Overview

This page shows the differences between daily sea surface temperature (SST) analyses and also differences between the median SST and multiyear means for the same time of year (climatology).

SST Ensemble Intercomparison Statistics

The median and standard deviation of the available daily SST analyses are displayed below. The analyses used in the statistics are OSTIA, RTG, K10, MGDSST, RSS MW, RSS MW+IR, FNMOC, NOAA AVHRR OI, CMC, ODYSSEA and GAMSSA. Where an analysis indicates sea ice, with no other SST value, a value of -1.8°C has been substituted. The analysis grids have been homogenised by area averaging onto a 0.5° lat/lon grid prior to comparison. The data have been restricted to the OSTIA ocean mask, although several analyses provide greater coverage (such as large lakes). These pages are a United Kingdom contribution to the GHRSST-PP Multi-product Ensemble (GMPE) experiment. Latest El Nino index from GMPE.
