Impact of cloud effective temperature on cloud attenuation in tropical region

In this paper, cloud attenuation in the tropical region is investigated based on the reduced liquid water content method for finding the most suitable cloud effective temperature. One-year radiosonde data is processed for calculating cloud attenuation at different frequencies and effective temperatures. The results show that for the prediction of cloud attenuation in the frequency range of 10 GHz to 60 GHz, a 0°C cloud effective temperature should be used for frequencies below 40 GHz and a -1°C cloud effective temperature should be used for frequencies above 40 GHz.
