A regional fossil fuel and biofuel emission inventory for particulates has been developed for Africa at a resolution of 0.25° x 0.25° for the year 2005. The original database of Junker and Liousse (2008) was used after modification for updated regional fuel consumption and emission factors. Consumption data were corrected after direct inquiries conducted in Africa, including a new emitter category (i.e. two-wheel vehicles including “zemidjans”) and a new activity sector (i.e. power plants) since both were not considered in the previous emission inventory. Emission factors were measured during the 2005 AMMA campaign (Assamoi and Liousse, 2010) and combustion chamber experiments. Two prospective inventories for 2030 are derived based on this new regional inventory and two energy consumption forecasts by the Prospective Outlook on Long-term Energy Systems (POLES) model (Criqui, 2001). The first is a reference scenario, where no emission controls beyond those achieved in 2003 are taken into account, and the second is for a "clean" scenario where possible and planned policies for emission control are assumed to be effective.
BC and OCp emission budgets for these new inventories will be discussed and compared to the previous global dataset. These new inventories along with the most recent open biomass burning inventory (Liousse et al., 2010) have been tested in the ORISAM-TM5 global chemistry-climate model with a focus over Africa at a 1° x 1° resolution. Global simulations for BC and primary OC for the years 2005 and 2030 are carried out and the modelled particulate concentrations for 2005 are compared to available measurements in Africa.
Finally, BC and OC radiative properties (aerosol optical depths and single scattering albedo) are calculated and the direct radiative forcing is estimated using an off line model (Wang and Penner, 2009). Results of sensitivity tests driven with different emission scenarios will be presented.
