For example, a fire must have an active area ≥ 100m 2 to enable detection by a satellite pixel with an effective resolution of 1km. With that being said, traditional satellite fire detection algorithms currently used with the MODIS, VIIRS and GOES fire products begin to respond to active fires occupying a relatively small fraction (≥ 0.01 %) of the pixel footprint (assuming an average fire temperature of ≥ 800 K). Fire detection is largely a function of spatial resolution, with coarser data sets typically requiring larger and/or more intense fires for a successful detection compared to higher spatial resolution ones that can resolve smaller and/or less intense fires. There isn’t an absolute size above which one can expect a fire detection from satellites.
