[1]大气中的CO2混合比测量使用连续测量系统板载湾流-II飞机之间的北方中纬度和南亚热带地区的生物质燃烧和闪电实验阶段A（圣经A）的活动在1998年9月至10月。热带地区上空CO2的垂直分布从地面到13公里高度几乎是恒定的。在热带边界层观测到生物质燃烧和海洋释放造成的CO2增加。对流层上层的观测结果表明，在2°N ~ 7°N范围内，半球间交换被有效抑制。对流层上部的空气的半球间输送在该区域被有效地抑制。北方和南半球的CO2混合比率几乎是恒定的，平均值分别约为百万分之365和366。7°N以北和2°N以南观测到的CO2和NOy混合比的相关性明显不同。这一事实有力地支持了在《圣经》A期间对流层上部的南北边界位于2°N-7°N附近的结果，因为该边界不一定是永久性的特征。
[1] The atmospheric CO2 mixing ratio was measured using a continuous measurement system onboard a Gulfstream-II aircraft between the northern midlatitudes and the southern subtropics during the Biomass Burning and Lightning Experiment Phase A (BIBLE A) campaign in September–October 1998. The vertical distribution of CO2 over tropical regions was almost constant from the surface to an altitude of 13 km. CO2 enhancements from biomass burning and oceanic release were observed in the tropical boundary layer. Measurements in the upper troposphere indicate interhemispheric exchange was effectively suppressed between 2°N–7°N. Interhemispheric transport of air in the upper troposphere was suppressed effectively in this region. The CO2 mixing ratios in the Northern and Southern Hemispheres were almost constant, with an average value of about 365 parts per million (ppm) and 366 ppm, respectively. The correlation between the CO2 and NOy mixing ratios observed north of 7°N was apparently different from that obtained south of 2°N. This fact strongly supports the result that the north-south boundary in the upper troposphere during BIBLE A was located around 2°N–7°N as the boundary is not necessary a permanent feature.
