Comparison of radio-sounding profiles for cloud attenuation analysis in the tropical region

In this paper, comparisons of radio-sounding profiles with different resolutions are performed for prediction of cloud attenuation in the tropical region. The Salonen and Uppala model which was reported to have an excellent prediction capability for cloud attenuation is used. One-month data is processed for calculating the height of cloud base, the 0°C isothermal level, and the cloud attenuation. The results show that the free radiosonde data with low resolution is sufficient for the cloud attenuation prediction.
