[1]关于春分的对流层臭氧产生(TOPSE)实验是在2000年2-3月期间进行的，目的是研究北美中高纬度对流层化学的演变。该实验利用航空现场和对微量气体、辐射和气溶胶的遥感测量，结合模型模拟，描述了冬春过渡期间控制臭氧和氧化剂演变的主要过程。本文介绍了TOPSE实验的主要科学问题，描述了任务的进行，并介绍了在这一特别部分的一系列配套论文中讨论的科学结果。该实验的重要发现之一是，从冬季到春季，对流层臭氧的增加主要是由对流层的原位光化学产生决定的，而不是由平流层的输送决定的。在飞行过程中，还获得了对广泛的地表臭氧消耗事件的独特观测，以及痕量气体和气溶胶随纬度和海拔变化的季节性变化。
[1] The Tropospheric Ozone Production about the Spring Equinox (TOPSE) experiment was conducted during February–March, 2000 to study the evolution of tropospheric chemistry at mid to high latitudes over North America. The experiment used airborne in situ and remote sensing measurements of trace gases, radiation, and aerosols, combined with model simulations, to describe the major processes that control evolution of ozone and oxidants during the winter-spring transition. This paper introduces the major scientific questions of the TOPSE experiment, describes the conduct of the mission, and introduces the scientific results discussed in a series of companion papers in this special section. Among the significant findings of the experiment was that tropospheric ozone increases from winter to spring were dominated by in situ photochemical production in the troposphere, rather than by transport from the stratosphere. Also unique observations of widespread surface ozone depletion events, and of seasonal evolution of trace gases and aerosols as a function of latitude and altitude, were obtained over the course of the mission.
