Fossil Fuel and Biomass Burning Black Carbon Emissions from the Global Emissions Inventory Activity (GEIA)

In addition seasonality as estimated by satellite observations are used to modify the seasonality of vegetation fires in Africa. This modification is discussed in Cooke et al. (1996) The modifications to the Hao et al. data is as follows: 1) The same dry season is assumed as Hao et. al. but the fraction of biomass burnt in each of the five months is modified so that the fractions are now 5%, 25%, 40%, 25% and 5% for the appropriate five months of the dry season.

A sharper peak has been observed in the seasonality of the fire season (Cooke et al. 1996) so this would appear to be The forest fires in extra-tropical regions has been assumed to occur in the summer-time. 2) For Africa, satellite observations over a five year period have been used to estimate the seasonality of vegetation fires. Where fires have been detected the seasonality of Hao et al. (1991) has been replaced by the seasonality as estimated by the satellite data.
