Sea Surface Temperature
About the SLSTR
The dual view, nine-channel Sea and Land Surface Temperature Radiometer (SLSTR) on board Sentinel-3 will have a resolution of 500 m in the visible and shortwave infrared and 1 km in the thermal infrared and include two channels optimised for fire monitoring.
It will continue and further improve the sea surface temperature record collected by the AATSR instruments flown on ERS and Envisat satellites. The aim is to collect highly accurate measurements to provide a reference dataset for other sea surface temperature missions on other satellites.
The design of SLSTR is improved from the previous AATSR instruments to include a wider swath of 1400 km in the nadir view and 740 km in the dual view.
As well as monitoring SST the instrument will also monitor sea and land ice temperature, atmospheric aerosols and cloud properties and fires (both over land and for ocean gas flares).
