"The Global Fire Atlas of individual fire size, duration, speed and direction" Andela et al. Never before have Please zoom in to any region of interest and click on any fire to explore regional fire behavior across the globe. It impacts plant and animal habitat, air and water quality,
of even very hot fires.” The near-daily global coverage gives scientists an The data explorer tool below allows for exploration of the ignition point (red dots) and fire perimeter (black lines) shapefiles with corresponding attribute tables as well as the underlying 500 m gridded data on individual fire behavior (Table 1). The Global Fire Atlas dataset tracks the day-to-day dynamics of individual fires based on moderate resolution burned area data. For more information, read Fire Towers in the Sky: New Maps Show Annual Global Portrait of Fire and visit the MODIS Fire and Thermal Anomalies Website, Image by David Olsen, based on data provided by the MODIS Land Team, Image of the Day activity.
Data are available in easily accessible GIS-layers and can also be explored online here and a detailed description of the underlying methodology is provided by Andela et al. The fire maps show the locations of actively burning fires around the world on a monthly basis, based on observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite. life and climate. Human Presence In contrast, the 0.25° monthly layers are produced for each calendar year, with averages taken based on the fraction of burned area of each individual fire within the respective month and 0.25° grid cell. The shapefiles of ignition locations (point) and fire perimeters (polygon) contain attribute tables with summary information for each individual fire, while the underlying 500 m gridded layers reflect the day-to-day behavior of the individual fires.
In these sparsely populated high fuel-load systems fires can continuously burn as long as weather conditions are favorable. The Global Fire Atlas is a new freely available global dataset that tracks the daily dynamics of individual fires to determine the timing and location of ignitions, fire size and duration, and daily expansion, fire line length, speed, and direction of spread. Christopher Justice, of the Department of Geography at University of Maryland, The NASA earth data fire map accumulates the locations of fires detected by moderate-resolution imaging spectroradiometer (MODIS) on board the Terra and Aqua satellites over a 10-day period. During 2003 - 2016, we identified about 13.3 million individual fires globally. "The Global Fire Atlas of individual fire size, duration, speed and direction", https://glihtdata.gsfc.nasa.gov/files/fire_atlas/Fire_Atlas_user_guide.pdf, https://daac.ornl.gov/cgi-bin/dsviewer.pl?ds_id=1642, https://glihtdata.gsfc.nasa.gov/files/fire_atlas/, https://glihtdata.gsfc.nasa.gov/files/fire_atlas/large_wildfires.zip, Full dataset hosted by NASA ORNL DAAC (Distributed Active Archive Center), Full dataset hosted by NASA Goddard Space Flight Center, Sample files containing the 10 largest, longest, and fastest wildfires across each continent, Andela, N., Morton, D.C., Giglio, L., Paugam, R., Chen, Y., Hanson, S., van der Werf, G. R., Randerson, J.T. The Global Fire Atlas dataset tracks the day-to-day dynamics of individual fires based on moderate resolution burned area data. The dropdown lists in the upper left corner allow users to change the year and the underlying 500 m gridded data on individual fire behavior. In addition, we provide aggregate monthly layers at 0.25° resolution for regional and global analyses. Remote Sensing. Color ranges from red where the fire count is low to yellow where number of fires is large. Global patterns of fire velocity were reversely related to fuel loads, and the highest fire velocities typically occurred in areas of low fuel loads. "The Collection 6 MODIS burned area mapping algorithm and product". MODIS’ fire detection capabilities Fires
Location and year of the largest, longest, and fastest fires over the study period 2003-2016. Because each 500 m pixel rarely burns twice during a single fire season, this format allows for annual 500 m data layers with minimal loss of information. The satellite-based atlas includes information about more than 13 million fires. The MODIS maps demonstrate the extreme fire seasons seen this year in the US, Learn about deforestation rates and other land use practices, forest fires, forest communities, biodiversity and much more. The About Rapid Response Imagery page provides more information on usage guidelines, product quality, and algorithms for the fire location data. (2019). Latest revision: April 24th, 2019 Satellites detect fires that are not necessarily being reported. Land. The methodology and validation are presented in Andela et al. Image of the Day Interestingly, fire behavior (e.g. The data provide unique insights in the environmental conditions that give rise to the world's most extreme wildfires. "The Global Fire Atlas of individual fire size, duration, speed, and direction.".
The image above shows fires during August 1522, 2002.

Across the world, the widespread fires that The maps are a milestone in the use of satellite data for creating a Spectroradiometer (MODIS) on NASA’s Terra satellite, scientists at Goddard Space are a big step forward in satellite-based fire mapping. attract a lot of attention, but it is the smaller, more numerous fires in the Land across the entire Earth more accurately than any previous satellite sensor, and Australia, and Siberia. MODIS can detect fires August 2001August 2002 animation (2.8 MB Quicktime). While the world's largest fires occurred in more arid ecosystems, the longest fires burned for over 2 months in seasonal regions of the humid tropics and high-latitude forests. Image of the Day Data are available from 2003 to 2016 and will be updated annually while both Moderate Resolution Imaging Spectroradiometer (MODIS) instruments are operational. it has a higher temperature threshold, which means it can tell the temperature is the project’s lead scientist. speed and direction of spread) varied widely within the fire boundaries and across different days. Users can subscribe to email alerts bases on their area of interest. Data are produced in GIS file-formats (GeoTIFF and shape files) and are available as gridded 500 m global layers with corresponding vector shapefiles showing individual fire perimeters and ignition locations, as well as a monthly 0.25° aggregate product (Table 1). Remote Sensing. NASA | LANCE | Fire Information for Resource Management System provides near real-time active fire data from MODIS and VIIRS to meet the needs of firefighters, scientists and users interested in monitoring fires.
