Using radiosonde data and other related observations in the TOGA-COARE IOP(fromNovember 1,1992 to February 28,1993),the microwave attenuation of non-precipitating clouds isinvestigated based on microwave radiative transfer model(MRTM)at the specific frequencies of6.8,10.65,13.9,19.35,22.235,37.0,85.5 and 90.0 GHz.Besides,utilizing the data of theairborne radar and radiometer at 13.8 GHz in the IOP(Intensive Observation Period),verticalstructure models for different types of precipitating clouds are obtained,and also the microwaveattenuation of precipitating cloud is studied.Some statistical characteristics of 13.8 GHzmicrowave path integrated attenuation for stratiform and convective precipitating clouds arepresented.The results given here are valuable for the spaceborne microwave remote sensing ofprecipitation,and the cloud and precipitation attenuation corrections in the spaceborne microwaveremote sensing of earth surface over tropical ocean area.
