Australian AVHRR-derivedburnt area map :1997 to 2003
3 major climate / fire regions of Australia(Myers et al. 2004)
Wet-dry tropical savannas
End of Wet Season Fuel Loads Early Dry Season ACB
Dry Season FiresLate Dry Season Extensive andIntensive Wildfires
Semi-arid and arid interiorExtensive sandplains and dunefields Dry rivers and open shrublands
Complex topography Infrequent large fires
Southern Temperate ZoneCoastal and Urban areas Mixed Land Use and WUI
Forests and Shrublands
Destructive Fires
Australian burnt area mapping validation sites
2002 AVHRR-derived burnt areas
7 sites used in initial 2002 validation analysis
Australian Validation Network 2005 Program (1)
• Second phase of 2002 analysis– Improved spatial and temporal representativeness
• Incorporate all 11 validation sites• Assess seasonal robustness
– Check areas of uncertainty in global dataset• Reporting schedule
– Contribute to 2002 report– Summary report and one-page flyer– Website of site characteristics, process and results– Contribute to qualitative product performance
reporting metrics (concept from SAFNet)
Australian Validation Network 2005 Program (2)
• 2004/2005 Second Validation Exercise– Minimum of 6 validation sites
