Wildfire smoke is a mixture of hazardous air pollutants, such PM 2.5, NO 2, ozone, aromatic hydrocarbons, or lead. In addition to contaminating the air with toxic pollutants, wildfires also simultaneously impact the climate by releasing large quantities of carbon dioxide and other greenhouse gases into the atmosphere.
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, products, and services to support the broader fire ...
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.
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.
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.
13 de jun. de 2024 · 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.
16 de jun. de 2023 · If burns are minor, keep the burned area in contact with cool running water for 20–30 minutes. If burns are severe, do not attempt to remove clothing stuck to the burn. Cover the person with a clean, dry cloth or blanket to reduce heat loss and help prevent shock. Do not apply ice, pastes or oils to the burned area.

Many fires were ignited by lightning strikes in areas stricken by drought. Smoke from these wildfires is likely to move south into the U.S., particularly over the Northwest and Midwest, according to the Washington Post, joining smoke from fires already burning in Washington and Oregon. Light smoke from Canadian fires is forecast to drift into ...
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 ...
