Aerosol Measurements During the Central Chilean Orographic Precipitation Experiment

Abstract

The Central Chilean Orographic Precipitation Experiment was a three-month field campaign (June, July and August 2015) that investigated winter rain events. Reported here are analyses of aerosol measurements made at a coastal site (Arauco, Chile) with a condensation particle counter (CPC) and an aerosol spectrometer (UHSAS). Arauco CPC concentrations are compared to those measured at the NOAA station at coastal Trinidad Head, California (THD). The marine-sector averaged CPC concentration at Arauco is 3014 cm-3 ± 2100 cm-3; at THD the average is 1171 cm-3 ± 772 cm-3. Surprisingly, the Arauco concentrations are larger (p < 0.01). UHSAS measurements were analyzed to determine processes that shaped the ASD at Arauco. Variables analyzed included the fraction of particles smaller than 0.055 mm and moments of the UHSAS-derived aerosol size distributions. There is evidence for both primary particle sources and for new particle formation adding to aerosol burden in oceanic air as it approaches the coast and advects onshore.
