20. Institute for Environment and Sustainability Global Vegetation Monitoring Unit Algorithm Performance Surface area accuracy of burn scars compared to TM data Sampling grid of 15x15 km, regression line, R 2, little effect due to the low resolution bias UTL Europe R 2 = 0.71 UTL AfricaR 2 = 0.4 – 0.99 (site dependent) CNRR 2 = 0.6 Per pixel confusion matrix using TM data CNR OA = 82.3% – 87% (C. Africa) Overall (OA), omission (OM) and commission (COM) map accuracies determined IFIR 2 = 0.89* JRC (Stroppiana)COM = 36% (Australian tropical savannas) * errors in burnt area mapping reported to be less than 15% Burnt surface area statistics compared to inventories/fire surveys CCRSOM = 15.5% (2000)** ** OM in Canada in 1998 = 23%, 1999 = 11%. OM in the USA in 2000 = 6.6% Work in progress: UOE/UTL and JRC(Boschetti) Per pixel confusion matrix using a visual classification of 1km data

21. Institute for Environment and Sustainability Global Vegetation Monitoring Unit Next Steps oFeedback on  version -> end November oRegional assessment of the global product Using TM scenes not previously used for regional assessment oProcessing chain -> ESA (Globcarbon 98-03) oUse Global Fire Analysis GIS Modules (JRC) oStrengthen our collaboration with: Atmospheric modelers: ACE-ASIA (2001) - West Africa Monsoon (WAM) (2003) Contribution to the EDGAR emission database Land cover change modelers: Land Use – Land Cover Change (LUCC) project of the IGBP Land resource managers

22. Institute for Environment and Sustainability Global Vegetation Monitoring Unit Conclusions oA global ‘high resolution’ map of areas burnt from a single source of information oThe methods used are fully documented which allows: (i) Repeatability and (ii) Evaluation from the users. oA similar multi-annual dataset (1998-2003) will be produced: By ESA (with co-operation from the JRC) in the context of the GLOBCARBON initiative.
