CHEMICAL COMPOSITION AND DYNAMICS OF THE UPPER TROPOSPHERE AND THE LOWER STRATOSPHERE: OVERVIEW OF THE PROJECT

摘要

The DRAGON-3 cooperation study on the upper troposphere and the lower stratosphere (UTLS) is based on new satellite data and modern atmospheric models. The objectives of the project are: (i) assessment of sat-ellite data on chemical composition in UTLS, (ii) dy-namical and chemical structures of the UTLS and its variability, (iii) multi-scale variability of stratospheric ozone, (iv) climatology of the stratospheric aerosol layer and its variability, and (v) updated ozone climatology and its relation to tropopause/multiple tropopauses. In this paper, we present the main results of the project.
