VIIRS fire detections

The Visible Infrared Imaging Radiometer Suite (VIIRS) sensor was launched aboard the Suomi National Polar-orbiting Partnership (NPP) satellite on October 28th, 2011 and on January 18th, 2012 cooler doors for the thermal sensor were opened. Within hours data were being retrieved and fire detections produced. The 5 minute swath quicklooks presented here highlight recent fire detections superimposed on RGB images (bands 5-4-3). The VIIRS active fire product was released to the public on October 22nd, 2012 as beta quality back to April 2nd, 2012. On October 23rd, 2013 VIIRS AF data were declared provisional back to October 16th, 2012. Please refer to the FAQ page to read the definitions of beta and provisional data.

    photos/NPP_VIIRS_20140116_202931_203511_photo.png

    The Colby fire started early on the morning of January 16th on the outskirts of Glendora, California. VIIRS captured a clear observtion of the fire at approximately 12:30pm, local time. In the RGB image below, created from the moderate resolution (M-band, 750m) 5-4-3 channels, a smoke plume can be seen drifting West over the Los Angeles metro area. As of January 19th the fire had burned 1900 acres and destroyed 6 homes. Investigators have arrested 3 men suspected with starting an illegal campfire which escaped and caused the conflagration.

  • Still going - the Rim fire: September 9th, 2013

    photos/NPP_VIIRS_20130909_205050_205630_photo.png

    Started on August 17th, the Rim fire has now burned more than 250,000 acres (>100 ha) and cost over $100 million. Firefighters made great progress over the past several weeks to bring the fire to 80% containment, but hot, dry conditions over the past number of days have resulted in something of a stalemate to increasing containment. Conditions yesterday, September 9th, were ripe for fire activity, including upslope drafts, low humidity, high temperatures, and an unstable atmosphere. The above VIIRS image (around 1pm local time) shows detections and related smoke plumes from the Rim fire, as well as the Morgan fire outside San Francisco and the Clover fire near Happy Valley. These two newer fires have also been active, owing to the same weather and fuel conditions and rapid growth has been observed (for example the Morgan fire doubled in a day).

  • More fires across the Southwest: June 19th, 2013

    photos/NPP_VIIRS_20130619_194341_194922_photo.png

    As some fires are contained new ones pop up and several older fires increase in size. Nearly 600 firefighters are battling the Doce fire in the Prescott National Forest, Arizona, which started Tuesday, June 18th and has burned about 7,500 acres so far. The Silver fire in New Mexico, which in this image can be seen as the southern of two fires with a large column of smoke eminating from it, had a 22% increase in fire growth yesterday to over 30,000 acres. The West Fort Complex near Pagosa Springs, Colorado, is the northern of two fires with a large column of smoke obvious in this image. Made up of two fires which joined June 16th, the West Fork and Windy Pass, this complex is burning in rugged terrain and was nearing 9,000 acres yesterday, a 155% increase from the previous day. Another Arizona fire is the smaller Creek firein the southeastern portion of the state.

    photos/NPP_VIIRS_20120919_200420_201000_photo.png

    In a summer that has seen near record fire activity no western state has gone unburned. In this VIIRS image, observed around 1pm local time, fires from Washington to Idaho are clearly present. In particular, the large Table Mountain complex in Washington is evident by the huge smoke plume drifting east from the fire. The Trinity Complex and other fire incidents are clear to the east in Idaho as well.

  • California and Oregon fires: July 9th, 2012

    photos/NPP_VIIRS_20120709_205222_205802_photo.png

The Mill Fire, on the Mendocino National Forest in California, has grown rapidly in recent days due to hot, dry conditions. As of July 10th, it had burnt nearly 13,000 acres and was 60% contained. To the northeast of the Mill Fire is a large cluster of fire detections associated with the Long Draw fire near Basque, Oregon. Started by lightning on July 8th, the fire (as of July 10th) has already consumed 290,000 acres and currently is listed with a 0% containment status. Finally, to the northwest, a smaller fire complex in Oregon (45,000 acres), the Miller Homestead fire, was also detected by VIIRS.

    photos/NPP_VIIRS_20120609_201405_201945_photo.png

    Large, wind-driven fire complexes continue to grow in the SW United States. New Mexico, in particular, has 4 large fires with two categorized as "type 1" incidents; the most robust category, calling state and national-level resources and expertise. The Whitewater-Baldy fire in western New Mexico has already set a state record for burned area (278,039 acres as of June 11th) and can be recognized by the circular distribution of fire pixels near the center of the swath. To the east, with a large plume of smoke extending into Texas, is the IMT1 Little Bear fire. The only other current IMT1 fire in the U.S. can be near the top of this image, the High Park fire, burning in northern Colorado.

    photos/NPP_VIIRS_20120608_115347_115928_photo.png

    Fires routinely burn across central-southern Africa this time of year as evident by the number of detections made by NPP VIIRS in this 5 minute swath. Fires, typically used for renewing pasture growth, removing crop residue, and driving pests, and game, is tightly coupled between humans and the savanna ecology. The fire season will continue to grow in fire frequency while shifting east and south, peaking between late-July and mid-September before shifting Northern Africa.

The Punjab region is a highly productive agricultural area of Asia, as well as the world, and thus it could be assumed, given the time of year, these fires are associated with farming, and wheat harvest in particular (see Vadrevu et al., 2011).

    VIIRS spotted many fires along the Russian-Kazakhstan border (eastern portion of the swath) at around 0920 UTC. Although purely anecdotal, there appears (visually) to be a connection between the lack of cloud cover and fire activity, with what could be described as a demarcation of clouds and fires. That said, despite cloud cover to the west, many detections are still apparent in this 5 minute swath.
