MUSCATE : New tiles in Europe will be added within Theia's production of Sentinel-2 L2A products

=>

Just before the holiday period, we are very happy to tell that all the sites that had been selected by Theia for the production of Sentinel-2 Level 2A products are now in production within MUSCATE. for Theia Land data center. The number of tiles processed each days often tops 400 ! Only a couple of sites need a few more days to be completed.

But that's not the only good news : given we have some production margins, we are going to add 200 tiles in Europe : Spain, Portugal, Italy, Netherlands, Belgium, Luxembourg, Switzerland, and small parts of Germany and Austria will be included in Theia's production. The new tiles, which appear in red in the image above, will be available in August, starting from images acquired in December 2016. We are also talking with other partners to generalize MAJA processing over Europe.

 

Finally, regarding Sentinel-2B, a few weeks will be necessary 1) to get some rest, 2) check the quality of our products. S2B data release from Theia should happen in September.

Muscate : toutes les zones sélectionnées ont été mises en traitement

Juste avant les vacances, nous pouvons annoncer de très bonnes nouvelles de la production de données Sentinel-2 au niveau 2A, par le centre de traitement de MUSCATE du CNES, pour le compte du centre de données Theia. Pour un petit nombre de sites, il nous faudra encore quelques jours pour terminer la production, mais le nombre de produits traités chaque jour dépasse fréquemment les 400.

Enfin, vues les bonnes performances enregistrées, nous allons ajouter environ 200 tuiles à notre liste, en Europe. L'Espagne, le Portugal, l'Italie, la Hollande, la Belgique, le Luxembourg et la Suisse, et des morceaux d'Allemagne et d'Autriche, seront entièrement incluses dans la production de Theia, à partir de décembre 2016. Les nouvelles tuiles, qui apparaissent en rouge sur l'image ci-dessus seront disponibles en août, et seront par la suite traitées en temps réel. Nous discutons aussi avec des partenaires européens pour que l'ensemble de l'Europe soit progressivement mis en production.

Quant à Sentinel-2B, laissez nous quelques semaines pour 1) prendre des vacances et 2) vérifier la qualité des résultats. Ce sera donc pour le mois de Septembre.

 

THEIA releases Sentinel-2 L2A time series over several regions of Brazil

Theia has added seven new sites in Brazil, for which Sentinel-2 L2A are produced and distributed, starting in December 2016.  These sites will be processed in near real time from now on. Data are produced by the MUSCATE system at CNES, using CNES-DLR MAJA processor. The products can be freely downloaded from https://theia.cnes.fr.

 

These sites were selected following demands from French scientists, with two main themes :

  • Land cover and land use change monitoring
  • Water body surface and turbidity

❄ Powder alarm on Theia / Avalanche de produits neige sur Theia ❄


Yesterday Theia shifted into high gear and released 1300 snow products!. These products correspond to 13 Sentinel-2 tiles covering the Western Alps (France/Italy/Switzerland), the Pyrenees (France/Spain) and the Hight Atlas (Morocco).


Hier Theia est passé à la vitesse supérieure et a mis à disposition 1300 produits neige ! Ces produits correpondent aux 13 tuiles Sentinel-2 qui couvrent les Alpes Occidentales (France/Italie/Suisse), les Pyrénées (France/Espagne) et le Haut-Atlas (Maroc).

This was made possible thanks to the great work of Dominique Clesse, Joëlle Donadieu, Céline L'Helguen, Arnaud Selle and Simon Baillarin at CNES. Merci à eux !

S2B data are now available on Copernicus hub

A very good piece of news:  ESA started distributing Sentinel2-B data on Copernicus hub, two months ahead of schedule. This is really an achievement !

Here is ESA's announcement :

Following the successful completion of the Sentinel-2B Satellite In-Orbit Commissioning Phase, we are happy to announce that access to Sentinel-2B Level-1C products will be opened to all users on 6 July .

Access to Sentinel-2B products will initially be provided through a dedicated hub accessible via the Copernicus Open Access Hub home page with public credentials. This dedicated interface will be maintained until early September, at which point both Sentinel-2A and Sentinel-2B products will be commonly accessible through the nominal Data Hub interfaces.

 

Regarding Theia L2A production, we will have to wait for the availability of the data in PEPS, by end of July, and then perform some validation before releasing the data. Given the holiday period, it will probably happen in September. However, we have already checked that our L2A products, produced with MAJA withing MUSCATE should be great, as shown in this post some time ago:

 

 

Theia distribue les premiers produits neige

Nous sommes heureux d'annoncer que Theia a mis en ligne 93 produits neige faits à partir de Sentinel-2. Ces produits correspondent à 6 tuiles qui couvrent une partie des Alpes, des Pyrénées et de l'Atlas pour une période comprise entre juillet et novembre 2016. La production opérationnelle devrait débuter cet automne (c'est-à-dire au fil de l'eau), et couvrira une surface plus grande. Nous essaierons aussi d'améliorer les produits grâce aux retours des utilisateurs.

Here is the number of L2A products we are producing every day. The visible enhanced performance is due to several reasons :
