Read More. A wildfire is an unplanned fire that burns in a natural area such as a forest, grassland, or prairie. Wildfires are often caused by human activity or a natural phenomenon such as lightning, and they can happen at any time or anywhere. In 50% of wildfires recorded, it is not known how they started.
Wildfires. 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.
Wildfires. NASA's wildfire data enable users to monitor conditions before a fire starts, track them once they do, and assess their effects after a burn. 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.
The Fire Information for Resource Management System (FIRMS) enables access to global near real-time satellite imagery, active fire/hotspots, and related products to identify the location, extent, and intensity of wildfire activity. FIRMS tools and applications provide geospatial data, products, and services to support the broader fire ...
Fire Information for Resource Management System (FIRMS) The Fire Information for Resource Management System (FIRMS) provides access, with minimal delay, to satellite imagery, active fire/hotspots, and related products to identify the location, extent, and intensity of wildfire activity. FIRMS tools and applications provide geospatial data ...
Wildfires Data Pathfinder. Along with their destructive power, naturally-occurring wildfires are a vital component of forest growth, ecological succession, and soil nutrient enhancement. NASA provides datasets and tools for assessing and managing wildfires before, during, and after an event. This Data Pathfinder is designed to help guide you ...
Active Fire Data. Download active fire products from the Moderate Resolution Imaging Spectroradiometer (MODIS) (MCD14DL) and Visible Infrared Imaging Radiometer Suite (VIIRS) 375 m (VNP14IMGTDL_NRT, VJ114IMGTDL_NRT, and VJ214IMGTDL_NRT) for the last 24 and 48 hours and for the last 7 days in shapefile, KML, WMS, or text file formats.
Nov 15, 2022. This FIRMS map of Africa from January 31, 2022, shows the Sahel region saturated with fire points, giving the appearance that a large area of the continent is burning. Most of the red dots are in fact small agricultural fires detected by the VIIRS and MODIS sensors.The need to make the dots visible on the map means they cover more ...
How do I interpret/use wildfire perimeter data in the context of satellite active fire detection data? Wildfire perimeters for individual fires are typically updated once daily using relatively large scale data (airborne infrared flights, airborne or terrestrial GPS, etc.), but may be updated more or less frequently in particular circumstances ...
