The following will be submitted to CMIP6 to register E3SM-2-0 model by submitting an issue in github https://github.com/WCRP-CMIP/CMIP6_CVs/issues/new . 

See the table with all registered model versions and activities (experiment types): https://wcrp-cmip.github.io/CMIP6_CVs/docs/CMIP6_source_id.html

Renata: Removed the note ( Note in geen below) from v2.0 registration, changed activity to exclude CFMIP and ScenarioMIP. Will need to add them when we will be publishing to these activities.

           Note: initial submission to include CMIP, RFMIP, DAMIP. CFMIP and ScenarioMIP will follow later.  

 submitted as issue: https://github.com/WCRP-CMIP/CMIP6_CVs/issues/1127

  The E3SM-2-0 is now registered, NOTE: that the nominal_resolution can only be 50km or 100km, so the values were updated. Also, the registration is now closed for new models, we have the publication imminent and got an exception. I have added the CFMIP and ScenarioMIP activities, so we can publish to those activities as well.

 There is an issue with the size of the string our description creates. All the info is concatenated and becomes a part of the NetCDF attribute string, that has currently (in CMOR) a limit of 1024 characters. We need to cut 105 characters to fit within the limit, below is the original string and my proposition on shortening it out. I also noticed that we did not have any info on vertical layers so added it to the atmos specifications as a sting: "2 vertical layers w/ top at 60 km". See below for changes - old text in red, shortened in green, or added in teal

Original (current) string:

E3SM 2.0 (2022): \naerosol: MAM4 with new features in resuspension, marine organics, secondary organics, and dust (same grid as atmos physics)\natmos: EAM (v2.0, cubed sphere spectral-element grid; 5400 elements, 30x30 per cube face. Dynamics: degree 3 (p=3) polynomials within each spectral element, 112 km average resolution. Physics: 2x2 finite volume cells within each spectral element, 1.5 degree (168 km) average grid spacing)\natmosChem: Troposphere specified oxidants (except passive ozone with the lower boundary sink) for aerosols. Stratosphere linearized interactive ozone (LINOZ v2) (same grid as atmos physics)\nland: ELM (v1.0, same grid as atmos physics, satellite phenology mode), MOSART (v1.0, 0.5 degree latitude/longitude grid)\nlandIce: none\nocean: MPAS-Ocean (E3SMv2.0, EC30to60E2r2 unstructured SVTs mesh with 236853 cells and 719506 edges, variable resolution 60 km to 30 km; 60 levels; top grid cell 0-10 m)\nocnBgchem: none\nseaIce: MPAS-Seaice (E3SMv2.0, EC30to60E2r2 unstructured SVTs mesh with 236853 cells and 719506 edges, variable resolution 60 km to 30 km; 5 ice categories, 7 ice layers, 5 snow layers)

1136 characters as counted in Word: go to Review, click on Word Count, I am looking at "Characters (with spaces)"

Proposed shortened string:
