ATSR continuity beyond 2011
Summary
• Timing and location of fires is well known. Long timeseries (WFA, TRMM) as well as improved capabilities from new sensors (MODIS)
• Improved interannual burned area products will soon be released (GLOBCARBON, GFEDv2) ~monthly/10km resolution
• Better knowledge on diurnal cycle (ATSR, TRMM, 4 MODIS, GOES, MSG) overpasses need to be integrated globally
• Emissions from savanna and boreal regions are becoming better constrained. Peat issues in boreal region and Indonesia
• Requirements for fire/feedback from users:emission products? NRT? Diurnal Cycle?
