Bolivia campaign – particle nucleation and urban influence at 5240 masl

Bolivia campaign

Aerosol particle nucleation and urban influences are studied at the Chacaltaya GAW Station (CHC) in the Bolivian Andes (16°21.014'S, 68º07.886'W, 5240 masl). The Chacaltaya mountain directly faces a plateau of 3800 masl in the south and west and is separated from the Amazon basin by higher peaks in the north and east.

Research groups from La Paz, Stockholm, Helsinki, Innsbruck, Granada, Leipzig, and Karlsruhe combine their instruments to characterize the aerosol from November 2017 to June 2018. Focus of our contribution is the molecular composition of gas- and particle phase on the mountain and in the La Paz – El Alto metropolitan area.
