- Changed pointer in XX2G_instance rc files to v2.x.x aerosol optical property
LUTs now based on GEOSmie and with dimensions renamed and reordered as above
- Updated version of volcanic sulfur emissions for AMIP configuration to v202601
- Update aerosol optics bands files to default to RRTMGP bands, rather than RRTMG (as GEOSgcm v12 has switched to RRTMGP)
- NOTE: This means users needing RRTMG bands will need to update at run time. See https://github.com/GEOS-ESM/GEOSgcm_App/pull/878 for changes needed at run-time for GEOSgcm
