This project includes a comprehensive field and laboratory measurement program to study nitrous acid (HONO) in the boundary layer of non-urban environments. Two hypotheses will be tested. The first will examine the possibility that nitric acid photolysis on surfaces constitutes a major daytime source of HONO and serves as a remobilization pathway for nitrogen oxides in the non-urban environment. The second will evaluate the potential for the ground/vegetation surfaces to influence both temporal and spatial HONO distributions in the atmosphere. The field measurements will be conducted at the University of Michigan Biological Station, the location of the Program for Research on Oxidants: PHotochemistry, Emissions, and Transport (PROPHET).

该项目包括一个综合的现场和实验室测量计划，用于研究非城市环境边界层中的亚硝酸 (HONO)。 将测试两个假设。 第一个将检查表面上的硝酸光解是否构成日间 HONO 的主要来源，并作为非城市环境中氮氧化物的再动员途径。 第二个将评估地面/植被表面影响大气中 HONO 时间和空间分布的潜力。 现场测量将在密歇​​根大学生物站进行，该站是氧化剂研究计划：光化学、排放和运输（PROPHET）的所在地。
