Abstract :
GLASS albedo is a newly developed global daily land- surface broadband albedo product with 1-km spatial resolution. There are two main deficiencies in GLASS albedo products: 1) large areas of missing data mainly caused by cloud coverage; 2) sharp fluctuations in time series due to noise and uncertainties in inversion algorithm. This paper proposed a temporal filtering algorithm to reconstruct daily albedo series from GLASS albedo products. Validation results show that this algorithm can fill data gaps and smooth albedo series effectively.
