Introduction
This block provides Sentinel-3 images at various processing levels. These images are acquired by the twin constellation Sentinel-3A and 3B at a revisit rate from 1 to 27 days anywhere on the globe, depending on the imaging instrument and the constellation configuration. The datasets are available starting with 2016.
