在本文中，我们分析了在美国宇航局的全球对流层实验（GTE）太平洋探索任务在热带太平洋（PEM-Tropics） B阶段运动中拍摄的对流层臭氧和水蒸气剖面中看到的不同层。总之，在这个运动中观测到的层数比在PEM-Tropics A运动中观测到的层数少。然而，在发现的这些层中，臭氧丰富的水蒸汽较少的层相对较多（68%对52%）。赤道—热带B期间各层占据的对流层取样百分比不到赤道—热带A期间的一半（8%对20%）。这两种活动之间的差异表明了分层发生的季节性变化。南半球附加臭氧探测仪（shadowz）网络的测量证实了这一点。
In this paper we analyze distinct layers seen in the tropospheric ozone and water vapor profiles taken during NASA's Global Tropospheric Experiment (GTE) Pacific Exploratory Mission in the Tropical Pacific (PEM-Tropics) Phase B campaign. In summary, fewer layers were observed in this campaign than during the PEM-Tropics A campaign. However, of those layers found, there were relatively more ozone-rich-water-vapor-poor layers (68% versus 52%). The percentage of the sampled troposphere occupied by layers during PEM-Tropics B was less than half of that found during PEM-Tropics A (8% versus 20%). The differences between these two campaigns suggest a seasonal variation in the occurrence of layers. This is confirmed using measurements made by the Southern Hemisphere Additional Ozonesondes (SHADOZ) network.
