Abstract:

Measurements were carried out, from on board an aircraft, of the brightness of ascending long-wave radiation in the 3-30 micrometer waveband at different angles alpha over different types of underlying surface. A clear dependence was found in the nature of the angular distribution of this radiation on atmospheric stratification. Changes in the water-vapor content were not observed to play an appreciable role in the mechanism involved, with the angular distribution of the ascending long-wave radiation at different levels of the troposphere basically determined by the vertical temperature profile.
