Product Types and Processing Levels
SENTINEL-1 data products acquired in SM, IW and EW mode which are generated by the PDGS operationally are distributed at three levels of processing.
Level-1 products can be one of two product types - either Single Look Complex (SLC) or Ground Range Detected (GRD). Level-2 Ocean (OCN) products can have different components available depending on the acquisition mode.
Products are designated based on their acquisition mode, product type and in the case of Level-1 GRD also its resolution.
All products are processed directly from the Level-0 product. Each mode can potentially generate Level-1 SLC, Level-1 GRD and Level-2 Ocean products. For WV mode, the Level-0 and Level-1 products are not distributed.
Level-2 OWS component is not available from the TOPSAR modes.
