Abstract :
MEGHA-TROPIQUES is an CNES-ISRO collaborative satellite mission designed to study atmospheric water cycles and energy exchanges in the tropical belt. The satellite was launched successfully by ISRO in October 2011 from Sriharikota launch pad (India). The satellite is carrying 4 instruments · MADRAS Instrument : A conical scanning microwave imager designed to estimate precipitations and clouds properties. · SAPHIR Instrument : A microwave sensor used to retrieve vertical humidity profiles. · SCARAB Instrument : An wide band optical radiometer used to retrieve Earth Radiation budget parameters. · GPS-ROS instrument : The sensor will provide temperature and humidity profiles of the Earth´s atmosphere After 7 months of in orbit operation, this paper is presenting the measured in orbit performances of the French sensors or subsystems.
