Nudge test CESM2.2 for MERRA2

[nuvolet]

Hi everyone,

I would like to try a nudge test using CESM2.2 for MERRA2.
I started a case like this:

./create_newcase --case nudge_test --compset FCnudged_case5 --res f09_f09_mg17

And I got this message:

This compset and grid combination is untested in CESM. Override this warning with the --run-unsupported option to create_newcase.

Therefore I started a new case like this
./create_newcase --case nudge_test --compset FCnudged_case5 --res f09_f09_mg17 --run-unsupported
./xmlchange NTHRDS=1,NTASKS=12
./xmlchange RUN_STARTDATE=20100101,STOP_OPTION=ndays,STOP_N=1,STOP_DATE=-999,DOUT_S=FALSE
./case.setup
./case.build --skip-provenance-check
./case.submit


Then it looks that cam is missing files:

Model cam missing file solar_irrad_data_file = '$my_path/CESM2.2/data/input/atm/cam/solar/SolarForcingCMIP6_18491230-23000102_c20200615.nc'
Model cam missing file ncdata = '$my_path/CESM2.2/data/input/atm/cam/inic/fv/f.e22.FC2010climo.f09_f09_mg17.cam6_2_022.001.cam.i.0016-01-01-00000_c200610.nc'
Model cam missing file nudge_path = '$my_path/CESM2.2/data/input/atm/cam/met/nudging/MERRA2_fv09_32L/'

Which tries to download via wget (see CESM_build_run files enclosed)
It looks that the model is already looking for those files and also the MERRA in 32 levels.
How could I have access to those files? Is making me for user and password.

Thanks in advance

It may have been that the svn repository was down as there have been some issues with our servers in the last few days. I would suggest you try ./case.submit again.

If that still fails, there is a line in your output which says:
"To check connection and store your credential run 'svn ls https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata' and permanently store your password." There is no password needed, but when it asks to accept your credentials, indicate "p" for permanent, and it won't ask you again.

If all else fails, you can refer to:
Downloading CESM2 (CESM2.2) — CESM CESM2.2 documentation
There is a section that describes how to download data manually.

Thanks, I will try that again.

I see that at the link :https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/cam/met/nudging/MERRA2_fv09_32L/ there are only MERRA2 in 32 levels for 2003 and 2018. I s there another way to have other years in the same vertical grid?.
Thanks in advance

This collection of data is very large and has not been imported into the svn repository. Depending on the year, they range from 46Gb to 177Gb of data each year, with 1990 onward being 117Gb. If you happen to have access to NCAR's cheyenne supercomputer, all of the data files reside there and you can download what you need.

If you don't have access to cheyenne, I can look into possibly putting these on a temporary ftp site. I'm not sure if this would be doable, and the files would be there very short-term, so you would need to have storage space on your local computer system. I would need to have a complete list of the months/years that you would want and would then check with our system administrators to see if this is possible with the anticipated data volume.

I am also moving this to the CAM-Chem forum as the initial files were created by them. They perhaps have an additional proposal on how to get this data.

Cheryl,

Thanks a lot for you reply and help.
I also contacted Chi-Fan and Simone regarding these files and they also offered me same kind of help.
Definitely, I will consider that I could have access to those files and it will depend on the case.
At least I know you all can help to have them.
I will discuss with my colleague with who I am working in a extended project.

Thank again

Thanks Rebecca, I already saw the new update.
