Calculates isotropic radiative kernel (K_ISO) for surface albedo change based on Bright and O'Halloran (2019) https://gmd.copernicus.org/articles/12/3975/2019/

Uses satellite climatologies of Earth's shortwave radiation budget from CERES EBAF Level 3 (Observed TOA and computed surface all-sky and clear-sky fluxes; CERES-MODIS cloud properties. Clear-sky for total area of 1°x1° region.)

Code extracts relevant CERES EBAF data for Manitoba flux sites and nearby croplands and calculates K_ISO for Mar 2000 - Sept 2025.
