Bush and Forest Fires in Australia: 23 May 2000
Bush and Forest Fires in Australia
23 May 2000
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 as Australian Map Grid. 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 channel 3 on early morning (0050-0340hrs) and mid morning (0450-0630hrs) images.

(Please take into account, that this presentation represents mainly fire events from Western Australia and Northern Territories)
The Australian Bureau of Meteorology / Northern Territory Regional Office issued on 23 May 2000 for tomorrow the following fire weather forecasts for the Northern Territory Region: “Cloudy with patchy light rain overnight, mainly in the west. Light winds. Areas of cloud. Isolated showers and one or two storms along the north coast. Moderate southeast to east winds.”

Australasian Fire Authorities Council
The home page of the Australasian Fire Authorities Council coordinates the diverse range of activities of the different australian agencies concerned about fire
The firebreak newsletter provides a very extensive homepage with information about fire fighting in Australia, downloadable java scripts for calculating fire weather and various links to related sites
The Department of Natural Resources and Environment in Victoria
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.
Satellite Remote Sensing Services Department of Land Administration (DOLA)
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.
