Concept information
Preferred term
Megha-Tropiques
Definition
- This mission was studied in France in the context of GEWEX (Global Energy and Water cycle Experiment). For understanding tropical meteorological and climatic processes, it appeared necessary to obtain reliable statistics on the water and energy budget of the tropical atmosphere and to describe the evolution of its systems (monsoons, cyclones, …) at appropriate time scales. In parallel, tropical atmospheric and oceanic missions were also studied in India, which is directly concerned by these phenomena. The first originality of MEGHA-TROPIQUES is to associate three radiometric instruments allowing to observe simultaneously three interrelated components of the atmospheric engine : water vapour, condensed water (clouds and precipitations), and radiative fluxes. The second is to privilege the sampling of the intertropical zone, accounting for the large time-space variability of the tropical phenomena. Moreover, the MEGHA-TROPIQUES microwave radiometer MADRAS could be one element complementing the constellation of mini-satellites of the Global Precipitation Mission . (en)
