EPCAPE-PT-LANL Measurements: Proton Transfer Reaction Mass Spectrometer
Abstract
Coastal cities offer a unique environment for studying aerosol-cloud interactions and the effects of urban emissions on cloud properties. As part of the Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE), the Partitioning Thrust by Los Alamos National Laboratory (EPCAPE-PT-LANL) was conducted. Our campaign focused on measuring the optical and chemical properties of aerosols and their interactions within marine stratocumulus clouds in La Jolla, California. EPCAPE-PT-LANL enhances the primary goals of EPCAPE through innovative observations of vapor-phase transitions between aerosols and cloud droplets, the impact of black carbon on aerosol-cloud dynamics, and the effects of cloud processing on aerosol optical properties. Instrument: IONICON High-Resolution PTR-TOF-MS - Trace VOC Analyzer. Concentrations were calculated based on theoretical reaction rates of each species with H3O+. Details of the calculation are found in the PTR-MS Ionicon Manual. Data Notes: It is a high-resolution PTR-TOF-MS we have sub-selected relevant species.
