[Call for inputs/comments] GMD discussion paper “Evaluation of global ocean–sea-ice model simulations based on the experimental protocols of the Ocean Model Intercomparison Project phase 2 (OMIP-2)”

A new framework for global ocean-sea-ice model simulations based on phase 2 of the Ocean Model Intercomparison Project (OMIP-2), was presented recently by CLIVAR Ocean Model Development Panel (OMDP) and other ocean model communities.

This OMIP-2 framework is assessed by comparing multi-model means from 11 CMIP6-class global ocean–sea-ice models calculated separately for the OMIP-1 and OMIP-2 simulations. Many features are very similar between these two simulations, and yet key improvements in transitioning from OMIP-1 to OMIP-2 are also identified. Thus, the present assessment justifies that future ocean–sea-ice model development and analysis studies use the OMIP-2 framework.

This work is included in the paper ‘Evaluation of global ocean–sea-ice model simulations based on the experimental protocols of the Ocean Model Intercomparison Project phase 2 (OMIP-2)”, which has been accepted for review by Geoscientific Model Development, and is now in the public discussion phase until 25 March. We are glad to invite the wide community to input or give comments on this paper.
