摘      要：Studies of the Earth s radiation budget from polar orbiting satellite systems, such as the forthcoming NASA Earth Radiation Budget Experiment, suffer from errors due to a poor temporal sampling of the diurnal variations in the radiation field. A knowledge of the causes and magnitudes of such variations is of importance in minimising these errors. This paper presents data on daily mean radiation budget parameters, together with their variation over the daylight hours, relating them to physical processes within the earth/atmosphere system. The most significant cause of variability is shown to be persistent high level cloud. The relative magnitude of cloud induced variability in the visible and infrared spectral regions is derived. © 1985.
