Abstract

The mean difference in temperature ¯ΔT between a cirrus deck and an overshooting top in the shapes of an entire hemisphere and a spherical segment of a hemisphere is determined theoretically for different angles of view from a satellite sensor. The effects of changes in the area of the view and ¯ΔT on the equivalent blackbody temperature measured by a satellite are evaluated. Results show that changes in the mean temperature of the dome with the angle of view are as important as changes in the area of the field of view.
