We welcome your feedback. ARAs issue these Special Smoke Statements (also known as Smoke Outlooks) for areas where smoke from wildfires may be of concern and they have been deployed. Areas of smoke are analyzed and added to the analysis during daylight hours as visible satellite imagery becomes available. Development work was done through an agreement with the University of Washington’s School of Environmental and Forest Sciences. Real-time air quality monitoring data is preliminary and should only be used for informational purposes, not for regulatory or attainment decisions. Be Prepared! Unless otherwise noted, the images linked from this page are located on servers at the Satellite Products and Services Division (SPSD) of the National Environmental Satellite, Data, and Information Service (NESDIS). In addition, the Fire and Smoke Map features fire location, basic fire information (if available), and smoke plume information. Air Quality (PM2.5) Layers: Note that the information on fire position should be used as general guidance and for strategic planning, not for tactical decisions, such as the activation of a response to fight these fires and evacuation efforts, without other information to corroborate the fire's existence and location. You may even see this type of difference when comparing two nearby sensors. Wildfire smoke can affect your health in many ways, but there are a number of different steps you can take to help protect yourself -- ranging from limiting outdoor activities to wearing masks to filtering indoor air via air conditioning or HEPA filters. "Dryland ecosystems cover over 40% of the Earth's surface, and are highly heterogeneous systems dependent upon rainfall and temperature. Please visit Technical Approaches for the Sensor Data on the AirNow Fire and Smoke Map to view a series of video segments providing detailed information on key features of the Fire and Smoke map, how it compares to other data sources, and how the air sensor data is processed and presented using the extended U.S.-wide correction equation, along with links to additional resources. This dissertation presents the potential of small unmanned aircrafts systems (sUAS) to provide affordable, on-demand monitoring of wildland fire effects at a much finer spatial resolution than is possible with the current approaches using ...
