NAAMEX North American Airborne Mercury Experiment SOAS Co-PI: Jose-Luis Jimenez (CU-Boulder) SOAS Co-PI: Allen Goldstein (UC Berkeley) What are the climate-relevant properties of biogenic aerosol (VOC of biogenic origin)?.How does aqueous chemistry and cloud processing of BVOCs and related aerosols influence atmospheric SOA?.To what extent do anthropogenic influences impact biogenic SOA formation?.What are the chemical and physical processes that control the oxidation of BVOC? How do anthropogenic emissions alter the distribution of the BVOC oxidation products, and what are the implications for the formation of ozone, reactive nitrogen, and aerosol precursors?.What are the magnitudes, variations, and controlling processes for biosphere-atmosphere fluxes of oxidants and reactive carbon and nitrogen across spatial scales relevant to air quality and climate?.SOAS plans to address the following science questions: The SOAS objectives include the direct quantification of VOC, ozone and NOx surface fluxes and reconcile differences with "blank-down" emission estimates better understanding of HOx/NOx/ozone/organics/aerosol distributions, sources and sinks. NOMADSS Principal Investigator: Dan Jaffe, UW The merger of the SOAS, NAAMEX, and TROPHONO field campaigns on the C-130 platform provides the opportunity to address the objectives and science questions for the three respective projects summarized below. The Nitrogen, Oxidants, Mercury and Aerosol Distributions, Sources and Sinks (NOMADSS) project integrates three proposed studies: the Southern Oxidant and Aerosol Study (SOAS), the North American Airborne Mercury Experiment (NAAMEX), and the TROPospheric HONO (TROPHONO). NOMADSS Nitrogen, Oxidants, Mercury and Aerosol Distributions, Sources and Sinks Centreville and Alabama Aquatic Biosdiversity Centre (AABC), Alabama Look Rock, Tennessee and Research Triangle Park (RTP), North Carolina) are involved in the SAS. The individual project descriptions and objectives are described below.ĬOMPLETE LIST OF SAS INVESTIGATORS FUNDED BY NATIONAL SCIENCE FOUNDATION All airborne platforms ( i.e., NSF/NCAR C-130, NOAA WP-3D, Purdue Duchess, and Stonybrook Long-EZ) and ground based facilities (i.e. The field phase for the SAS will be 1 June 2013 through 15 July 2013 and is generally focused in the southeastern United States. SAS's main purpose is to ensure that the objectives of the individual projects are coordinated. The SAS is the "umbrella" for the NOMADSS, SOAS, NAAMEX, TROPHONO, and SENEX projects. The Southeast Atmosphere Study (SAS) is a collaboration that brings together resources and facilities from NSF, NOAA, EPA, and EPRI.
