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.

项目名称：利用涡旋相关技术开发船载大气-海洋臭氧通量测量系统建议建造和部署一台灵敏、快速响应的臭氧分析仪，以量化大气-海洋臭氧通量。这项实验将补充已有的船舶平台ECM技术。除了这项新技术的测试外，同时进行的化学、物理和生物海水测量将提供一个机会来调查海洋臭氧通量的变化和生物相关性。这项研究将为未来研究臭氧向海洋和淡水湖沉积的规模和控制提供新的数据，并将为阐明二次挥发性有机化合物的形成提供新的数据，这些二次挥发性有机化合物是大气氧化剂(如臭氧)与覆盖海洋表面的有机微层反应而释放的。臭氧沉积数据将纳入地面-大气气体交换模式以及大气化学和输送模式，以便更好地描述和预报全球大气组成和气候。这项研究涉及在表层海洋低层大气研究中确定的几个研究需要。
