Five factors solution seems to be best fitting also for data from winter campaign. Constrained profiles were again HOA factor (a-val = 0,3) and BBOA factor (a-val = 0,3). HOA factor was combined mainly with chlorides, sulfate and ammonium whereas BBOA factor is related mostly to potassium and partly also to nitrates. Like in summer LV-OOA factor remained mostly organic and both inorganic factors SO4+NH4 and NO3+NH4 also remained almost unchanged. Both inorganic factor profiles were supplemented by rather low concentrations of partly oxidized organic aerosol.
