Along-Track Scanning Radiometer (ATSR) microwave sounder is a satellite-borne instrument designed to measure land and ocean surface temperatures.
This article is written at a definitional level only. Authors wishing to expand this entry are inivited to expand the present treatment, which additions will be peer reviewed prior to publication of any expansion.
The ATSR is a passive two-channel radiometer that scans the near-infrared and middle-infrared bands with a spatial resolution of one kilometer by one kilometer and a swath width of 500 kilometers (km). It views the Earth from an orbit of about 800 km and can measure ocean temperature to within 0.3 degrees C. The ATSR can be used to detect exceptional local incidents, large scale changes, and general trends in the Earth’s climate.
