项目摘要

In situ aircraft measurements of O_3, CO, total reactive nitrogen (NO_y), NO, and non-methane hydrocarbons (NMHCs) were made over the western Pacific Ocean and Australia during the Biomass Burning and Lightning Experiment (BIBLE)-A and B conducted in August-October 1998 and 1999. The mixing ratios of these species reached minimum values over the tropical Pacific Ocean throughout the troposphere due to active convection, although occasional enhancements in reactive nitrogen occurred caused by NO production by lightning near New Guinea. The low values of O_3, CO, NO_y, and NO in the tropical upper troposphere are compared with a 3-dimensional chemistry and transport model, which reproduces the latitudinal variations of O_3, NO_y, and NO from northern midlatitudes to the equator reasonably well. Over Australia, the levels of O_3, CO, NO_y, NO, and NMHCs were elevated throughout the troposphere over those observed in the tropical Pacific both in 1998 and 1999. Biomass burning over Australia strongly enhanced the mixing ratios of these species only within the boundary layer due to subsidence. Free tropospheric air masses originated from Indonesia, the Indian Ocean, Africa, and southern midlatitudes were identified basing on 14-day back trajectories. The levels of O_3, CO, NO_y, and NMHCs in these air masses were much higher than those from the tropical Pacific due to their stronger sources from biomass burning and lightning. The median values of these species in different types of air masses were similar except for the southern midlatitude air, which showed somewhat higher values. Biomass burning and lightning are found to be important for O_3 and its precursors in these air masses.
在1998年8 - 10月和1999年8 - 10月进行的生物质燃烧和闪电实验(BIBLE)-A和B期间,在西太平洋和澳大利亚上空进行了O_3、CO、总活性氮(NO_y)、NO和非甲烷碳氢化合物(NMHCs)的现场飞机测量。这些物种的混合比达到最低值,在整个对流层的热带太平洋,由于活跃的对流,虽然偶尔增强活性氮发生在新几内亚附近的闪电NO生产所造成的。用一个三维化学和输送模式比较了热带对流层上部O_3、CO、NO_y和NO的低值,该模式较好地再现了从北方中纬度到赤道的O_3、NO_y和NO的纬向变化。1998年和1999年,澳大利亚对流层O_3、CO、NO_y、NO和NMHCs浓度均高于热带太平洋。在澳大利亚的生物质燃烧强烈增强了这些物种的混合比,只有在边界层内,由于沉降。根据14天的返回轨迹,确定了来自印度尼西亚、印度洋、非洲和南部中纬度地区的自由对流层气团。这些气团中的O_3、CO、NO_y和NMHCs浓度远高于热带太平洋地区,这是由于它们的生物质燃烧和闪电来源较强。这些物种在不同类型的空气质量的中位数值是相似的,除了南部中纬度空气,这显示出较高的值。生物质燃烧和闪电是这些气团中O_3及其前体物的重要来源。
