Hi Dharmendra,

Looking at your case directory, you have changed the start date to 2019-09-01, which means that the model no longer has a default initial conditions (ncdata) file to use.

Do you have an initial conditions file that you could point to? You can add

ncdata = '/path/to/file.nc'

to your user_nl_cam

it was added, that is basic requirements in user_nl_cam

 

[peverley]

Is this your case directory on cheyenne:

/glade/scratch/dksingh/month_sep_2019_contrail_runtest

I don't see a ncdata line in the user_nl_cam

I wanted to run for one month in (September) 2019 but the build was not successful
the name list was as follows:


! namelist_var = new_namelist_value

&metdata_nl

met_nudge_temp = .true.

met_data_file = '09/MERRA2_0.9x1.25_L32_20190901.nc'

met_data_path = '/glade/scratch/dksingh/09/'

met_filenames_list = '/glade/scratch/dksingh/filelist_2019_01.txt'

met_fix_mass = .true.

met_qflx_factor = 1.0

met_rlx_time = 24.

met_srf_land = .false.

met_srf_land_scale = .true.

met_srf_nudge_flux = .false.

met_srf_rad = .true.

met_srf_refs = .true.

met_srf_sst = .true.

met_srf_tau = .true.

Can you try adding the ncdata variable to your user_nl_cam file? Looking at what your other case is using, you could try adding:

ncdata = '/glade/p/cesmdata/cseg/inputdata/atm/cam/inic/fv/cami-mam3_0000-01-01_0.9x1.25_L32_c141031.nc'

you mean
i should add here
met_data_file = '01/MERRA2_0.9x1.25_L32_20190101.nc'
please check my user_nl_cam above and let me know where I should add as you are suggesting below
ncdata = '/glade/p/cesmdata/cseg/inputdata/atm/cam/inic/fv/cami-mam3_0000-01-01_0.9x1.25_L32_c141031.nc'

 

[peverley]

You can just add the ncdata = '...' line to the top of your user_nl_cam file (before &metdata_nl)

 

[dharmendraks841]

hi Peverley,
Can you see the updated name list as per your suggestion, if error please correct it?

Actually
met_data_file = '01/MERRA2_0.9x1.25_L32_20190101.nc' and ncdata = '01/MERRA2_0.9x1.25_L32_20190101.nc'
have the same first name as the start-run .nc file.

! namelist_var = new_namelist_value

&metdata_nl

ncdata = '01/MERRA2_0.9x1.25_L32_20190101.nc'

met_nudge_temp = .true.

met_data_file = '01/MERRA2_0.9x1.25_L32_20190101.nc'

met_data_path = ‘/glade/scratch/dksingh/contrail_cam6_run_2019/2019/'

met_filenames_list = '/glade/scratch/dksingh/contrail_cam6_run_2019/filelist_2019.txt'

met_fix_mass = .true.

met_qflx_factor = 1.0

met_rlx_time = 24.

met_srf_land = .false.

met_srf_land_scale = .true.

met_srf_nudge_flux = .false.

met_srf_rad = .true.

met_srf_refs = .true.

met_srf_sst = .true.

met_srf_tau = .true.

Hi,

I would put ncdata before your declaration of metdata_nl like this (it also needs to be the full path)

! namelist_var = new_namelist_value

ncdata = '/full/path/to/01/MERRA2_0.9x1.25_L32_20190101.nc'

&metdata_nl
...
