Some summer news about Sentinel-2 and THEIA’s level 2A production

Theia – MUSCATE

I had a week of work in the middle of my holidays, which enabled be to see how the work on Sentinel-2  L2A data distribution is progressing. My colleagues who worked all July (Dominique, Joelle, Céline…) did a great job : they were able to process a large data set of L2A products with MUSCATE : all the images taken by Sentinel-2 between November 2015 and end of july 2016. The quicklooks may be seen here. It is not by pure perversity that we show the data without enabling you to download them (a few demonstration products are available for download). The distribution server is still a provisional facility, and we are still chasing the last bugs (and we found some 🙁 ) If the bug correction does not take too long, we should be able to deliver the L2A products generated by MACCS within MUSCATE from September, starting with France and extending progressively.

Sentinel-2A

Meanwhile, Sentinel-2 acquisitions above Europe and Africa are now steady, with an unavailability rate which decreased a lot since beginning of June. However, we still don’t know when we will have 10 days repetitivity for the whole earth land masses.  The data are also still ortho-rectified without ground control points, with a reduce registration accuracy. ESA ‘s ramp-up phase scenario still mentions that the routine phase should start one year after launch.  The system is late by more than a month; and above all, we still do not have an official date for this.  However, this system is built for 15 years, we can afford some patience… 

Sentinel-2B

Sentinel-2B launcher is now VEGA and not Rockot anymore. Sentinel-2 will therefore be launched from Kourou. There is still a launch possibility in December, but the most probable would be March 2017.

BIOMASS, the third launched satellite mission designed at CESBIO !

After SMOS in 2009, and VENµS in 2017, the CESBIO Laboratory is very proud to see its third proposed mission, Biomass, reach orbit. As always, it has been a long journey from the idea, at the beginning of the century, to the selection in 2013 as the seventh Earth Explorer Mission by ESA, to the […]

Sentinel-2 reveals the surface deformation after the 2025 Myanmar earthquake

Sentinel-2 captured several clear-sky images of Myanmar before and after the 28 March 2025 earthquake. The animation below shows a 5-day apart sequence of images captured by Sentinel-2B and Sentinel-2C (10 m resolution) near the epicenter located close to Mandalay. The surface slip due to the earthquake follows the Sagaing Fault, a major fault in […]

Evolution de l’altitude de la ligne de neige au cours des 41 dernières années dans le bassin versant du Vénéon (Oisans)

Pour contribuer à caractériser les conditions hydrométéorologiques lors de la crue torrentielle qui a frappé la Bérarde en juin, j’ai analysé une nouvelle série de cartes d’enneigement qui couvre la période 1984-2024 [1]. Grâce à la profondeur temporelle de cette série, on constate que l’altitude de la ligne de neige dans le bassin versant du […]
