2024年7月3日 · Wildfire smoke is a mixture of air pollutants of which particulate matter (PM) is the principal public health threat. PM 2.5 from wildfire smoke is associated with premature deaths in the general population, and can cause and exacerbate diseases of the lungs, heart, brain/nervous system, skin, gut, kidney, eyes, nose and liver.

5 天之前 · 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.

5 天之前 · Fires can be set naturally, such as by lightning, or by humans, whether intentionally or accidentally. Fire is often thought of as a menace and detriment to life, but in some ecosystems it is necessary to maintain the equilibrium, for example, some plants only release seeds under high temperatures that can only be achieved by fire, fires can also clear undergrowth and brush to …

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, …

To access active fire/hotspot data, maps, and alerts, the Fire Information for Resource Management System provides access, with minimal delay, to data and imagery that helps users identify the location, extent, and intensity of wildfire activity. Download LANCE NRT data from the following instruments and platforms:

5 天之前 · Working in conjunction with specially designed firefighting aircraft, these wildfire-trained crews suppress flames, construct firelines, and extinguish flames and areas of heat to protect resources and natural wilderness. Wildfire suppression also addresses the issues of the wildland-urban interface, where populated areas border with wildland ...

2025年4月9日 · The course, "Introduction to NASA Earth Observations and Tools for Wildfire Monitoring and Management," focuses on the multiple sources of time-sensitive satellite imagery and derived data products that can be found on the agency's Fire Information for Resource Management System website. FIRMS features a dynamic mapping interface to visualize ...

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).

2025年4月18日 · In their paper "Wildfire severity and vegetation recovery drive post-fire evapotranspiration in a southwestern pine-oak forest, Arizona, USA," published in Remote Sensing in Ecology and Conservation, Poulos and others (2021) looked at examining post-fire physiological responses of vegetation by combining field vegetation data with remotely ...

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 …
