Improvement of water vapour retrieval in MAJA

Similarly to the aerosol retrieval, the retrieval of water vapour in MAJA atmospheric correction has also been improved, thanks to the work of Elsa Bourgeois (Cap Gemini) and Camille Desjardins (CNES). An accurate estimation of water vapour is not necessary to perform an accurate atmospheric correction, because water vapour absorption in most of Sentinel-2 bands […]

MAJA 3.1.2 with CAMS option finally validated

We had announced quite a long time ago the coming availability of MAJA 3.1 to correct for the atmospheric effects on Sentinel-2, Landsat 8 or Venµs satellites. This version brings a significant improvement in the estimation of Aerosol Optical Thickness, thanks to the use of Copernicus Atmosphere Monitoring Service (CAMS) data to constrain the aerosol […]

THEIA : Une nouvelle zone de production des données Sentinel-2 L2A au Sahel

=>La production des données Sentinel-2 au niveau 2A, avec la chaîne MAJA, par le centre MUSCATE de Theia est maintenant rapide et efficace, nous disposons donc de quelques marges pour ajouter de nouvelles zones (les zones actuelles sont visibles ici). Les organismes français intéressés par l’ajout de nouvelles zones peuvent d’ailleurs me contacter, il devrait […]

[Nouvelles de MUSCATE] Un été très productif

=> (Mise à jour le 4 octobre 2018) Cet été, alors que la plupart d’entre nous prenions des coups de soleil sur la plage, nous faisions dévorer par des moustiques, attrapions des courbatures en rando, ou faisions de longues siestes pour nous remettre de nuits fatigantes, les équipes de production et de distribution de MUSCATE […]

[MUSCATE News] A very productive summer

=> Updated on October 4th This summer, while most of us were getting sunburnt near the coast, or getting sore legs after hiking in mountains, or having long naps after hectic nights, the lucky MUSCATE teams stayed at work, with a good and efficient air conditioning, convenient armchairs, fast computers and accessed to the best canteen […]

On-demand SENTINEL2 L2A processing with MAJA on PEPS

Update : we added a script to submit and download MAJA jobs on PEPS Getting a Sentinel-2 L2A product (with atmospheric correction and cloud detection) anywhere has never been so easy.  Until now, you had two options to access to Sentinel-2 L2A products obtained from the MAJA processor : Starting from today, there is another […]

A seamless and cloudless Sentinel-2 image of France in July 2018

=> UPDATE: resolution improved to 20m !  I had to tinker a couple of days with Theia’s Sentinel-2 monthly syntheses, in order to produce the mosaic below. For that, I used: This mosaic best resolution is 20m. It is already requiring 8 GB. We could have provided it at 10m resolution, but it would have […]
