ConclusionsDiurnal cycle of fire emissions
(Africa)
from Roberts et al., 2005
• Global fire emissions still very uncertain
• Strong need for monitoring and forecasting
• Satellite products show great potential
• Products must be assessed regionally …
• … and with common measures
• Statistics for ecoregions might provide insight into reasons for discrepancies
