user_datm.streams[...] causes datm.input_data_list being empty

[schulzm6@staff_uni-marburg_de]

Dear all, I am trying to run the CLM 4.0 (as included in CESM 1.2.0) with my own atmospheric forcing. Therefore, I copied the datm.streams.txt[...] files from /caseDir/CaseDocs into my caseFolder, changed their name to user_datm.streams.txt[...] and modified those files in order to link to my atmospheric forcing files. When I run preview_namelist, the resulting datm.input_data_list is, however, empty. The same happens if I do not modify the user_datm.streams.txt[...] files after copying and renaming. So this is not caused by an error in my changes in the user_datm.streams.txt[...] files. Google brought me here: https://github.com/ESMCI/cime/issues/916 . The bug in CIME described here sounds similar to my problem. Anyway, I do not know whether it is actually the same problem and if it is somehow possible to use the fixes from the CIME GitHub repository for CLM. Any thoughts or solutions? Best,  Martin

./create_newcase --case HistClm50BgcCrop --res f09_g16 --compset IHistClm50BgcCrop --mach myintel --compiler intel --run-unsupported

I created this case, I want the model to use my own file download of co2 (cmip6 download rcp2.6 data)
/home/hlh/cesm/inputdata/atm/datm7/CO2/fgco2_Oyr_CanESM5_rcp26 - cmip5_r1i1p1f1_gn_2006 - 2100.nc

1. I changed it in the run_run.xml file:
<entry id="DATM_CO2_TSERIES" value="none">
<type>char</type>
<valid_values>none,20tr,20tr.latbnd,rcp2.6,rcp4.5,rcp6.0,rcp8.5</valid_values>
<desc>DATM CO2 time series</desc>
</entry>

2. I changed it in the run_run.xml file:
<entry id="DATM_CLMNCEP_YR_START" value="2006">
<type>integer</type>
<desc>starting year to loop data over</desc>
</entry>
<entry id="DATM_CLMNCEP_YR_END" value="2100">
<type>integer</type>
<desc>ending year to loop data over</desc>
</entry>

3. I changed it in the run_run.xml file:
<entry id="CLM_CO2_TYPE" value="diagnostic">
<type>char</type>
<valid_values>constant,diagnostic,prognostic</valid_values>

4. I added to the user_nl_datm file:
co2_type = 'diagnostic'
fgco2_file = '/home/hlh/cesm/inputdata/atm/datm7/CO2/fgco2_Oyr_CanESM5_rcp26-cmip6_r1i1p1f1_gn_2006-2100.nc'
/

But an error is reported:
hlh@hlh-desktop:~/clm5.0/cime/scripts/my_custom_co2_case$ ./case.build --skip-provenance-check
Building case in directory /home/hlh/clm5.0/cime/scripts/my_custom_co2_case

ERROR: Variable 'fgco2_file' from file '/home/hlh/clm5.0/cime/scripts/my_custom_co2_case/Buildconf/datmconf/namelist_infile' is not in the namelist definition.


I found that errors occurred when I added contents in the user_nl_datm file and the user_nl_clm file

How do I get the model to use my CO2 data

Thanks for your answer

One solution to this is posted here:
