Continuous Measurements of University of Michigan Biological Camp

9505386卡罗尔这个项目的目标是获得臭氧和臭氧前体的季节性数据，以确定(1)这些物种的气候学，以及(2)负责中西部农村地区臭氧形成和损失的光化学和运输过程。位于密歇根半岛北端附近的密歇根大学生物站将连续测量四个季节密集期的臭氧、一氧化碳、温度、相对湿度、风速、风向和紫外线辐射，以及一氧化氮、二氧化氮和总活性氮。选择的地点经历了大陆性极地和温带大陆性和海洋性气团。将采用以下技术：臭氧的紫外光吸收，一氧化碳的非色散红外分析，二氧化氮的光解和总反应氮的催化转化为一氧化氮，以及通过化学发光检测一氧化氮。将使用光化学盒模型来量化现场臭氧的形成，模拟研究将调查目前对区域运输事件的光化学的理解。

9505386 Carroll The goal of this project is to obtain seasonal data on ozone and ozone precursors in order to determine (1) the climatology of these species, and (2) the photochemical and transport processes responsible for the formation and loss of ozone at a rural site in the midwest. Continuous measurements of ozone, carbon monoxide, temperature, relative humidity, wind speed, wind direction, and ultraviolet radiation, as well as measurements of nitric oxide, nitrogen dioxide, and total reactive nitrogen during four seasonal intensive periods will be conducted at the University of Michigan Biological station, located near the northern tip of Michigan's lower peninsula. The site chosen experiences continental polar and temperate continental and maritime air masses. The following techniques will be employed: ultraviolet absorption for ozone, non-dispersive infrared analysis for carbon monoxide, photolysis of nitrogen dioxide and catalytic conversion of total reactive nitrogen to nitric oxide, and detection of NO via chemiluminescence. A photochemical box model will be used to quantify in situ ozone formation at the site, and modeling studies will investigate the current understanding of photochemistry of regional transport events.
