Welcome to GHRSST, the Group for High Resolution Sea Surface Temperature.
To measure sea surface temperature (SST), scientists deploy temperature sensors on satellites, drifting and moored buoys, ships, Argo floats, gliders, marine mammals, for example seals, and ocean reference stations.
In situ measurements from drifting buoys, moorings, Argo floats, and ships are commonly used to calibrate and validate the satellite-derived SST data.
SST measurements benefit a wide spectrum of operational applications, including ocean, weather, climate and seasonal monitoring/forecasting, military defense operations, validation of atmospheric models, sea turtle tracking, evaluation of coral bleaching, tourism, and commercial fisheries management (O’Carroll et al., 2019).
The Group for High Resolution SST (GHRSST) provides SST formatted products in prescribed formats (GHRSST Science Team, 2012) – Level 2 pre-processed (“L2P”) on the original swath projection, Level 3 composite (gridded with gaps) products formed using SST from either a single swath/scene (“L3U”), a single sensor but multiple swaths/scenes (“L3C”) or multiple sensors (“L3S”), and Level 4 analysed (gridded, gap-free) SST from multiple sensors/platforms (“L4”). These global and regional spatially-mapped SST products are available for research and operational applications (Beggs, 2010; Donlon et al., 2009).
We refer in this website to GHRSST formatted products because there is no ONE GHRSST product, but a wide range of SST producers worldwide that use the common GHRSST format and specifications.
These products suit different applications, and there are several web-tools available to assist a user to select an SST product, including validation sites.

We hope that we have provided sufficient guidance on our website to help you navigate through these choices.
