Measurements and Applications
|
NIRST makes use of two linear microbolometric arrays, respectively sensitive to the midwave and longwave infrared bands, to perform pushbroom scan measurements. It measures the characteristics of forest fires and other thermal events on land, such as temperature and released energy, in the thermal range from 300 to 700 K. NIRST will also measure sea surface temperatures (250 to 500 K) over selected targets to support Aquarius instrument corrections.
