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

Real Time SST monitoring
A selection of plots using OSTIA data to monitor sea surface temperature can be found here.
Data visualisation
OSTIA data can be viewed interactively here.
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.
Data Access
Access to OSTIA data is available by e-mailing the MyOcean service desk.
