Megha-Tropiques was a satellite mission to study the water cycle in the tropical atmosphere in the context of climate change.

[4] A collaborative effort between Indian Space Research Organisation (ISRO) and French Centre National d’Etudes Spatiales (CNES), Megha-Tropiques was successfully deployed into orbit by a PSLV rocket in October 2011.

[5][6] With the progress made by GEWEX (Global Energy and Water Cycle Experiment), Megha-Tropiques was designed to understand tropical meteorological and climatic processes, by obtaining reliable statistics on the water and energy budget of the tropical atmosphere.

[10] Megha-Tropiques instruments allowed simultaneous observation of three interrelated components of the atmospheric engine: water vapor, condensed water (clouds and precipitations), and radiative fluxes, facilitating the repetitive sampling of the inter-tropical zone over long periods of time.

[16] In April 2022, ISRO announced the end of mission for the satellite because of issues with the attitude control sub-system.
