Minimize Sea Surface Temperature (GHRSST)

The Group for High Resolution Sea Surface Temperature (GHRSST) sea surface temperature is provided in the SL_2_WST product, composed of one measurements file and no annotation files.

This file conforms to the 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 which provide a context for the SST fields.
