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.

This page provides background information on E3SM's current CMIP contributions and potential contributions to CMIP7, as well as simplified instructions for navigating the CMIP7 Data Request to gather feedback from component and science group leads.

Background information on E3SM’s CMIP contribution

Experiments we always routinely produce for CMIPCMIP6:

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

• Some possibilities proposed by Chris Golaz and Wuyin Lin for CMIP7:

  • Exact same model version as v3.LR.

  • v3_1.LR: Minor updates to v3.LR (based on what we learn from analysis of v3.LR).

  • v3.HR

Forcing data for CMIP7 is scheduled to release March 2025.

Standard output variables we reformat and submit to CMIP:

For v1 and v2 simulation campaigns, we submit around 130 variables per coupled simulation (cmorized data size is at 3GB per year). 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.

Excel Spreadsheet, but is hard can be straining on your eyes.

Potential feedback:

Based on the identified opportunities/variable groups:

• What additional experiments (besides DECK+) could benefit E3SM and should be considered for inclusion in future simulation campaigns, contributing to CMIP7?

• Are there any key variables missing from our simulation campaign and CMIP contributions?
