Oct 1, 2025Month: 2025-10 — Summary: The ESCOMP/atmospheric_physics project delivered a critical CCPP metadata compatibility fix to ensure dimension index names conform to updated framework rules. Specifically, we updated .meta files to remove integer prefixes from dimension definitions and ensured only standard names are used for dimension indices, aligning with the CCPP framework update. This fix prevents runtime compatibility issues, reduces manual intervention during model initialization, and supports smoother CI/CD and production runs. The change is tracked under commit 72632b99489221ab452dbc2f276cf0e8efcd3063 with the message 'CCPP framework only allows standard names as dimension indices (#264)'.
