Daily measurements of atmospheric attenuation at 15 and 35 GHz were made over a 6‐month period using the sum as a source. Curves showmg percentage time distributions at various zenith angles and attenuation as a function of zenith angle for various weather conditions are presented. Clear sky attenuations were found to be well correlated with absolute humidity. The effect of solar flux variations is discussed.
