Exploring Nighttime Tropospheric Chemistry via Hydrocarbon Measurements

这个项目是对农村森林地区异戊二烯（2-甲基-1,3-丁二烯）夜间化学的调查。以前的研究已经观察到这种活性生物烃在夜间惊人地快速衰变。最近的观察表明，这种快速衰变是由于夜间OH自由基的浓度出乎意料地高引起的。本研究将使用塔式和机载测量异戊二烯和几种人为烯烃来检查夜间空气的反应性。这项研究将作为密歇根州佩尔斯顿的氧化剂、光化学、排放和运输研究项目（PROPHET）的一部分进行。

This project is an investigation of the nighttime chemistry of isoprene (2-methyl-1,3-butadiene) in a rural forested area. Previous studies have observed surprisingly rapid nighttime decay of this reactive biogenic hydrocarbon. Recent observations suggest that the rapid decay is caused by unexpectedly large nighttime concentrations of OH radicals. This study will examine the reactivity of nighttime air using tower and airborne measurements of isoprene and several anthropogenic alkenes. This research will be conducted as part of the Program for Research on Oxidants, Photochemistry, Emissions, and Transport (PROPHET) at Pellston, Michigan.
