Operational Sea Surface Temperature and Sea Ice Analysis (OSTIA)

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 via the MyOcean viewer here. Choose "Analysed foundation sea surface temperature over the global ocean" as the Dataset. The SST anomaly to climatology and satellite biases can also be viewed 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. Click here for more information about MyOcean.

WARNING: OSTIA users still obtaining data from http://ghrsst-pp.metoffice.com/data/OSTIA should transition to the MyOcean data service described above. The feed through http://ghrsst-pp.metoffice.com/data/OSTIA will be discontinued on Jan 14th 2014. Any problems contact the OSTIA team on ml-ostia@metoffice.gov.uk

Documentation

A description of the OSTIA system can be found in the following paper: Donlon et al. 2012.
