Abstract:
A variety of observational datasets have been combined with modeling to examine the chemical nature and spatiotemporal profile of aerosol in the southwestern United States and Iran in the form of three case studies: (i) a wildfire event along the western United States coast; and examination of smoke and dust impacts on (ii) Arizona and (iii) Iran. For the first study, numerous airborne instrument datasets along the trajectory of a wildfire plume in the western United States reveal concentration enhancements for a wide suite of species including soil tracer species. Airborne cloud water and aerosol data are presented for that study. For the Arizona case study, the intra- and inter-annual frequency and source of extreme aerosol events are discussed. A key objective is separating the frequency of smoke events from regional and Asian dust. For the third study, impacts of dust and smoke on Tehran’s air quality are discussed.
