Downscaling solar radiation in the Canary Islands with GAM

--> --> --> I’ve been meaning to write a post on how we can push interpolation and downscaling— beyond the usual tools like linear regression or kriging when dealing with climate data. This post illustrates a statistical downscaling workflow for monthly radiation over the Canary Islands using a Generalized Additive Model (GAM). We start from a coarse ~5km signal, learn its relationship with…
