What is the detection confidence?
A detection confidence intended to help users gauge the quality of individual hotspot/fire pixels is included in the Level 2 fire product. This confidence estimate, which ranges between 0% and 100%, is used to assign one of the three fire classes (low-confidence fire, nominal-confidence fire, or high-confidence fire) to all fire pixels within the fire mask. In the Collection 4 fire product this confidence estimate does not adequately identify highly questionable, low confidence fire pixels. Such pixels, which by design should have a confidence close to 0%, are too often assigned much higher confidence estimates of 50% or higher. This will be corrected for Collection 5.
