The globally integrated and homogenized solar surface radiation dataset includes the homogenized SSR dataset (SSRIHgrid) and the AI-reconstructed SSR dataset (SSRIH20CR). SSRIHgrid is a 5°×5° homogenized global monthly SSR anomalies dataset. SSRIH20CR is a 5°×2.5° full-coverage monthly land (except for Antarctica) SSR anomalies reconstructed dataset based on the 20CRv3 AI model.
