Measurements from energy-detecting instruments on satellites provide a way to monitor vegetation health, drought, soil saturation, moisture and thermal conditions, fire risk, greenness of vegetation cover, vegetation fraction, leaf area index, start/end of the growing season, and crop and pasture productivity.
Where do these data come from?
Data and images are derived from the radiance (type and amount of energy) observed by the VIIRS instrument onboard the Soumi-NPP satellite. VIIRS stands for Visible Infrared Imaging Radiometer Suite: the instrument is on the Soumi-NPP satellite.
