NOAA/NASA’s Suomi NPP satellite captured another startling image of the August Complex of fires that has grown to over 1,000,000 acres burned (1,006,140 acres total) and because of that grim milestone the complex has been dubbed a “gigafire.” The August Complex is only 58% contained. Inciweb reports that: “In the northeast zone, active behavior continues. Structures in Hidden Valley, Trinity Pines/Post Mountain, Wildwood and Platina are threatened by fire spread. Short range spotting and fire spread toward Hidden Valley has increased potential for impact to structures.”
Inciweb reports the following weather concerns for this fires: “Hot and dry conditions persist. Smoke remains very thick in the lower valleys with visibility reduced under a mile. Temperatures will be 88-93 in the valleys and 75 to 80 in the higher elevations. The humidity will be 10-15% with 4-8 mph wind.”
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. 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 has a fleet of Earth-observing instruments, many of which contribute to our understanding of fire in the Earth system. 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’s Earth Observing System Data and Information System (EOSDIS) Worldview application provides the capability to interactively browse over 700 global, full-resolution satellite imagery layers and then download the underlying data. Many of the available imagery layers are updated within three hours of observation, essentially showing the entire Earth as it looks “right now.” Actively burning fires, detected by thermal bands, are shown as red points.

Democratic norms are being stress-tested all over the world, and the past few years have thrown up all kinds of questions we didn't know needed clarifying – how long is too long for a parliamentary prorogation? How far should politicians be allowed to intervene in court cases? To monitor these issues as closely as we have in the past we need your support, so please consider donating to The Climax News Room.
