Abstract : Effects of atmospheric changes on attenuation in the atmosphere are examined for the 5-mm-wavelength region of the electromagnetic spectrum (48 to 72 GHz). Attenuation versus frequency and altitude for vertical transmission through the atmosphere, caused by oxygen absorption, are tabulated for geographical and seasonal model atmospheres. The attenuation effects of atmospheric water formations are discussed and compared to oxygen attenuation. (Author)
