AATSR takes the temperature of the sea (and the forests)

The AATSR radiometer measures the radiation emitted by the Earth’s surface and the oceans in both the visible and infrared regions

The AATSR radiometer measures the radiation emitted by the Earth’s surface and the oceans in both the visible and infrared regions, enabling it to accurately determine temperatures to within 0.3°C. ESA has been providing information on sea temperatures in near-real time for a number of years – a key parameter for climate researchers when compiled over a period of several years. Envisat also benefits the fishing industry by providing data gathered by the MERIS imaging spectrometer which shows the distribution of phytoplankton.

Each year, more than 50 million hectares of forest – an area one-and-a-half times the size of Germany – burn worldwide. These fires have a significant impact on aspects such as the atmosphere and land use. The AATSR detects fires by measuring the infrared radiation they emit. This data is compiled in the World Fire Atlas, which maps all fires which exceed a certain minimum scope in near-real time.

This data is used by landscape ecologists as well as climate researchers and meteorologists. It is also tremendously useful for firefighters – a benefit that really came to the fore during the devastating fires that occurred around Moscow in 2010.
