Tap a week to see the detections behind it.
A detection is a heat signal seen from space, not burned area or a count of separate fires.
November vs a usual year
Weeks of 26 Oct – 8 Nov, compared with the same weeks of every year since 2001
Raw satellite data would say 44.5× the usual, because it joins MODIS and VIIRS as they are and VIIRS sees far more small fires. Corrected, it is 10.6×.
