Nitrogen Oxides at the University of California, Blodgett Forest Research Station

加州大学布洛吉特森林研究站正在进行的一氧化氮、二氧化氮、总过硝酸盐、总烷基硝酸盐、硝酸和总奇数氮(NOY)的观测记录将被延长。PI开发了一种基于热解离-激光诱导荧光(TD-LIF)的四通道新型仪器。此外，PI计划测量紫外线辐照度。通过合作，将可以测量臭氧、碳氢化合物、一氧化碳和二氧化碳。将使用盒子和一维建模来理解和解释过去和正在进行的测量。此外，PI打算证明他的仪器进行涡旋协方差通量测量的能力，然后进行完整的年度周期测量。该项目如果成功，将展示痕量气体浓度和通量测量的新技术，并将为部分受人为污染影响的森林地区的光化学提供新的见解。

An ongoing observational record of nitric oxide, nitrogen dioxide, total peroxynitrates, total alkylnitrates, nitric acid, and total odd nitrogen (NOy) at the University of California Blodgett Forest Research Station will be extended. The PI has developed a novel instrument based on thermal dissociation - laser-induced fluorescence (TD-LIF) with four channels. In addition, the PI plans to measure UV irradiance. Through collaborations, measurements of ozone, hydrocarbons, carbon monoxide, and carbon dioxide will be available. Box- and 1-dimensional modeling will be used to understand and interpret past and ongoing measurements. Furthermore, the PI intends to demonstrate the capability of his instrument for carrying out eddy-covariance flux measurements, and then carry out a full annual cycle of measurements. This project, if successful, will demonstrate new technology for trace gas concentration and flux measurements, and will provide new insights into the photochemistry of forested areas that are partially impacted by anthropogenic pollution.
