and a total channel (0.2 - 200 µm), allowing to derive longwave radiances. The resolution at nadir will be from an orbit at . The procedures of calibration and processing of the data in order to derive fluxes from the original radiances have been set up and tested by CNES and LMD. Radio Occultation Sensor for Vertical Profiling of Temperature and Humidity (ROSA) procured from Italy for vertical profiling of temperature and humidity. Launch The Megha-Tropiques satellite was successfully placed in an orbit with an inclination of 20 degrees to the equator by the Indian Space Research Organisation through its Polar Satellite Launch Vehicle (PSLV-C18) on October 12, 2011. The PSLV-C18 was launched at 11:00 am on October 12, 2011, from the first launch pad of the Satish Dhawan Space Centre (SHAR) located in Sriharikota, Andhra Pradesh. The satellite was placed in orbit along with three micro satellites: the SRMSAT built by the SRM University, Chennai, the remote sensing satellite Jugnu from the Indian Institute of Technology Kanpur(IIT Kanpur) and the VesselSat-1 of Luxembourg to locate ships on high seas. End of Mission The original mission life was three years. The mission was extended by two years on 26 May 2015. The mission was further extended by four years on 7 October 2016. In April 2022, ISRO announced the end of mission for the satellite because of issues with the attitude control sub-system. Megha-Tropiques is presently in a 870 km orbit, which will be lowered to 300 km to prepare for the eventual disposal of the satellite.
