Abstract
We report the tropospheric transmissions at 22 GHz and 110 GHz by analyzing spectra measured by different ground-based microwave radiometers at Seoul. The transmittance is calculated from the opacities, which are the sum of absorption coefficients of the atmosphere. The opacities are derived from the tipping curve calibration for 22 GHz and the radiative transfer equation, from estimated tropospheric temperature for 110 GHz. The transmittance at these frequencies shows strong seasonal variation as it depends on the water vapor content of the troposphere. Although their variation scales differ, both transmittances show a linear relationship. In addition, the transmittances are derived from the 110 GHz ozone spectrum using quadratic equations
