13/04/2015: SAPHIR observations assimilation in Météo-France new operational model suite
Since April 13, Météo-France new operational suite of Numerical Weather Prediction systems have been assimilating SAPHIR observations in real time. The new versions of the ARPEGE global model, running at 7.5km over Europe and 36 km at the antipodes, as well as of the regional model ALADIN Réunion therefore benefit from SAPHIR data, disseminated in real time by Eumetsat. The figure below shows in orange the location of SAPHIR observations which were assimilated within the ARPEGE analysis of April 15 at 00H UTC, together with the assimilated observations from other AMSU-B/MHS microwave sounders.

The monitoring of SAPHIR observations as well as the monitoring of other observations used within the ARPEGE 4D-Var assimilation system is available online:
Please select ATOVS instruments in the satellite observations list, MEGHA-TROPIQUES in the satellite list and AMSU-B/MHS/SAPHIR in the instrument list to display time series of innovation statistics (observation - model simulation) for each of the 6 SAPHIR channels.

Save the date: 29-30 june 2015, Joint workshop on uncertainties at 183 GHz, Paris

We are pleased to announce the "Joint workshop on uncertainties at 183GHz", which is aimed at identifying  possible explanations for biases observed between measured and simulated  183 GHz data.

The workshop, sponsored by the Megha-Tropiques mission, will be held at University Pierre et Marie Curie (Paris,  France) from 29-30 June 2015.

March 2015: Release of the experimental version of the TAPEER rainfall dataset for JJAS 2012-2014
We are happy to inform you about the release of an experimental version of the TAPEER rainfall data. 
The product consists in 1° x 1 ° x 1 day accumulated rainfall estimate (in mm) and the associated uncertainty estimation. 
The release concerns the June, July, August and September 2012, 2013 and 2014 over the tropical belt (30s-30n). The format is netCDF. 

The TAPEER approach merges IR geostationary data at full resolution with the GPM constellation microwave imagers, including SAPHIR on board Megha-Tropiques. 
 

The finalized dataset, covering all the period since the launch of Megha-Tropiques, will be released in the coming months via the ICARE center  in France. 
We will keep you posted on this formal release. By then any feedback will be appreciated as it will help to improve the products before this formal release.
