Short summary
Aerosol chemistry and the sources and processes driving the observed temporal and diurnal variations of PM were studied in a polluted urban environment during winter 2013. These results were compared to a similar campaign from winter 2010. Meteorology strongly influenced PM composition, both directly and indirectly. Nighttime reactions played a more important role in 2013 and the influence from a nighttime formed residual layer that mixed down in the morning was also much more intense in 2013.
