Satellites in orbit around the poles provide observations of the entire planet several times per day, whereas satellites in a geostationary orbit provide coarse-resolution imagery of fires, smoke and clouds every five to 15 minutes. NASA has a fleet of Earth-observing instruments, many of which contribute to our understanding of fire in the Earth system. Together, NASA instruments detect actively burning fires, track the transport of smoke from fires, provide information for fire management, and map the extent of changes to ecosystems, based on the extent and severity of burn scars. NASA’s satellite instruments are often the first to detect wildfires burning in remote regions, and the locations of new fires are sent directly to land managers worldwide within hours of the satellite overpass. The Aerosol Index layer is useful for identifying and tracking the long-range transport of volcanic ash from volcanic eruptions, smoke from wildfires or biomass burning events and dust from desert dust storms, even tracking over clouds and areas of snow and ice.” In this image deep red areas can be seen in California but can also be seen as far east as Minnesota meaning the heavy aerosols do not necessarily diminish as they travel on the air currents. According to NASA Worldview: “The Aerosol Index is a unitless range from =5.00, where 5.0 indicates heavy concentrations of aerosols that could reduce visibility or impact human health. The aerosol index provides information about the presence of particles in the air. This aerosol image below shows not only California being affected by the heavy smoke as seen in the visible image above, but the smoke has traveled across much of the United States affecting areas from California all the way to Minnesota and Nebraska and air currents will undoubtedly carry the smoke across the entire U.S. More insidious than the fires is the smoke that rises from the landscape. The data is updated every month.NASA Worldview, Earth Observing System Data and Information System (EOSDIS).

SMOKE: Southeastern United States - Although seasonal burning activity was seen in the SE corner of the U.S., specifically Alabama, Georgia, and Florida, only a few smoke plumes were seen on satellite imagery due to the system over the CONUS.
