Bush and Forest Fires in Australia: 7 February 2000

 

Bush and Forest Fires in Australia

7 February 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.

The Department of Natural Resources and Environment is responsible for the management of fire prevention and suppression on public lands in Victoria. The last updated bushfire statistic of 7 February 2000 shows 1 going, 1 contained and 12 controlled fires. The locations of these fires are displayed in the statewide fire situation map below.

The Australian Bureau of Meteorology issued on 7 February 2000 an updated forecast for Northern Territory:
North of Daly Waters…
Monsoonal showers and storms developing from the east with areas of rain and locally heavy falls. Light winds at first tending moderate northerly.

South of Daly Waters…
Continuing hot. Isolated afternoon showers and storms north of Alice Springs, more widespread in the Barkly region. Moderate easterly winds, fresh and gusty during the day.

Fire Danger
Very high in the eastern Alice Springs region.

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)
http://www.rss.dola.wa.gov.au/apps/firewatch.html
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.
