Seasonal Cycles of Atmospheric Ion and Aerosol Concentrations in an Urban Area

Abstract

Here the results of monitoring campaign on cluster ions and aerosol concentrations are presented. This measurement procedure was carried out in an urban center, Shkodra City. During this campaign there are measured continuously the concentrations of both ions and aerosols. The measured ions belong to cluster ion category, while measured aerosol particles belong to fine and coarse modes. After monitoring process, measurement data undergo a statistical analyze to obtain the seasonal cycles of these concentrations. These variations let us to estimate the contribution of varying factors on their concentrations, as well as their reciprocal interactions. Seasonal variations of ion concentrations show maximums during warm seasons and minimums during cold seasons. In the case of aerosol concentrations, their seasonal variations strongly depend on the aerosol modes.
