 "sst")
The temperature at the surface of the ocean (SST) is an important physical property that can be measured quite easily from Earth Observation satellites. SST has a strong influence on the exchange of heat, momentum, water and gases beteen the ocean and the atmosphere. Knowledge of the geographical distribution of SST and its variation with time is therefore essential for predicting the dynamical behaviour of the atmosphere and the ocean. SST is also an important indicator of climate and climate change, giving us a finger on the pulse of the planet itself. Climate quality sea surface temperatures are needed on an operational basis to develop better predication of climate change.
The CERSAT is a major center for the delivery of sea surface temperature in teh frame of several international projects (such as Medspiration, Mersea or GODAE/GHRSST-PP), and in partnership with other european agencies such as Météo-France/CMS, ESA or the EUMETSAT Ocean and Sea-ice SAF (SAF O&SI).
The sea surface temperature products delivered at CERSAT include both swath data (observations along the satellite track) and gap-free gridded maps obtained from the merging of all available sensors using geostatistical methodologies. Some of these data are produced by external agencies, delivered and archived by CERSAT in the frame of various projects or partnerships.
