A literature survey of meteorological satellite applications was made to define some information requirements of meteorological consumers. An attempt was made to appreciate problems involved in transmitting such information to the consumer by examining photographs of the earth taken from an Atlas nose cone. Difficulties in processing the photographs led to the development of a technique for establishing the camera axis azimuth and time of photograph from landmarks when other data cannot supply this information. Some study was devoted to determining the type of meteorological information than can be developed by using sensors which detect ultraviolet and infrared radiation rather than the visible radiation detected in photographs. In this connection, a method for determining atmospheric ozone amounts by measuring the scattered radiation at two different wave lengths in the ultraviolet was investigated to determine the theoretical ratios of radiation intensities to be expected. The view of the earths atmosphere in an infrared water absorption band was examined and found to correspond to a picture of the temperature of a constant dew point surface. Some constant dewpoint surfaces were analyzed in connection with the corresponding conventional surface and upper air weather maps. Meteorological relationships exist which should be studied further.
