Where fires are burning, daily (VIIRS, Suomi-NPP)

VIIRS/NPP Thermal Anomalies and Fire Daily L3 Global 1km SIN Grid V002
biosphere NASA LPCLOUD Level 3 active HDF-EOS5
In plain English

What it measures. Daily locations of active fires and other unusually hot spots worldwide, on a 1-kilometer grid, along with how confident the detection is and how much heat each fire is giving off.

How it's made. Compiled by detecting fire signals in 750-meter VIIRS imagery from the Suomi-NPP satellite, then combining a day's worth of detections into a single gridded global snapshot.

How & where you'd use it. Helps spot and track wildfires, monitor agricultural burning, study fire patterns, and support emergency response.

Official description

The daily NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Thermal Anomalies and Fire (VNP14A1) Version 2 data product provides daily information about active fires and other thermal anomalies. The VNP14A1 data product is a global, 1 kilometer (km) gridded composite of fire pixels detected from VIIRS 750 meter (m) bands over a daily (24-hour) period. The VNP14 data products are designed after the Moderate Resolution Imaging Spectroradiometer (MODIS) Thermal Anomalies/Fire product suite. The VNP14A1 product provides a total of four Science Dataset (SDS) layers for the confidence of fire, maximum fire radiative power (FRP), quality assessment (QA), and position of fire within scan. Each data product file is provided in HDF-EOS5 format. A low resolution browse is also provided showing the fire mask layer with a color map applied in JPEG format. Known Issues * For complete information about known issues please refer to the [MODIS/VIIRS Land Quality Assessment website](https://landweb.modaps.eosdis.nasa.gov/knownissue?sensor=VIIRS).
