It was the first time this renewed group of investigators met. Drs Viltard and Roca participated to the event as usual (the french MT scientists are part of the team through a no-cost proposal since 2007). And it was a great opportuniy to update the international science community on the status of the Megha-Tropiques mission. The MT presentation can be found here (dmdocuments/Roca_PMM2013_Annapolis_final.pdf) . This meeting also confirmed the insolent TRMM life expectancy (expected to acquire data up to 2017) and the readiness for launch of the GPM core in Feb 2014. As far as the GPM constellation is concerned it now includes around 10 platforms since the 183GHz sounders are fully now endorsed as useful measurements for rain estimation. This of course includes the SAPHIR instrument and the alike MHS, ATMS etc... Please also note the new multimedia materials made available to communicate about GPM that can be easily found on the GPM web site (http://pmm.nasa.gov/precipitation-measurement-missions) .

These encouraging results are supportive of a full release of the data sets in the coming weeks. A communiqué by the two spaces agencies, ISRO and CNES will be soon released with details on the calendar. Note also that the delegation was kindly invited at the french consulate in Bangalore where the consul, Mr Eric Lavertu and the new attaché for science and technology Dr Jenifer Clark, provided a warm welcome to the french scientists.

See an example of trajectory of a radio-souding here (index.php?option=com_content task=view id=191 Itemid=82) . The second phase of this Campaign is aimed at sampling the moister atmosphere in the heart of the African Monsson and will cover the 17th July - 2nd August period. Every day a pair of radio sounding is launched in synchronization with Megha-Tropiques overpasses. The 2 RS are launched 35 min apart to allow simultaneous sampling of the lower and upper part of the troposphere while MT is overpassing.

The Megha-Tropiques data set is an invaluable source of information for the community working on tropical meteorology and hurricane forecast. Nicolas Viltard gave two talks, one on the mission status and the other on the MT-II field campaign during DYNAMO in the Maldives in November-December 2011. Both talks (recorded during the conference) are available at: http://ams.confex.com/ams/30Hurricane/webprogram/ (http://ams.confex.com/ams/30Hurricane/webprogram/) when entering viltard in the search field.

It also gather the team of scientists that will form the Megha-tropiques French Science team. The topics of interests span a wide domain, ranging from tropical meteorology and hydrology to microphyiscs and scaterring radiative transfer in the micro wave region ! The agenda of the discussions is available here (colloque-bordeaux.html) and soon will also be the presentations. Beyond the actual science, the participants enjoyed being all together (the exceptionnal weather and the local gastronomy clearly contributed !). And it was nice wittnessing the french tropical science community gearing up for the use of its new tool. All are now eagerly awaiting the data !

TAPEER stands for Tropical Amount of Precipitation with an Estimate of ERrors. It provides precipitation estimations and associated errors at the one-degree/one-day accumulated scale. To characterize the evolution of the energy budget along the life cycle of convective systems, a MT level 4 product, called MCS composite has been developped. The ATBD (Algorithm Theoritical Basis Document) of the TAPEER algorithm and MCS composite algorithm have been published under the Megha-Tropiques Technical Memorandum (available-documents/mttm/index.html) (MTTM) n°4 and n°5.
