residence time in the Arctic region?
This paper aims at characterising the impact of the atmospheric variability on the aerosol burden and residence time in the Arctic region. For this purpose, a global simulation using an emissions inventory from the year 2000 is performed for the period 2000 2005. The model thus describes a 6-yr evol...
