Workshop XCAL
May 23 and 24 in Toulouse
In the frame of the Megha-Tropiques mission, ISRO/CNES and NASA have signed agreement to share Megha-Tropiques data as part of GPM. GPM (Global precipitation mission) was designed by NASA from its inception as an international satellite mission to unify and advance global precipitation measurements to serve the word community by providing the best possible global precipitation data for research and applications. The GPM concept is based on using combined radar/radiometer data from a Core Spacecraft as a reference to inter-calibrate observations for other international instruments such as Megha-Tropiques MADRAS and SAPHIR instruments.
Thanks to the Megha-Tropiques satellite low inclined orbit, MADRAS radiometer data and SAPHIR sounder data represent a valuable interest to the GPM mission, in improving the sampling over the inter-tropical zone.
Under the terms of this ISRO/CNES/NASA partnership, CNES hosted on May 23 and 24th 2013 an inter-calibration workshop (XCAL meeting) partly dedicated to performances and calibration results of Megha-Tropiques sensors and first inter-calibration results. Presentations are available just below:
