Abstract : Radiation patterns analyzed from the listed data of Channels 2, 3, and 5 of TIROS III, Orbit 4, 12 July 1961, over the United States are compared with the cloud patterns shown on nearly c6ncurrent cloud photographs. It is found that both the data from Channel 3 and Channel 5 can outline accurately all photographed cloud features of a dimension larger than 1- x 1-degree latitude. PATTERNS OF Channel 5 albedo are related to a nephanalysis from surface observations of cloudiness and precipitation. Areas with only extensive cirriform cloudiness are characterized by low albedos. The highest albedos coincide with areas of precipitating clouds. A qualitative interpretation in terms of cloud type from a combination of Channel 2 effective temperatures and either Channel 3 or Channel 5 albedos is suggested. (Author)
