How does the effect of shadows from either clouds or view angle affect fire detections?
Cloud shadows do not have an effect. The fire detection algorithm measures fire emissions versus background ground temperature – it does not measure sunlight. However, view angle is important. The wider the view, the larger the pixel field of view (the ground space covered). As a result, you would need a proportionately larger fire area for the same likelihood of detection for most algorithms. This necessity is incorporated into quality control reporting.
