Global SST ensemble intercomparison

Overview

This page shows the differences between daily sea surface temperature (SST) analyses produced around the world. It is a contribution to the Group for High Resolution SST (GHRSST) (external link).

SST Ensemble Intercomparison Statistics

The median and standard deviation of daily SST analyses are displayed below. The analyses used in the statistics are listed in the table below:

NAVO K10 Global 10km SST model from Naval Oceanographic Office (NAVO) NAVO K10 information
MGDSST Merged Satellite and In-situ Data Global Daily Sea Surface Temperature (MGDSST) from Japan Meteorological Agency (JMA) MGDSST information
RSS MW Fusion Remote Sensing Systems (USA) analysis using microwave (MW) data RSS information
RSS MW+IR Fusion Remote Sensing Systems (USA) analysis using microwave (MW) and infra-red (IR) data RSS information
FNMOC Analysis generated by the Fleet Numerical Meteorology and Oceanography Centre (US) FNMOC information
GAMSSA Global Australian Multi-Sensor SST Analysis (GAMSSA) produced by the Australian Bureau of Meteorology (ABOM) GAMSSA information
DMI Analysis produced by the Danish Meteorological Institute DMI information
MUR Multiscale Ultrahigh Resolution (MUR) analysis produced by the Jet Propulsion Laboratory (JPL) MUR information
OSPO Night Analysis produced by the Office of Satellite and Product Operations (OSPO) OSPO Night information
CMC0.1 Canadian Meteorological Centre analysis with 0.1 degree resolution CMC0.1 information

The analysis grids have been homogenised by area averaging onto a 0.25° lat/lon grid prior to comparison. The data have been restricted to the OSTIA ocean mask. The sea ice data shown is derived from OSTIA. Where the OSTIA analysis indicates ice, SST values are masked out.
