Northern Michigan Atmospheric Chemistry Characterized by PATH (Patterns in Atmospheric Transport History): Meteorological Support of PROPHET

该项目将为位于密歇根北部农村的密歇根大学生物站的氧化剂研究计划：光化学、排放和运输(PROPHET)提供气象支持。PROPHET计划是一项涉及臭氧形成的光化学过程的多研究者实地研究。现场将部署一个综合探测系统，包括一个多普勒风廓线仪、一个无线电声学探测系统、一个玻璃探测气球发射设施，以及一个测量气压、温度、湿度、风和辐射的当地气象塔。该设施将提供整个对流层的对流层风、温度和湿度的常规垂直剖面，以便深入了解先知基地的边界层动态。以前的场强已经证明，了解边界层动力学对于解释在现场观测到的化学可变性至关重要。这项研究的结果将提供在Prophet 2000和2001年度密集实地试验期间发生的边界层输送过程的主要制约因素。

This project will provide meteorological support for the Program for Research on Oxidants: Photochemistry, Emissions, and Transport (PROPHET) at the University of Michigan Biological Station in rural Northern Michigan. The PROPHET program is a multi-investigator field study of photochemical processes involved in ozone formation. An integrated sounding system will be deployed at the site, consisting of a Doppler wind profiler, a Radio Acoustic Sounding System, a GLASS rawinsonde balloon launching facility, and a local meteorological tower measuring pressure, temperature, humidity, wind and radiation. This facility will provide routine vertical profiles of tropospheric winds, temperature and moisture throughout the troposphere in order to provide insight into the boundary layer dynamics at the PROPHET site. Previous field intensives have demonstrated that understanding boundary layer dynamics is critical to the interpretation of chemical variability observed at the site. The results of this study will provide key constraints on boundary layer transport processes occurring during the PROPHET 2000 and 2001 intensive field experiments.
