As expected aerosol mass concentration was dominated by desert dust in coarse mode. (en.ilmatieteenlaitos.fi)
The detailed chemical composition of exhaust particles was determined by using a soot particle aerosol mass spectrometer (SP - AMS). (en.ilmatieteenlaitos.fi)
Mike Alexander, Alex Laskin, Yuri Desyaterik, and John Ortega, who work at DOE's Environmental Molecular Sciences Laboratory (EMSL) at PNNL and Xiao - ying Yu of PNNL's Atmospheric Science and Global Change Division, collected an extensive set of measurements of aerosol mass, size distribution, composition, and particle morphology using an array of in - situ techniques and aerosol sampling approaches.
