Resource Spotlight



Wildfire is an essential process connecting terrestrial systems to the atmosphere and climate. As vegetation burns, it releases smoke, carbon, and other materials into the atmosphere. These fires also release nutrients into the soil and are an integral part of ecological succession, plant germination, and soil enhancement.

NASA's Earth Science Data Systems (ESDS) Program provides unrestricted access to data, services, and tools that enable resource managers, disaster management teams, and scientists to understand and monitor environmental conditions before a fire starts, measure the intensity and development of fires during a burn, and assess the environmental and socioeconomic impacts after a burn. Additional resources are available through NASA's Applied Sciences Wildfires program area and other agency initiatives.

The number, severity, and overall size of wildfires has increased, according to the U.S. Department of Agriculture, through contributing factors including extended drought, the build-up of fuels, past fire management strategies, invasive species targeting specific tree species, and the spread of residential communities into formerly natural areas. In 2021, 58,985 wildfires were reported across the U.S. that consumed 7,125,643 acres, according to the 2021 Annual Report by the National Interagency Coordination Center (NICC). But wildfires also have a human component, and the NICC report notes that "a total of 5,972 structures were reported destroyed by wildfires in 2021, including 3,577 residences, 2,225 minor structures, and 237 commercial/mixed residential structures. In 2021, California accounted for the highest number of structures lost in one state: 2,031 residences, 196 commercial/mixed residential structures, and 1,136 minor structures."

Along with near real-time wildfire data available through NASA's Fire Information for Resource Management System (FIRMS, described below), current U.S. wildfire statistics are available through the National Interagency Fire Center (NIFC).

Wildfires Data Pathfinder

The Wildfires Data Pathfinder directs users to NASA datasets that can aid in forecasting events, monitoring ongoing events, and assessing post-fire areas. The Data Pathfinder also provides access to tools and applications for discovering, visualizing, and working with wildfire-related resources in NASA's Earth Observing System Data and Information System (EOSDIS) collection.

Fire Information for Resource Management System (FIRMS) and FIRMS US/Canada

NASA's Fire Information for Resource Management System (FIRMS) distributes global near real-time (NRT) active fire data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS) instruments aboard Earth orbiting satellites within three hours of an observation. Active fire/hotspot data acquired by instruments aboard geostationary satellites will be added to FIRMS later in 2022. FIRMS is part of NASA's Land, Atmosphere Near real-time Capability for EOS (LANCE).

Thermal anomalies detected by MODIS or VIIRS are defined as the center of a 1 km pixel (MODIS) or a 375 m pixel (VIIRS) flagged as containing one or more fires or other thermal anomalies (such as an active volcano). Detected anomalies are updated constantly and plotted as orange (MODIS) or red (VIIRS) dots and indicate the approximate location of a potential wildfire or other thermal anomaly. Users also can sign up to receive alerts for hotspots detected in user-defined areas of interest.

FIRMS provides enhanced interactive tools for visualizing satellite imagery, active fire detections, and other NASA science products relevant to wildfire management. In addition, data (including historical data) can be downloaded in multiple geographic information system (GIS) formats.

LANCE FIRMS developers partnered with the USDA Forest Service to create FIRMS US/Canada. FIRMS US/Canada offers additional contextual layers and enhancements, including integration of U.S. and Canadian fire geospatial data and incident reports, improved classification of fires to show time since detection to better depict active fire fronts, and other information for current large fires in the U.S. and Canada. FIRMS US/Canada also provides U.S. and Canadian administrative ownership boundaries and interagency fire management boundaries, daily fire danger forecasts, and current National Weather Service fire weather watch and red flag warning areas. Near real-time data with real-time availability for selected data sources will be added to FIRMS US/Canada later in 2022.

Worldview and the Worldview Image of the Week Archive

The NASA Worldview data visualization application gives users the ability to interactively browse and view natural events as they are seen by NASA’s constellation of satellites, including wildfire data available through FIRMS. Natural event metadata used in Worldview are curated and provided by NASA's Earth Observatory Natural Event Tracker (EONET) API. Worldview uses NASA's Global Imagery Browse Services (GIBS) to retrieve imagery rapidly for interactive browsing. The Worldview Image of the Week Archive showcases a wide range of Worldview imagery and data.

Interactively Explore Wildfire Data in NASA Worldview

The Worldview map below allows you to interactively explore some of the wildfire resources available through Worldview. The example shows a list of fire events between June 7 and June 17, 2022. Clicking on an event in the Layer List or on the map allows you to see more information and related resources for that event. Clicking on a red or an orange detected thermal anomaly dot brings up vector information about a detected hotspot (you may need to zoom in to activate the vector layer). On the map, you can also change the date in the lower left corner to see how the fires have progressed over time. Click on the map to open the full version of Worldview in a new browser tab to continue the exploration by adding relevant imagery layers, setting up an animation, and much more!
