The SLSTR Level-2 WST product respects the Group for High Resolution Sea Surface Temperature (GHRSST) L2P specification, and includes a single SST field derived from the best performing single-coefficient SST field in any given part of the swath, plus a number of supporting data fields providing context for the SST fields.
Each SST, previously generated during the SLSTR Level-2 algorithm or contained in the Level-2 WCT product, is atmospherically smoothed. The "best" product for the local conditions is then forwarded to the output field.
All the variables are gathered in one measurement file, called the 1 km L2P SST measurement dataset, generated on a wide 1 km measurement grid.
This file, indexed by across track and along track dimensions and by reference time, provides for each thermal SLSTR channel:
