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).
