Sea surface temperature (or ocean surface temperature) is the temperature of ocean water close to the surface. The exact meaning of surface varies in the literature and in practice. It is usually between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface. Sea surface temperatures greatly modify air masses in the Earth's ...
The red line shows direct surface temperature measurements since 1880. [2] Global surface temperature (GST) is the average temperature of Earth's surface. More precisely, it is the weighted average of the temperatures over the ocean and land. The former is also called sea surface temperature and the latter is called surface air temperature.
Satellite temperature measurements are inferences of the temperature of the atmosphere at various altitudes as well as sea and land surface temperatures obtained from radiometric measurements by satellites. These measurements can be used to locate weather fronts, monitor the El Niño-Southern Oscillation, determine the strength of tropical ...

The sea surface skin temperature (SSTskin), or ocean skin temperature, is the temperature of the sea surface as determined through its infrared spectrum (3.7–12 μm) and represents the temperature of the sublayer of water at a depth of 10–20 μm. [1] High-resolution data of skin temperature gained by satellites in passive infrared ...
Remote sensing in oceanography is a widely used observational technique [1] which enables researchers to acquire data of a location without physically measuring at that location. Remote sensing in oceanography mostly refers to measuring properties of the ocean surface with sensors on satellites or planes, which compose an image of captured ...
A Sentinel-3 image shows true colour (left) and land temperature (right) during the 2021 Eurasia winter heat wave. SLSTR (Sea and Land Surface Temperature Radiometer) determines global sea-surface temperatures to an accuracy of better than 0.3 K (0.3 °C; 0.5 °F). It measures in nine spectral channels and two additional bands optimised for ...
Argo (oceanography) The distribution of active floats in the Argo array, colour coded by country that owns the float, as of February 2018. Argo is an international programme for researching the ocean. It uses profiling floats to observe temperature, salinity and currents. Recently it has observed bio-optical properties in the Earth's oceans.
