Modelling concentrations and trends of atmospheric pollutants in the arctic over a 37years period

We have simulated air pollution levels over the Arctic for a 37 years period from 1979 to 2015 using a 3D hemispheric chemistry-transport model, the Danish Eulerian Hemispheric Model (DEHM). The observed and simulated trends have been analysed at a number of sites in the Arctic. The levels of SO 2 a...

Description
Summary:We have simulated air pollution levels over the Arctic for a 37 years period from 1979 to 2015 using a 3D hemispheric chemistry-transport model, the Danish Eulerian Hemispheric Model (DEHM). The observed and simulated trends have been analysed at a number of sites in the Arctic. The levels of SO 2 are decreasing over the simulated period, which follows the decreased anthropogenic emission in source areas. Differences in trends between sites can be explained by the influence from different source areas. The levels of O 3 are almost constant over the 37 year period and no difference in trends between sites can be seen.
