Sea Surface Temperature

The sections below contain information on the SST data types; including output attributes, advice on quality and purpose of the data. Click on the pictures for links to the data.

SST provides a major input to weather due to the strong interaction between SST and the atmosphere. As weather patterns change due to the long-term changes in SST, continuous monitoring of SST by satellite is necessary in order to better understand the reasons for changes in the weather patterns and to model future changes in climate, as well as to predict and monitor impacts on the population due to flooding, droughts, etc. The latest version of the ATSR SST time series is shown on the ESA SST CCI website (see
