During December 2024, Roberto Savelli enhanced the MITgcm-contrib/ecco_darwin repository by updating documentation to clarify river runoff capabilities for the Darwin3 v05 1deg release. He focused on improving the README to detail both freshwater runoff from JRA55-do and biogeochemical runoff from Savelli et al., providing users with comprehensive configuration guidance. His work emphasized clear, traceable documentation using text-based formats, supporting reproducibility and reducing onboarding friction. By attaching detailed notes and references, Roberto enabled users to better understand and implement river runoff scenarios. The depth of his documentation work addressed user support needs and clarified feature scope for future development.
