Copernicus Sentinel-2 provides multispectral satellite imagery for monitoring land surfaces, vegetation, soil, water cover, inland waterways and coastal areas. The MultiSpectral Instrument (MSI) acquires data in 13 spectral bands at spatial resolutions of 10, 20 and 60 metres. Available products include Level-1C top-of-atmosphere reflectance and Level-2A atmospherically corrected surface reflectance. Data are available free of charge through the Copernicus Data Space Ecosystem.

The Harmonized Sentinel-2 MSI Level-2A (SR) collection provides wide-swath, high-resolution multispectral imagery for land and coastal monitoring. It contains Sentinel-2 Level-2A surface reflectance data, including 12 spectral bands at 10 m, 20 m and 60 m spatial resolutions. The harmonized collection adjusts newer Sentinel-2 scenes to maintain consistency with the value range of older scenes.

Landsat Collection 2 Level-2 Surface Reflectance products provide atmospherically corrected surface reflectance data derived from Landsat sensors. The products support analysis of changes in land surface conditions over time and provide a long-term record of multispectral Earth observations at 30 m spatial resolution.
