Spatially generalizable bias correction of satellite solar radiation for regional climate assessment—a case study in Japan Open
Evaluations of model- and reanalysis-based surface solar radiation (SSR) products often depend on satellite-derived estimates, which can be biased, particularly under broken-cloud conditions or over high-albedo surfaces. In this study, we …
