WCRP CMIP International Project Office is soliciting feedback for the CMIP7 Data Request. Detailed instruction is outlined on the v1.0beta release webpage.

One consolidated response from each modelling centre should be provided on the spread sheet: link for modelling centres.

More detailed technical feedback to:https://bit.ly/CMIP-variable-comment.

Background information on E3SM’s CMIP contribution

Experiments we always produce for CMIP:

DECK+: DECK, DAMIP (e.g. single-forcing simulations), one or two scenarios for ScenarioMIP.

Standard output variables we reformat and submit to CMIP:

For v1 and v2 simulation campaigns, we submit around 130 variables per coupled simulation. This variable list is highly correlated to the CMIP7 requested core set of Base line climate variables for earth system model output (one of the so-called Opportunity variable groups). This is an all-purpose set of variables suitable for any MIPs, targeting 132 variables.

Default Set of Model Output for ESGF publication

For v3, Before launching v3 simulation campaign, Chris led this effort to better define simulation output, and we also engaged component group leaders for CMIP variable contribution. The feedback as I recall is listed as follows:

· Atmosphere and Land, the variables to contribute would be the intersection of model output and the CMIP DECK requested

· Output from MPAS sea-ice will remain the v2 output list.

Which means E3SM v3 will contribute to CMIP6 much more than 130 variables. And from Infrastructure side, we are planning to expand e3sm_to_cmip for adding new atmosphere and land variables.
