Bush and Forest Fires in Australia: 20 January 1999
Bush and Forest Fires in Australia
20 January 1999
The Satellite Remote Sensing Services Department of Land Administration (DOLA) routinely evaluates the NOAA AVHRR satellite sensor to detect and locate vegetation fires and high-temperature events. In Australia hot events depicted by the satellite can represent wildfires or prescribed fires as well as industrial activities (e.g., gas flares, smelters) and hot surfaces (e.g., rocks heated by solar radiation during the daytime overpasses of the satellite). Thus, DOLA displays two products of hot spot maps: the automatically generated high-temperature event maps (which include false alarms) and the manually generated fire maps. All hotspot locations are geo-referenced and where required AMG. On some days up to four NOAA-AVHRR passes are used to identify hot events.
The manual method (human operator) provides greater accuracy however it takes longer. Thus, the issue of the manually generated fire maps is delayed (not real-time). Hot spots are located using NOAA-AVHRR channels 2 and 3 on early morning (0050-0340hrs) and mid morning (0450-0630hrs) images.

The last update of 20 January shows several fire events. In the future updates of Australian fire events the GFMC in collaboration with DOLA, will overlay the fire event information on a composite Australian NOAA map or on a vegetation cover map. Please re-visit us later!
The Australian Bureau of Meteorology issued high to very high fire danger for almost all of South Australia, in the hot spot area of western Australia extreme fire danger is issued for today. For the up-to-date fire weather information of the Australian Bureau of Meteorology refer to http://www.bom.gov.au/weather/
Several small grass and brush fires are recorded by the South Australian Country Fire Service ranging from 5 ha to100 ha. For detailed reports refer to the South Australian Country Fire Authorities at http://www.cfs.org.au/cfs/frames2.html
The Department of Natural Resources and Environment in Victoria reports several small wildfires, for detailed information on the current status refer to http://www.nre.vic.gov.au/fires/index.htm

The Department of Natural Resources and Environment in Victoria offers a very comprehensive web site with information on fire management. In their web site current reports are provided with statistics on the fire season. Extensive background information is included along with several links to related web sites.

The Satellite Remote Sensing Services (SRSS) of the Department of Land Administration provides near real time hot spot detection and burned scar mapping for western Australia. In the Firewatch project the SRSS detects hotspots throughout Western Australia using the thermal channel of the NOAA AVHRR sensor on a daily basis.
