A Clear-sky Daily DLR product from the FY3D MERSI-2 observations

A daily clear-sky surface downward longwave radiation in the Arctic (60°N-90°N), produced from the FY-3D MERSI-2 thermal infrared (TIR) top-of-atmosphere (TOA) radiances, using the extremely randomized trees (ERT) machine learning algorithm. The dataset was firstly generated from the instantaneous M...
