TOPSE

The TOPSE investigation combined model studies and simulations with a set of chemical and photochemical measurements taken over the critical winter-spring transition in the northern mid-to-high latitude troposphere. The overall goal of the experiment was to investigate the chemical and dynamic evolution of tropospheric chemical composition over mid- to high-latitude continental North America during the winter/spring transition; a particular emphasis was placed on the springtime ozone maximum in the troposphere. As the experiment progressed additional effort was used to investigate dramatic ozone depletion events found over large regions of the Arctic surface layer.
