6.5. Temporal and spatial analysis of the global land surface albedo

6.5.1. The method to calculate regional average and monthly average albedo

Albedo significantly influences the surface net radiation and plays an important role in global and regional meteorological modeling, for which surface albedo data products can provide helpful information. The land surface albedo is determined by many factors, such as vegetation cover, snow/ice, and the characteristics of clouds and aerosols in the atmosphere (Jin et al., 2002a,b; Zhou et al., 2003; Greenfell and Perovich, 2004), which cause seasonal changes and regional differences. Therefore, many meteorology studies have investigated the land surface albedo and its changing trend on the global ...
