Nitrous Acid (HONO) Chemistry in the Non-Urban Atmospheric Boundary Layer

该项目包括一个全面的实地和实验室测量计划，以研究非城市环境边界层中的亚硝酸（HONO）。两个假设将被检验。第一项研究将研究表面上的硝酸光解作用是否可能构成白天HONO的主要来源，并作为非城市环境中氮氧化物的再活化途径。第二部分将评估地面/植被表面对大气中HONO时空分布的潜在影响。现场测量将在密歇根大学生物站进行，该站是“氧化剂：光化学、排放和运输研究计划”（PROPHET）的所在地。

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).
