dc.description.abstractTo investigate the absorption of shortwave radiation by clouds, we have collocated satellite and surface measurements of shortwave radiation at several locations. Considerable effort has been directed toward understanding and minimizing sampling errors caused by the satellite measurements being instantaneous and over a grid that is much larger than the field of view of an upward facing surface pyranometer. The collocated data indicate that clouds absorb considerably more shortwave radiation than is predicted by theoretical models. This is consistent with the finding from both satellite and aircraft measurements that observed clouds are darker than model clouds. In the limit of thick clouds, observed top-of-the-atmosphere albedos do not exceed a value of 0.7, whereas in models the maximum albedo can be 0.8.en_US
dc.description.sponsorshipWe arc grateful to Gary G. Gibson for providing us with the ERBS and NOAA 9 scanner intercomparison statistics that are summarized in Figure 14b, to Peter Pilewskic for the ER-2 TOGA-COARE albcdos shown in Figure 15, and to Bruce P. Briegleb for performing the CCM2 simulation.
