This image has been obtained using data retrieved by the Copernicus Sentinel-3 mission on 24 February 2021: it shows a cloud-free view of central Europe. The main objective of the Copernicus Sentinel-3 mission is to measure sea surface topography using the SRAL instrument, sea and land surface temperature using the SLSTR instrument, and ocean and land surface colour using the OLCI instrument. These three instruments aboard the two Copernicus Sentinel-3 satellite allow for accurate and reliable measurements that support ocean, environmental and climate monitoring.
