Description:

Long-term measurements of the light absorption coef ﬁcient ( babs) obtained with a particle soot absorption photometer (PSAP), babs(PSAP), have been previously reported for Barrow, Alaska, and Ny-Ålesund, Spitsbergen, in the Arctic. However, the effects on babsof other aerosol chemical species coexisting with black carbon (BC) have not been critically evaluated. Furthermore, different mass absorption cross section (MAC) values have been used to convert babsto BC mass concentration ( MBC=babs/MAC). We used a continuous soot monitoring system (COSMOS), which uses a heated inlet to remove volatile aerosol compounds, to measure babs(babs(COSMOS)) at these sites during 2012 –2015.
