Trajectory-based analysis on the source areas and transportation pathways of atmospheric particulate matter over Eastern Finland
In this study, we utilize aerosol mass spectrometer (AMS) and multi-angle absorption photometer (MAAP) measurements to assess the most predominant source regions of various atmospheric aerosol constituents transported to Eastern Finland. The non-refractory composition data from the AMS were measured...
