Experimental and Modeling Studies on Reactive Mass Transfer Kinetics of Secondary Organic Aerosol Formation
EMSL Project ID
48010
Abstract
The objectives of this project are to study the reactive mass transfer kinetics of secondary organic aerosol (SOA) formation at low, moderate, and high relative humidities. Through this EMSL-user proposal, we are requesting to deploy EMSL's single-particle mass spectrometer SPLAT II and a differential mobility analyzer (DMA) along with our existing suite of trace gas (PTR-MS, NOx, O3) and aerosol instruments (HR-ToF-AMS, SMPS) in the new 10-m3 flow-through environmental chamber at the Atmospheric Measurement Laboratory (AML) at PNNL. Particle-resolved size, shape, density, morphology, and composition to be measured with SPLAT II will provide us with time evolution information at unprecedented detail. The resulting comprehensive datasets will lead to improved aerosol thermodynamics and reactive gas-particle mass transfer treatments in the regional-scale WRF-MOSAIC aerosol model.
