Wildfires are a growing global problem. The application of Earth observation (#EO) for early remote detection of #wildfires typically offers two key approaches. First, observers can attempt to identify chemical absorption bands of interest, such as potassium, that can be indicative as precursors to wildfire. More common is the use of #ThermalImaging to look for hot spots, or specific heat profiles, in long-wavelength infrared (#LWIR) bands. Learn more: https://ilphotonics.com/fire-detectors-in-orbit/
