Abstract : A scanning monochromator system to measure the earth's albedo in the wavelength interval from 1600 to 3100 A has been developed to the final design stage. Spectrometers flown on Air Force low-orbiting satellites have provided data on the fluxes, energy distributions, and lifetimes of Soviet-injected electrons; another study concerning the radiation belts dealt with the role of very-low-frequency waves in precipitating fast electrons. Also, data from measurements of electron fluxes and spectra above 900 kev at altitudes between 200 and 700 km have been analyzed. A Faraday Cup detector has been constructed for use in measuring low-energy electrons and protons in space. The Particle Radiation Mapping Program (PRAM) is continuing; a summary is presented of the first instrument payload to be flown. Optical radiation measurements have been made to the vertical distribution of ozone and the radiance of the atmosphere in the ultraviolet. Also, data on a satellite experiment to measure the infrared background radiations of the earth were analyzed. (Author)
