Copernicus Sentinel-3 provides satellite observations of ocean and land colour, sea and land surface temperature, and sea surface topography. This record focuses on imagery and ocean-colour products available through the Copernicus Data Space Ecosystem. Spatial resolution varies by instrument and product; OLCI ocean-colour products are available at approximately 300 m (full resolution) and 1,200 m (reduced resolution).

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.

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.
