Create an image with a map or graph of a subset of the data. mapDigital dataset For the scattering coefficient the truncation error correction is performed according to Muller et al. (2009) and assuming a scattering angstrom exponent of 1.15 (Schmeisser et al., 2018). For absorption coefficient, we calculated aerosol absorption coefficient at seven wavelengths according to the formula reported by Drinovec et al. (2015). Corrected aerosol absorption coefficient was derived from the increment of aerosol attenuation measured over a time interval of 60 minutes (dATN). The attenuation was normalized by the sampling flow (F), corrected for the leakage factor z (1%), and the filter collection spot area (S=0.785 cm2). To take into account the loading effect, which would lead to an underestimation of aerosol absorption when filter loading increases, the normalized attenuation increment was divided by the factor (1-kATN), where k is derived from the simultaneous attenuation measurements on two different filter spots characterized by different sampling flows (Drinovec et al., 2015). The parameter k in formula (1) is the average value during the 1-hour time interval and it was calculated assuming that it varied linearly in time. The parameter C compensates for the enhancement of aerosol optical absorption due to the scattering of light by the filter fibers and it was equal to 1.39. Black carbon (BC) concentration derived from the aerosol absorption coefficient at 880 nm and assuming a Mass Absorption Cross section of 7.77 m2/g (according to the instrument manufacturer).. Both absorption and scattering coefficient measurements are normalized at standard pressure and temperature conditions (1 atm and 0 degC), averaged over a 1-hour period, and provided at all available wavelengths.
