Worked on maintaining framework compatibility for the GEOS-ESM/GOCART repository by updating the Aerosol_Cap.F90 module to support ESMF 8.8.0 and MAPL 2.53.0. Refactored initialization and specialization routines, adapting entry points for model advertisement and data initialization to match the latest framework APIs. Focused on isolating framework-dependent changes to improve startup reliability and maintainability, reducing the risk of future incompatibilities. Ensured that builds remained reproducible and stable in both CI and production environments. Utilized Fortran, ESMF, and MAPL throughout the process, addressing a critical bug related to startup and data initialization introduced by the framework updates.
