Collaborative Research: The Multiphase Chemistry of Inorganic Halogens in the Marine Boundary Layer at Hawaii During Summer

涉及无机卤素的化学过程及其对海洋边界层(MBL)氧化过程的影响被认为是重要的，但这种过程的速度是高度不确定的。卤素原子前体被认为起源于涉及海盐气溶胶的反应，气溶胶离子平衡中的卤化物“赤字”证明了这一点。该项目是对海洋空气中卤素化学的合作研究，来自弗吉尼亚大学、夏威夷大学、麻省理工学院、马克斯·普朗克研究所、NCAR和AOML/NOAA的研究人员参与了该项目。实地考察将于1999年9月在夏威夷的瓦胡岛进行。测量将包括HCl*、Cl*、Cl(总)、ClO、BrO、IO、碱性反应性无机溴、臭氧、NMHC‘s、NO、NOx、NOY、CO以及尺寸分离气溶胶的主要离子和溴化学。数据将根据热力学计算和光化学模型进行解释。

Chemical processes involving inorganic halogens and their influences on oxidation processes in the marine boundary layer (MBL) are believed to be important, but the rates of such processes are highly uncertain. Halogen-atom precursors are thought to originate from reactions involving sea-salt aerosol, as evidenced by halide "deficits" in aerosol ionic balances. This project is a collaborative study of halogen chemistry in marine air, involving researchers from the University of Virginia, the University of Hawaii, Massachusetts Institute of Technology, Max Planck Institute, NCAR and AOML/NOAA. The field study will take place during September 1999 in Oahu, Hawaii. Measurements will include HCl*, Cl*, Cl(total), ClO, BrO, IO, alkaline-reactive inorganic Br, O3, NMHC's, NO, NOx, NOy, CO, and major ion and bromine chemistry of size-segregated aerosols. Data will be interpreted based on thermodynamic calculations and photochemical models.
