Recent Enhancements of the NOAA VIIRS Active Fire Product Suite

Currently there are four operational or systematically generated experimental daytime/nighttime active fire products from the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Joint Polar Satellite System (JPSS) series. The heritage 750m M-band product is produced operationally for both the Suomi National Polar-orbiting Partnership (NPP) and the NOAA-20 satellites within NOAA's Suomi NPP Data Exploitation (NDE) System. The experimental 375m I/M-band product is also generated systematically for both satellites at NOAA/ NESDIS Center for Satellite Applications and Research (STAR) for evaluation and user impact assessment. The two-satellite constellation allows for better coverage near the peak of the diurnal cycle of fire activity in the early afternoon. The 50-minute, half-orbit separation between the Suomi NPP and NOAA-20 overpasses also enables the observation of short-term variations of fire activity. This presentation will include quantitative results of intercomparisons between compatible products from Suomi NPP and NOAA-20 to demonstrate continuity and consistency. We will also present results of assessments of the relative performance of the 750m and 375m products through specific examples of fire events and statistical analysis of detection performance. Finally, impacts of product improvements and two-satellite coverage on key applications will be demonstrated, including early detection and improved input into smoke emission modeling and monitoring systems.
