Fire Detection Lab using GOES-8 Imagery


View images prepared for fire detection
    Visible, 3.9 um, 10.7 um, Reflectivity (+fog) products

Questions:         Which channels/products detect the fire "hot" spots?
                            Which channels/products detect the smoke?
                            What other features (cloud or surface) are detectable on the imagery?

Recall:
        Reflectivity product during the day:
                3.9 um (emitted + reflected energy) - 10.7 um (emitted energy)
                Fires appear as bright white spots

Fog product during the night:
          Temperature at 10.7 um (emitted energy) - Temperature at 3.9 um (emitted energy)
        Fires are warmer at 3.9 um than at 10.7 um and will give a negative temperature difference
        The way the color table is set up, the fires will appear as dark black spots.
