We simultaneously measured atmospheric emission and absorption under clear sky conditions at frequencies of 15 and 35 GHz and compared the values with those calculated from the radiative transfer equation. The measurements show that atmospheric attenuation determined from emission and absorption measurements agree within experimental error and that the calculated values of attenuation agree with the measurements on a statistical basis when the Gross form factor is used with the model of a plane stratified atmosphere.
