GEOS-Chem PM2.5 in 2012 with (left) and without (centre) dust and sea salt, and the increase due to future fossil fuels (right)

Data Description:
GEOS-Chem PM2.5 and ozone surface concentrations obtained using 2012 emissions and using a scenario of future (2030) emissions due to fossil fuel use in the electricity generation and transport sectors. The model is simulatted at the native resolution of the NASA GEOS-5 meteorology over Africa (0.5° x 0.667°; latitude x longitude). Both the 2012 and 2030 simulations use 2012 meteorology.
