Holistic Interactions of Shallow Clouds, Aerosols, and Land-Ecosystems (HI-SCALE): Nanoparticle Composition and Precursors

21 August 2016 - 27 September 2016

Lead Scientist: James Smith

Observatory: SGP

A small suite of instruments will be placed in the Guest Instrument Facility (GIF) in support of HI-SCALE during IOP2. The objectives of our measurements are to fully characterize the formation and evolution of atmospheric aerosol particles through measurements of gas-phase precursor and ambient nanoparticle composition. Specifically, we plan to: (1) investigate the role of acid-base chemistry in new particle growth through measurements of ammonia and amines as well as organic and inorganic acids in both atmospheric nanoparticles and the gas phase; (2) investigate the contribution of other surface-area or volume-controlled processes to nanoparticle formation and growth, such as the uptake of Extremely Low Volatility Organic Compounds (ELVOCs); (3) evaluate the performance of a new instrument being developed with funding from the DOE SBIR program for measuring gas-phase amines; (4) together with our colleagues measuring on the ground and onboard the ARM G-1 aircraft during HI-SCALE, create a comprehensive data set related to new particle formation and growth that can be used in modeling efforts by our group and DOE Aerosol Life Cycle collaborators.
