The Megha-Tropiques (MT) is a joint venture climate research satellite mission between the Indian Space Research Organization (ISRO) and CNES, France to measure tropical rainfall and study the Indian monsoon. Due to be launched in 2011 from Satish Dawan Space Center in India, the MT will house three instruments namely: (1) MADRAS - Microwave Analysis and Detection of Rain and Atmospheric Structures; (2) SAPHIR - Sounding instrument to measure water vapour; and (3) ScaRab - Scanning Radiative Budget instrument. The focus of this talk will on the development of algorithms for retrieving the vertical structure of hydrometeors from the MADRAS. The MADRAS is a multi channel instrument with the following frequencies 18.7, 23.8 , 36.5, 89 and 157 GHz (all except 23.8 have both vertical and horizontal polarization). We have developed an in-house polarized RT code at IIT Madras together with candidate retrieval strategies based on Bayesian approaches. While the initial part is to produce "work horse algorithms for the mission", further exploration placing the retrieval in broader mathematical perspective is also presented. Sample results for tropical cyclones over the Indian ocean will be presented. Simulations for the MT frequencies will also be presented.
