3. GLM – Geostationary Lightning Mapper
GLM detects lighting by comparing the radiance background at nm – O(l) every 2 ms (“500 frames/second”).
CCD pixels that exceeds a background threshold are identified as a lightning event.
Lightning events are grouped into groups by a space/time criteria
Groups are equivalent to lightning strokes.
Groups are grouped into flashes (several strokes)
Group a
Group b
time
height
... etc .
