND_CAT
NOTE: 1 namelist vs input data inconsistencies found.

after looking at the geo_em.d01.nc file the d01 domain has values from 1-44. There is no 45 value. So I don't understand why this takes place. I know there is a previous post with the same title (responding to that post has been disabled), and is addressing the same issue. However, this problem occurred when running real.exe not wrf.exe. I was wondering if anyone could help me figure out why this takes place. I think something happens during the conversion of the geotiff CORINE map into geogfid format, but I am not sure why.

Thank you

Please type the command:
ncdump -h geo_em.d01.nc | grep -i NUM_LAND_CAT, what value can you get?

Similarly, what value is it in your met_em and wrfinput files?

Dear Dr Chen
I get 45 for both geo_em and met_em files. The wrfinput files are not generated because real.exe fails when I try to run it. I looked in the geo_em files and the range is 1-44, there is no 45 value. The conflict is with the num_land_cat=44 that I have in my namelist.input (by the way this is the correct value). Someone told me that this problem is due to the GeoTiff-->Geogrid conversion (this is done using convert_geotiff command that I got from GitHub; this is what everyone is using). Let me know if you have any suggestions.

I was wondering if WRF allows the use of different land use data (with different number of classes) for different domains. I would be interested in this option if there is no other way to solve the problem.

Thank you for your time
