Levels from 0 to 4 have been defined by the remote sensing community to describe the processing level of products. Level 0 represents raw data, while Level 4 data have had the greatest amount of processing applied. Level 2 products are retrieved environmental variables at the same resolution and location as the level 1 source data. The OSI SAF products are L2 and L3 products based on lower level products mainly provided by EUMETSAT.
