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, …

2022年11月16日 · The NASA data that Davies, Ichoku, Rasolohery, and many others use to track and study wildfire provide critical information they need to determine what blazes mean for African communities. Understanding the data can certainly be complex and nuanced at times, such as when viewing hundreds of tiny fire points on a world map.

2024年11月8日 · The features of the Advanced mode support wildfire practitioners and emergency response personnel who require additional information and context to inform active fire management and tactical wildfire response (including the ability to refine the active fire detection temporal search range to hourly and sub-daily [+10 minute] increments).

View a list of fire attribute fields for NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS).

Many of those products are available within hours of being acquired—essentially showing the entire Earth as it looks "right now". This supports time-critical applications, such as wildfire management, air quality measurements, and flood monitoring, as well …

NASA's Moderate Resolution Imaging Spectroradiometer continually collects data in 36 spectral channels with global coverage every 1 to 2 days.

NASA's VIIRS collects visible and infrared imagery along with global observations of Earth’s land, atmosphere, cryosphere, and ocean.
