Nimbus IV radiance measurements in the 10.5–12.5-μm window channel from the tropical Atlantic during July and August 1970 are studied. The relative frequency of cold, and presumably high clouds, is determined. The average spatial distribution of equivalent black-body temperatures associated with 38 cloud clusters is reported. Ship cloud and weather observations are studied in conjunction with the satellite data. By combining the evidence provided by the satellite and ship observations, a model of typical clouds and weather associated with cloud clusters is proposed for further study.
