Abstract : OF THE TOTAL INSOLATION REACHING THE TOP OF THE ATMOSPHERE, LESS THAN HALF HEATS THE AIR. The insolation is first reduced by the sky and cloud albedo, then is further reduced by the ground albedo. The remaining portion is reduced by the evapo-transpiration process. The insolation loss due to the evapo-transpiration process is a function of soil moisture, soil type and vegetation. The maximum loss occurs when the soil is saturated and decreases to the minimum value when the soil reaches its driest state. An estimation of the insolation loss due to soil moisture as a function of time is determined by statistical methods. (Author)
