The Measurements of the Atmospheric Radio Noise at the 6mm-Wavelength

Abstract

The earth's atmospheric emission at the 6 mm-wavelength was observed from November 1972 to August 1973 with the 1500 mm-diameter Cassegrain Antenna. The atmospheric absorption and emission coefficients a had the values of between 0.25 and 0.35. On the other hand, it has the numerical calculation that the absorption and emission coefficients include both the components O2 molecular and the water vaper in the earth's atmosphere. The estimations of the effective thickness for the water vaper and O2 molecular in the atmosphere were made using the absorption coefficient O2 molecular ane water vaper.
