PARASOL / GRASP as reference Beiging Oklahoma Banizoumbou Mongu 4 selected regions (1200 km x 1200 km) + Africa 1 year (2008) of POLDER-3 data processing with GRASP Banizoumbou: Surface: Grassland. Aerosol: Coarse mode is dominated (dust). Mongu: Surface: Savanna. Aerosol: Fine mode is dominated (biomass burning). Beijing: Surface: Urban. Aerosol: Fine and Coarse modes (industrial/dust). Cart_Site (Oklahoma): Surface: Grassland. Aerosol: Fine and Coarse modes (rural).
