【Abstract】 Surface albedo and vegetation index are very important surface parameters relevant to water /heat budget. In this paper, the NOAA-AVHRR data obtained in the pilot experiment period (September, 1988) of the Atmosphere-Land Surface Processes Experiment in Heihe River basin (Heihe) are used for investigating the method of deriving surface albedo from clear- sky planetary albedo. The paper also discusses the spatial distribution characteristics of the surface albedo and vegetation index and the empirical relationship between them for the experimental area.更多还原
