This Level 2 and 3 product provides sea surface temperature at 1 km resolution over the global ocean. In addition, a quality assessment parameter is included for each pixel. The Level 2 product is produced daily and consists of global day and night coverage every 24 hours. It is used to generate the gridded Level 3 products daily and weekly for day and night conditions. a quality parameter is provided for each dataset.
( SST) is a key characteristic of El and La iña events. SSTs are monitored from ship reports, buoys and satellite imagery. [ Current SST chart
Temperature of the water of the surface layer of the sea.
Surface temperature data collected using IR satellite imagery, buoy and ship data.
The skin temperature of the sea.
temperature of the water film at the sea surface.
The temperature of the water's surface. It is measured using buoy and ship data, infrared satellite imagery, and coastal observations.
Sea surface temperature (SST) is the water temperature at the surface. In practical terms, the exact meaning of "surface" will vary according to the measurement method used. A satellite infra-red radiometer indirectly measures the temperature of a very thin layer (about 10 micrometres thick) or skin of the ocean (leading to the phrase skin temperature) representing the top millimeter; a thermometer attached to a moored or drifting buoy in the ocean would measure the temperature as a specific depth (e.g. the top 1 meter below the sea surface); the measurements routinely made from ships are often from the engine water intakes and may be at various depths in the upper 20 m of the ocean.
