Satellite Remote Sensing Monitoring
A technique for observing the Earth's surface using satellite sensors. In Arctic fire monitoring it identifies fire points through thermal anomaly detection, commonly using MODIS and VIIRS data sources.
Timeline (last 90 days)
Fire monitoring over vast Arctic regions relies on satellite remote sensing, with commonly used data sources including MODIS (spatial resolution of about 1 km) and VIIRS (about 375 m) sensors.
Satellite remote sensing is prone to missing fires smaller than the pixel scale, short-duration fires, and fire points obscured by clouds, and its limited overpass frequency makes it difficult to capture rapid changes in fire behavior.
Thermal anomaly detection can only give fire point locations and radiative power, cannot directly distinguish flaming from smoldering combustion, and certainly cannot quantify the burning depth of soil carbon.
