About GHRSST
JAXA provides near-real-time data Sea Surface Temperature (SST) retrievals from several passive microwave imagers as a contribution to the Group for High Resolution SST (GHRSST).
Those SST products are produced at Earth Observation Research Center (EORC) of Japan Aerospace Exploration Agency (JAXA).
All SST products are in GDS format defined by GHRSST, and available as L2P (swath grid) and L3C (daily grid) products.
