Sentinel-2 : an ESA's operational mission
Sentinel-2 is ESA's operational mission for the observation of land surfaces with a decametric resolution.
Two Sentinel-2 satellites will soon be launched : official launch dates are end of 2013 for Sentinel 2A, and beginning of 2015 for Sentinel 2B.
They will provide a systematic coverage of all lands with a repetitivity of 10 days with one satellite, and 5 days with two. Images will have a swath of 290 km, and a resolution of 10m, 20m or 60m depending on the spectral bands (there are 13 spectral bands including 3 in the Short Wave InfraRed (SWIR). The Sentinel-2 satellite system will be largely better than LANDSAT, on all aspects except the presence of thermal infra-red band.
Sentinel-2 spectral bands
ESA is responsible for the development of the spacecrafts, instruments and ground segment. Within a cooperation agreement, CNES is in charge of :
Level 2 processing :
CESBIO has studied the relevance of the algorithms designed for VENµS to Sentinel-2 data. The main differences between Sentinel-2 and Venµs lie in :
Venµs Level 2 algorithms have been applied to LANDSAT data to test their applicability to Sentinel-2 : using time series from two LANDSAT satellites, with a field of view of 180 km and the availability of SWIR bands, we obtain data sets rather close to those of Sentinel-2.
The applicability of Venµs algorithms has been assessed :
