Because of its usefulness in both detecting and monitoring smoke from fires, particularly large scale fire events and pyroCbs, the S-NPP OMPS AI is now included as an overlay in NASA’s Fire Information for Resource Management System (FIRMS) application, which provides near real-time active fire/hotspot locations using satellite-derived fire information to natural resource managers.  An example for May 11 is provided in the imager image and link below:

Figure 3: Comparison of AI measurements from S-NPP (left) and NOAA-21 (right) OMPS instruments. AI products generated from N-21 have a higher spatial resolution (xxxkm10km x 10km in the nadir direction - looking straight down from the spacecraft), which is 25 times more resolute than the (50km x 50km resolution) S-NPP AI products (2km), providing a much greater level of detail for the smoke plumes.
