The SLSTR Level-2 product is composed of three different packets, depending on processing parameters. A switch, defined for each Level-2 processing step, indicates if the associated product has to be generated.
As for the SLSTR Level-1 product, these three packages are composed of one information package map, also called the manifest, and several measurement and annotation data files (between 2 and 21 files depending on the package).
The manifest file is in XML format and gathers general information concerning product and processing.
The measurement and annotation data files are in netCDF 4 format, and include dimensions, variables and associated attributes. The included parameters are provided only on the 1 km grid, indexed by their along and across track indices.
For measurement files:
Annotation files are generated from the annotation files included in the SL_1RBT package and their format is identical to the files in the Level-1 packet.
Note that SL_2_WCT is an internal packet and is only used internally for normal processing reasons. It is not made available to users.
