This proposal aims to better understand how tropical intraseasonal variability (periods of 40 to 60 days) influences the chemical components of the global atmosphere. The results of the research aim to improve regional air-quality forecasts on weekly and monthly timescales. The highly vertically resolved ozone concentrations from the surface up to 20 kilometres, measured by balloon-borne instruments called ozonesondes, will be used as a dynamical tracer. The knowledge gained from the ozonesonde data will be used to elucidate the chemical origins of the tropical variability related to biomass burning activities and convective lightning, as well as the subtropical variability related to the polar vortex dynamics.

该提案旨在更好地了解热带季节内变化（周期为40至60天）如何影响全球大气的化学成分。研究结果旨在改善每周和每月的区域空气质量预报。由称为臭氧探测仪的球载仪器测量的、高度垂直分辨的、距离地面20公里的臭氧浓度将被用作动态示踪剂。从臭氧探测仪数据中获得的知识将用于阐明与生物质燃烧活动和对流闪电有关的热带变异性的化学来源，以及与极涡动力学有关的亚热带变异性。
