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

Thank you
