Worked on the FESOM/fesom2 repository over three months, focusing on climate and ocean modeling enhancements using Fortran and shell scripting. Addressed a critical wind coupling bug by refining nrecv handling for iceberg scenarios, improving model stability and data transfer reliability. Enhanced model configuration by restructuring namelists and adding detailed comments, streamlining user onboarding and increasing configurability. Developed more realistic ice runoff modeling by separating liquid and solid outputs. Introduced a dedicated shell environment and job scripts for the blogin@nhr.zib compute host, standardizing task setup and improving reproducibility. Emphasized environment configuration, job scheduling, and scientific computing best practices throughout.

Oct 1, 2025October 2025 monthly summary for FESOM/fesom2: Focused on stabilizing AWI-CM3 wind coupling with iceberg scenarios by fixing the nrecv handling to correctly account for two fields (zonal and meridional wind) when use_icebergs is true, eliminating a runtime error and avoiding an unnecessary oasis call.
