Project Title: Development of Ship-Borne Atmosphere-Ocean Ozone Flux Measurements by the Eddy Correlation TechniqueThe PIs propose to build and deploy a sensitive, fast response ozone analyzer to quantify air-sea ozone fluxes. This experiment will complement established technologies for ECM from a ship platform. In addition to the testing of this new technique, concurrent chemical, physical, and biological ocean water measurements will offer an opportunity to investigate the variations and biological dependencies of ocean ozone fluxes. This research will result in a future program for the study of the magnitude and controls of ozone deposition to oceans and freshwater lakes and will also provide new data for elucidating the formation of secondary volatile organic compounds that are released as a result of reactions between atmospheric oxidants, such as ozone, with the organic microlayer covering the ocean surface. Ozone deposition data will be incorporated in surface-atmosphere gas exchanges models and atmospheric chemistry and transport models for better descriptions and forecasts of global atmospheric composition and climate. This research addresses several research needs identified in the surface ocean lower atmosphere study.

项目标题：通过涡流相关技术的船舶大气 - 海洋臭氧通量测量，PIS提议构建和部署敏感，快速响应的臭氧分析仪，以量化空气臭氧通量。该实验将补充来自船舶平台的ECM的既定技术。除了测试这项新技术外，同时的化学，物理和生物海水测量还将提供一个机会来研究海洋臭氧通量的变化和生物学依赖性。这项研究将导致未来的计划，以研究对海洋和淡水湖泊的臭氧沉积的大小和控制，还将提供新的数据，以阐明由于大气氧化剂之间反应而释放的二次挥发性有机化合物的形成。 ，例如臭氧，有机微层覆盖了海面。臭氧沉积数据将纳入表面 - 大气交换模型，大气化学和传输模型，以更好地描述全球大气组成和气候。这项研究解决了地表海洋大气层研究中发现的几项研究需求。
