VIIRS/JPSS1 FILDA-2 Fire Modified Combustion Efficiency Product 6-min L2 Swath 750m V002

The Visible Infrared Imaging Radiometer Suite (VIIRS) FIre Light Detection Algorithm-2 (FILDA-2) Modified Combustion Efficiency (MCE) Version 2 swath product (VJ147IMG) is produced in 6-minute orbit segments 375 meter (m) resolution from the VIIRS sensor aboard the NOAA-20 satellite. The VJ147IMG product takes advantage of the rich information that visible band observation conveys at night to assess fire combustion efficiency and enhance fire detection. It also utilizes improvements made in fire detection algorithms to detect smaller and cooler fires. The VJ147IMG product includes 83 layers containing fire detection and retrievals of Radiative Power (FRP), fire Visible Energy Fraction (VEF), and Modified Combustion Efficiency (MCE).

The Visible Infrared Imaging Radiometer Suite (VIIRS) Thermal Anomalies (VJ114) Version 2 product is produced in 6-minute temporal satellite increments (swaths) at 750 meter resolution from the VIIRS sensor located on the NOAA-20 satellite. This product is designed after the Terra and Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Thermal Anomalies and Fire data products to promote the continuity of the Earth Observation System (EOS) mission. This data product can enable users to understand the location and intensity of fire events as well as identifying thermal anomalies. The VJ114 product includes 31 science dataset variables to analyze key factors in fire detection, including atmospheric conditions (e.g., atmospheric reflectance, solar zenith angle, brightness temperature) and fuel type for the event. The fire mask variable in the VJ114 product is the primary variable and can be used to identify fires and other thermal anomalies such as volcanoes. In addition to the fire mask, brightness temperature is provided for VIIRS channels M5, M7, M11, M13, M15, and M16. Each swath of data is approximately 3,060 kilometers along track (long) and 3,060 kilometers across track (wide). The VJ114 product is also used to generate higher-level fire data products. Use of the VJ103MODLL data product is required to apply accurate geolocation information to the VJ114 Science Datasets (SDS).
