Map Layer Information:  VIIRS IBAND Fire Detection

The VIIRS 375 m (VNP14IMGTDL_NRT) 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 joint NASA/NOAA Suomi National Polar-orbiting Partnership (SNPP) satellite. The 375 m data complements MODIS fire detections; they both show good agreement in hotspot detection but the improved spatial resolution of the 375 m data provides a greater response over fires of relatively small areas and provides improved mapping of large fire perimeters. The 375 m 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 other science applications requiring improved fire mapping fidelity.

The currency of the VIIRS data is shown by the color of the symbol on the map.

Identification of a VIIRS pixel as "fire" in this layer does not necessarily mean that the entire area represented by the pixel is on fire.

The VIIRS IBAND layer is updated every two hours. However, there may be gaps in daily coverage. If we have received no new data, the "expired" layers are not replaced. The layer is replaced as soon as we receive an updated file.

This fire location data is compiled by the USDA Forest Service Remote Sensing Applications Center in cooperation with NASA Near Real-Time Data and Imagery - Fire Information for Resource Management System.
