Welcome to the CICE wiki!

ESCOMP/CICE main is a direct fork of CICE Consortium main. This should be synced frequently, i.e. once a month or more as needed. Tags and PRs are currently handled through the cesm3_cice branch. This should hopefully change in the near future. However, during periods of rapid development a special branch is needed.

1. Make a CESM tag.

• CICE has a submodule Icepack. Currently, the icepack hashes are pointing to ESCOMP/Icepack. However, for PRs back to the Consortium, it should be pointing to hashes on CICE Consortium Icepack main.
• Update Icepack if needed either https://github.com/ESCOMP/Icepack or https://github.com/CICE-Consortium/Icepack
• add the appropriate hash to .gitmodules
• sometimes a submodule update --init is required
• Commit and push changes from CICE to cesm3_cice and tag.
• tags for cesm3_cice are of the form cice6_6_1_YYYYMMDD
• Add tag to CESM_CICE interface layer.

2. PRs back to CICE Consortium

• these require unique branches
• make a branch from ESCOMP/CICE main
• Add your development work for CICE/Icepack and commit to ESCOMP branch
• Issue PR to CICE Consortium main from branch
• see CICE / Icepack developers guide for more on this
