The daytime surface net radiation (R-n) product from version 4.0 Global LAnd Surface Satellite (GLASS) product suite was recently generated from Moderate Resolution Imaging Spectroradiometer data. It is the daytime average product of R-n derived from 2000 to 2015 at a spatial resolution of 0.05 degrees. This letter describes the results of validation of this new R-n product using ground measurements collected from 142 sites distributed worldwide. The overall accuracy of the GLASS daytime R-n product was satisfactory, with an R-2 of 0.80, root-mean-square error of 51.35 Wm(-2), and mean bias error of 0.11 Wm(-2). Its accuracy and quality were highly consistent for different land cover classes and elevation zones.
