Abstract : An orbital test program has been conducted providing radiometric measurement of the sky-CO2 horizon profile. The test program was successful and from the results the following conclusions may be drawn: 1. The radiant emittance of the earth's atmosphere, as measured in the CO2 absorption region from an orbiting satellite, agrees with predicted levels; 2. The variations in the radiant emittance for all conditions encountered during the experiment are small; 3. The horizon profile is not appreciably affected by vehicle altitude, latitude, or sun illumination; 4. No appreciable brightening (or darkening) at the earth's limb is apparent. (Author)
