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:

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.
