1992 Workshop on Detection of Tropospheric OH

OH自由基是对流层光化学的核心，对其浓度的测量为我们的化学知识提供了一个极其敏感的测试。然而，由于其浓度极低且可能存在干扰物质，因此其检测面临相当大的挑战。目前，有几种很有希望的候选方法，有些已经准备好进行现场试验，有些尚未开发。SRI国际将于1992年初组织和主办一个讲习班，以评价目前的能力，讨论并因此改进实验方法，并考虑相互比较测试。HO2的检测并不像HO检测那么困难，但也具有挑战性，并且还将讨论使用类似或不同的方法进行测量。讲习班的参加者将包括大气建模者、参与实地测量和相关技术发展的研究人员以及化学物理学的实验人员。将撰写一份报告，描述研讨会的讨论、结论和建议。

The OH radical is central to the photochemistry of the troposphere, and measures of its concentration furnish an extremely sensitive test of our knowledge of the chemistry. Its detection, however, poses a considerable challenge due to its very low concentration and possible interfering species. At this time, there are several promising candidate methods, some ready for field trials and others not yet developed. SRI International will organize and host a workshop in early 1992 to assess current capabilities, discuss and thereby improve the experimental approaches, and consider intercomparison test. HO2 detection is not so difficult as HO detection but is also challenging, and discussion of its measurement using similar or variant methods will also be included. The workshop participants will include atmospheric modelers, researchers involved in field measurement and the associated technique development, and experimentalists in chemical physics. A report will be written describing the workshop discussions, conclusions, and recommendations.
