CAM 5 File Path

[hsalah]

Hello,
I have an issue with rad_diag_2 ,ncdata and &rad_cnst_nl; it is at a default file path and I am unable to change it to my file path because I do not have the data.

I have copied my terminal screen:

ncdata = '/scratch/geo/unger/yh463/EMISSION/CAM5_SD/fgeos.e12_rel07_chem.FSDSMAM.f19.f19.relv1.cam.i.2006.1x_56L.nc'


rad_diag_1 = 'A:Q:H2O', 'N:O2:O2',


'A:CO2:CO2', 'A:O3:O3',


'A:N2O:N2O', 'A:CH4:CH4',


'A:CFC11:CFC11', 'A:CFC12:CFC12'


rad_diag_2 = 'A:Q:H2O', 'N:O2:O2',


'A:CO2:CO2', 'A:O3:O3',


'A:N2O:N2O', 'A:CH4:CH4',


'A:CFC11:CFC11', 'A:CFC12:CFC12',


'M:mam3_mode1_noBC:/scratch/geo/fedorov/bpd6/Data/CESM/1.0/inputdata/atm/cam/physprops/mam3_mode1_rrtmg_c110318.nc',


'M:mam3_mode2:/scratch/geo/fedorov/bpd6/Data/CESM/1.0/inputdata/atm/cam/physprops/mam3_mode2_rrtmg_c110318.nc',


'M:mam3_mode3:/scratch/geo/fedorov/bpd6/Data/CESM/1.0/inputdata/atm/cam/physprops/mam3_mode3_rrtmg_c110318.nc'


rad_diag_3 = 'A:Q:H2O', 'N:O2:O2',


'A:CO2:CO2', 'A:O3:O3',


'A:N2O:N2O', 'A:CH4:CH4',


'A:CFC11:CFC11', 'A:CFC12:CFC12',


'M:mam3_mode1_noPOM:/scratch/geo/fedorov/bpd6/Data/CESM/1.0/inputdata/atm/cam/physprops/mam3_mode1_rrtmg_c110318.nc',


'M:mam3_mode2:/scratch/geo/fedorov/bpd6/Data/CESM/1.0/inputdata/atm/cam/physprops/mam3_mode2_rrtmg_c110318.nc',


'M:mam3_mode3:/scratch/geo/fedorov/bpd6/Data/CESM/1.0/inputdata/atm/cam/physprops/mam3_mode3_rrtmg_c110318.nc'

Hi Hsalah,

I don't think I fully understand your question, but you can specify where the model will look for input data by modifying the variable DIN_LOC_ROOT in the env_run.xml file in your case directory. Also please note that if you are using only default inputs then you can run the script:

./check_input_data --download

in your case directory to download the input files into the directory specified by DIN_LOC_ROOT.

However, if you have any personally-created input files then you will need to add them manually by adding the namelist variables of interest to your user_nl_cam file and then modifying them to point to the correct inputs. For example, if you need to point to a modified "ncdata" file, then you would add the line:

ncdata = '/path/to/file/<ncdata_file_name>.nc'

to user_nl_cam, with the actual path and file name being whatever you have decided on.

Hope that helps, and have a great day!
