Li Pan focused on maintaining framework compatibility for the GEOS-ESM/GOCART repository, updating the Aerosol_Cap.F90 module to support ESMF 8.8.0 and MAPL 2.53.0. Using Fortran and leveraging expertise in ESMF and MAPL, Li refactored initialization and specialization routines, adapting entry points for model advertisement and data initialization to align with new framework APIs. This work addressed startup and data initialization changes, ensuring continued reproducibility and stability in both CI and production environments. By isolating framework-dependent changes, Li reduced the risk of future incompatibilities, demonstrating a methodical approach to sustaining long-term maintainability and reliability in scientific software.
