This project supports the measurement of nonmethane hydrocarbons (NMHCs), selected halocarbons, and a number of light alkyl nitrate in whole air samples collected aboard the NCAR C-130 aircraft during the Tropospheric Ozone Production about the Spring Equinox (TOPSE) experiment. TOPSE will investigate the widely observed springtime maximum of tropospheric ozone in the Northern Hemisphere Subarctic and Arctic. NMHCs are involved in the photochemical production of tropospheric ozone and can directly influence hydroxyl radical concentrations. Changes in composition of NMHCs also will be used to diagnose oxidation mechanisms and rates over the winter/spring transition.

该项目支持测量非甲烷碳氢化合物（NMHCs），选定的卤烃，以及在NCAR C-130飞机上收集的整个空气样本中的一些轻烷基硝酸盐在对流层臭氧生产春分（TOPSE）实验。TOPSE将调查广泛观测到的北方半球亚北极和北极对流层臭氧春季最大值。NMHCs参与对流层臭氧的光化学生成，并可直接影响羟基自由基浓度。NMHCs组成的变化也将用于诊断冬/春过渡期的氧化机制和速率。
