Modeling Anthropogenic Sulfur Transport to the Arctic

Abstract

A numerical model aimed at simulating Arctic air quality must be able to reproduce the following three main characteristics: the seasonal cycle, the episodic character of the Arctic pollution events and the vertical distribution of the pollutant in polar regions. Chemical transport models used in the past are capable of simulating pollution transport quite well, but they either depend on meteorological preprocessing or climatological data to provide the parameters for the physical processes in the atmosphere. Some models include the effects of clouds as stochastic processes in space-time.
