VIIRS 375m, I-Band Active Fire Product NRT (Vector Data)

Version 1NRT eng NRT
  • Abstract
    The VIIRS 375m active fire product is the latest product to be added to FIRMS. It provides data from the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor aboard the Suomi-National Polar-orbiting Partnership (S-NPP) satellite. The 375m data compliments MODIS fire detections; they both show good agreement in hotspot detection but the improved spatial resolution of the 375m data provides a greater response over fires of relatively small areas and provides improved mapping of large fire perimeters. The 375m data also has improved nighttime performance. Consequently, these data are well suited for use in support of fire management (e.g., near real-time alert systems), as well as otherscience applications requiring improved fire mapping fidelity. Recommendedreading: VIIRS 375m Active Fire Algorithm User Guide(https://earthdata.nasa.gov/files/VIIRS_375m_Users_guide_Dec15_v2.pdf)(updated December 2015).Fire Radiative Power (FRP): The 375m product does not have an FRP value at this time. It is understood that this will be an issue for some users and there are plans to add it in the near future.Other Fire products from VIIRSA complimentary VIIRS M-Band 750m active fire data product is available from the University of Maryland VIIRS Active Fire Web page(http://viirsfire.geog.umd.edu/). FIRMS has opted to distribute the 375mproduct rather than the 750m product as the increased spatial resolution and increased number of fires detected is of interest to the to thebroader fire management community.
  • Purpose
    To provide VIIRS 375m active fire locations in Near Real-Time in easy to use formats.

    Quality
    This is a near real-time (NRT) product that has undergone expedited processing to make it available within 3 hours of observation time to meet the needs of the NRT applications community. NRT data are subject to geolocation errors or reprocessing. Usually the geolocationalerrors are minimal (less than 100 meters), however, there are situations, particularly before and after spacecraft maneuvers and during space weather events, when the difference can increase up to several kilometers.
