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.
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.
Wildfire season in the Pantanal generally begins in July and peaks in August and September. Low rainfall amounts have caused the wildfire season to start earlier than usual. The image on the left (A side) is a true-color corrected reflectance image overlaid with the VIIRS fires and thermal anomalies layer, with detected hotspots shown as red dots.
Wildfires Data Pathfinder - Find Data. 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. Many factors contribute to a fire’s ...
FRP estimates are provided for active fire data from MODIS, VIIRS and geostationary sensors used in FIRMS. Sensor spatial resolution, saturation temperature of thermal bands, satellite view zenith angle, time of satellite observation, etc. can affect the accuracy and variability of FRP estimates.
24 juin 2024 · Jun 24, 2024. NASA’s Fire Information for Resource Management System (FIRMS) distributes near real-time (NRT) active fire data within 3 hours of an observation by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Aqua and Terra satellites and the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the joint NASA ...
Somewhere on Earth a wildfire is burning. Wildfires are an inescapable part of living on a planet forged in fire. In the United States, an average of 69,020 wildfires (about 85% of which are human-caused, according to the National Park Service) burn an average of 6.63 million acres each year, based on data from the past 10-years compiled by the National Interagency Fire Center
