We are happy to announce that one more data source has been added to Sentinel Hub. Medium Resolution Imaging Spectrometer (MERIS), part of European Space Agency’s (ESA) Envisat Earth Observation (EO) Satellite, brought new dimension to Sentinel Hub browsing experience.
The polar orbiting Envisat EO Satellite was launched in 2002, with 10 instruments aboard. Weighing more than eight tons, it is the largest civilian EO mission. Since its launch, Envisat has orbited Earth more than 50,000 times and has lived twice as long as planned. The Envisat MERIS imagery enriched Sentinel Hub for more than 130,000 scenes captured during its 10 years long operation. The Envisat mission ended on April 8, 2012, following the unexpected loss of contact with the satellite.
Browse and explore Envisat MERIS scenes through EO Browser, a free satellite imagery visualisation tool with the complete archive of Sentinel-2 and Sentinel-3, ESA’s archive of Landsat 5, 7, 8, global coverage of Landsat 8, and Proba-V products reachable in one place.

The primary purpose of MERIS is for Ocean Colour Observations, and the secondary for understanding of atmospheric parameters associated with clouds, water vapour and aerosols in addition to land surface parameters, in particular vegetation processes.
MERIS consists of 15 spectral bands in the 412.5 - 900 nm range of the electromagnetic spectrum, and it allows the programmability of its spectral bands in their width and position. Full resolution data represents roughly 300 m per pixel on the ground. The instrument measures a field of view of 68.5 degrees with a swath width of 1150 km.
