About

Sentinel-2A and Sentinel-2B are two identical Earth observation satellites launched by the European Space Agency (ESA) in 2015 and 2017, respectively. They are part of the Sentinel mission, which aims to provide free and open access to high-quality data for a range of applications, including land monitoring, agriculture, and forestry. The Sentinel-2 satellites are equipped with state-of-the-art multispectral imaging instruments, providing a unique combination of high spatial resolution and frequent revisit times.

Features and Benefits

  • Sentinel-2A and Sentinel-2B provide multispectral data with 13 bands in the visible and near-infrared regions. This provides valuable information for monitoring land use and land cover changes over time, as well as vegetation health and water quality.
  • The Sentinel-2 satellites provide systemic global coverage of land surfaces and coastal waters, making it a valuable tool for a range of applications, including land management, agriculture, and forestry.
  • With a revisit time of every five days (combined constellation), Sentinel-2A and Sentinel-2B provide up-to-date and accurate information for monitoring changes on the ground.
  • The Sentinel-2 satellites have a large swath width of 290km at nadir, providing broad coverage for a range of applications.
  • The Sentinel-2 data is freely available and accessible to all, making it a valuable resource for researchers, government agencies, and commercial organisations.
  • Sentinel-2A and Sentinel-2B are valuable tools for monitoring environmental changes, including deforestation, wildfire, and natural disasters.
