Observation and estimation of evaporation from the ground surface of the cryosphere in eastern Asia
Abstract The characteristics of evaporation from the ground surface of Asian cryosphere sites are presented, as estimated by the lysimeter method, a profile method, and a heat budget method. The observation sites were located on the eastern Tibetan Plateau, in the Qilian and Tianshan Mountains of Ch...
