Abstract :
The optimal pair of frequencies for dual-frequency radiometer presuming the presence of clouds and accounting on the possible accuracy of the instrument are investigated. The water vapor and liquid water contents retrieved from microwave measurements with dual-frequency radiometer were averaged over various types of clouds. To reduce the influence of strong cloud conditions the third frequency band is proposed. Optimal frequency set is estimated in the case of zenith-looking observation
