An overview of transport and its relation to tropospheric chemistry

Abstract:

Large-scale transport and mixing has a large and non-linear impact on tropospheric chemistry. It regulates tropospheric chemical budgets by linking tropospheric chemical sources to regions of chemical destruction. It also governs pollution extremes by providing the conditions under which local pollutants can build up locally or by which pollutants are transported over large distances. The latter may occur between continents, between mid-latitudes and high-latitudes or between the stratosphere and the troposphere. In this talk I will review interactions between tropospheric chemistry and transport and highlight gaps in our current knowledge.
