MEGHA-TROPIQUES is an CNES-ISRO collaborative satellite mission designed to study processes related to large
tropical convective systems and their life cycle, and to provide key elements related to atmospheric energy and water
budget at various time and space scales. The satellite will perform high repetitive measurements using a low inclined
(20°) orbit, and will carry 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
The MEGHA-TROPIQUES satellite is planned to be launched in 2011 by the Indian PSLV launcher. This paper
presents the mission, the satellite definition and the measured performances of the sensors.
