AEROSOLIFE

Aerosol Life Cycle IOP at BNL

1 June 2011 - 31 August 2011

Lead Scientist: Arthur Sedlacek

Observatory: OSC

Intensive aerosol observations were conducted in a region exposed to anthropogenic, biogenic, and marine emissions with atmospheric processing times depending on air mass trajectories and time of day. There were three main foci of the planned IOP that took advantage of the unique capabilities provided by new instrumentation in the MAOS: 1. Aerosol light absorption: How does the aerosol mass absorption coefficient (absorption per unit mass of BC) vary with atmospheric processing? Do observations agree with a shell-core model? 2. Secondary organic aerosol (SOA): How does the amount and formation rate of SOA vary with atmospheric processing and sources? Can heretofore unavailable measurements of oxygenated VOCs (from high resolution PTR-MS) explain the “excess” SOA observed in other locations? 3. Aerosol as CCN: What is the effect of different organic components on CCN formation?
