Data

The Fire Event Data Suite (FEDS) algorithm (Chen et al., 2022) uses an alpha shape approach to estimate the perimeter and properties of ongoing fire events every 12 hours, based on Visible Infrared Imaging Radiometer Suite (VIIRS) 375 m active fire detections.

A detailed overview of the FEDS algorithm and fire tracking data can be found in the Data Overview section.

Available Datasets

FEDS data are available in Near Real Time (NRT) over CONUS and Canada. Static FEDS or FEDS-like outputs associated with peer-reviewed publications are also available. Navigate to a section using the left menu bar for more detailed dataset descriptions and data access.

Near Real Time (NRT) FEDS

• Available within approximately four hours of each VIIRS overpass for the Continental United States (CONUS) and Canada.

Published Datasets

• FEDS and FEDS-like fire tracking datasets for a particular region and time span. Each dataset is associated with one or more scientific publications, where more information about that particular dataset can be found.
