Announcement of Opportunity

The Announcement of opportunity is now closed since April 2010.
The MT International Announcement ofOpportunity, released by CNES and ISRO, aims at opening the access to the datafrom MT Payloads to the global scientific community through the submission ofno cost research proposals. Proposals are welcome on the use of both the rawmeasurements (the Level 1 radiances) and the geophysical products. All thetopics, including cal/val activities, related to the scientific objectives ofthe MT Mission arewelcome.
The methodology for answering the Call ispresented in this document (IAO-MEGHA-TROPIQUES). Note the deadline forsubmission: March 30th 2010. Information related to the Level 1 dataare also found there. Note that real time access data is not part of this Calland inquiry about NRT Level 1 data should be directed to CNES and ISRO.
Below we further discuss the details of theavailable French geophysical products. There are 5 main processing chainsyielding to a variety of products proposed at various scales over the 30°S-30°Nregion over both ocean and land. The table below summarizes all the productsavailable. More information is given on the "More here" link.
In case of any questions, please do nothesitate to contact the PI :
