19 March 2013Measurement of surface albedo and its environmental effects over a temperate desert steppe
The albedo is an important factor of the earth's climate system, and also is a key input parameter of the regional climate models. Diurnal and seasonal characteristics of surface albedo in the temperate desert steppe were investigated during the 2008 growing season. The results showed that the diurnal dynamics of surface albedo was affected by the solar altitude, and took U-shaped with higher just after sunrise, before sunset and lower in the midday. Average surface albedo was 0.25 during the growing season, ranging from 0.20 to 0.34. Seasonal surface albedo showed higher in May, decreased in June, kept relatively stable from July to September, and increased in October. This variation was related to the phenology of the grassland canopy. Leaf area index and soil water content were the primary factors of surface albedo.
