The OSTIA system produces a high resolution analysis of the current sea surface temperature (SST) for the global ocean.

The OSTIA system
OSTIA uses satellite data provided by the GHRSST project,
together with in-situ observations to determine the sea surface
temperature. The analysis is performed using a variant of optimal interpolation (OI) described by Martin et al., 2007.
The analysis is produced daily at a resolution of 1/20° (approx. 5km). OSTIA data is provided in
GHRSST netCDF format every day.
Access to OSTIA data is available by e-mailing the MyOcean service desk.
