Conceptual Design for a Gulf Coast Oxidant Transport and Transformation Experiment: Workshop Proceedings and Recommendations

摘要

Thirty atmospheric scientists from government, industry, academia, and the private research sector participated in a workshop in November 1983, in Durham, NC to develop a conceptual design for a study of ozone transport and transformation in the western Gulf coast area. The purpose of the study would be to better understand the unique meteorology and chemistry of the region, and to effectively adapt the EPA Regional Oxidant Model to that geographic area. Working groups focused on the problems of meteorology and atmospheric chemistry and measurement needs and methods. A conceptual design was developed for a five-year program that would include preparatory studies, the 3-month primary experimental program, and data analysis. The preparatory studies would consist of the collection and analysis of all existing data, simulation modeling, smog chamber studies, instrument development, and preliminary, limited field measurements. The primary experiment would consist of an enhanced monitoring network operated continuously, and frequent, intensive short-term experiments; the geographical domain of the study would be about 300 km east-west and 800 km north-south. The routine monitoring would include boundary layer profiles of aerometric parameters by light aircraft and enhanced radiosonde coverage. The intensive studies would rely heavily on sophisticated aircraft platforms such as doppler radar, UV and IR lidar, backscatter lidar, and in-situ gas concentration and flux measurements; gaseous and fluorescent particulate tracers would also be used.
