Abstract :
The results of aircraft microwave K- and Ka-band radiometer measurements used for liquid water and water vapour content recovering are presented. The K-band dual-frequency radiometer has been developed in Space Research Institute (Russia). This radiometer provides simultaneous measurements of brightness temperature in two frequency bands due to adjustable dual-frequency filter. The comparison of results obtained by two different retrieval techniques shows good agreement, so also under strong cloud condition
