The Copernicus Sentinel-2 mission comprises a constellation of two polar-orbiting satellites placed in the same sun-synchronous orbit, phased at 180° to each other. With its 13 spectral bands it aims at monitoring variability in land surface conditions, and its wide swath width (290 km) and high revisit time supports monitoring of Earth's surface changes.
Several derived products are generated routinely from the L0 data, including L2A.
The Sentinel-2 mission provides systematic coverage over the following areas:
In addition, the Sentinel-2 observation scenario includes observations following member states or Copernicus Services requests (e.g. Antarctica, Baffin Bay).
Spatial resolution is 10 m, 20 m and 60 m
Systematic provisioning started in April 2016.
Temporal resolution (revisit): 5 days at equator, 2-3 days at mid-latitudes (see graphics at right)
Sentinel-2 data quality is reported monthly by ESA.
