(shr_ncread_domain) ERROR: var does not exist (lon), (Error in DATA sizes)

[AquaTech_007]

Hi,

I am running CLM5 and trying to prescribe the soil moisture data by using the soil moisture stream in user_nl_clm (given below) and i am getting this error (ERROR: (shr_ncread_domain) ERROR var does not exist lon) and invalid dimension ID. There is might be problem with the soil moisture NetCDF. All the variables are mentioned in the nc file. I have prepared the soil moisture nc file according to the meteorological forcing data nc file. The input meteorological data is hourly so i have also used the soil moisture data hourly with 20 soil layers for the three years.

I am attaching the cesm log document and soil moisture NetCDF google drive link because of the size restriction not able to upload it here( PrescribeSM.nc ) with this thread. If anyone can provide the insight, thank you in advance.

use_soil_moisture_streams = .true.
&soil_moisture_streams
stream_year_first_soilm = 2021
stream_year_last_soilm = 2023
model_year_align_soilm = 2021
soilm_tintalgo = 'linear'
soilm_offset = 0
soilm_ignore_data_if_missing = .true.
stream_fldfilename_soilm = '/home/hydrology/simulations/prescribe_data/PrescribeSM.nc'

@AquaTech_007 you are probably correct that something is wrong with the netcdf file. The error message does not give enough information for me to help you, so you will need to troubleshoot. I searched the forums for "soil stream" and found examples where users used the same model functionality and had to troubleshoot:

Changed soil moisture boundary condition, case build failed

What version of the code are you using? - CESM 2.1.5 Have you made any changes to files in the source tree? - To change soil moisture boundary condition I added the following line in the /glade/u/home/maruf/my_cesm_sandbox_v6/components/clm/bld/namelist_files: Full pathname of soil moisture...

Thank you @slevis for the references. It helped alot.

The issue has been resolved. The NetCDF file requires the dimensions for the soil moisture data to be in the order of (lon, lat, time, nlevsoi). I tested it with data for 10 soil layers, and it worked.

Can you please help change the thread title or tell me how to do it? I have written a name by chance it should be, ((shr_ncread_domain) ERROR: var does not exist (lon)) or "(Error in DATA sizes)." It would be helpful if the title could be updated so others in the community with same issue can find it.
