Preliminary evaluation of the long-term GLASS albedo product

摘要: Land surface albedo is an important parameter to describe the radiant forcing in climate system. A long-time series of global products needed understand mechanism change. Aiming support change and Earth system studies, GLASS (Global LAnd Surface Satellites) provides long-term land product from 1981 2010, which are generated multisource remote sensing data newly developed algorithms. It critical assess quality when it released public. This paper first introduced algorithms then analyzed integrity, accuracy, robustness product. The results show that a gapless, continuous, self-consistent data-set with accuracy similar widely acknowledged MODIS MCD43 flag, provided along black-sky white-sky albedo, gives pertinent indication expected uncertainty in...
