Abstract

Results from local measurements of aerosol and black carbon concentrations in marine expeditions are burdened by technogenic impacts onboard research vessel and failures of instruments due to unfavorable operation conditions. In this report, we present an algorithm of automatic data filtering, ensuring the preparation of observation time series for a subsequent physical analysis. In addition, we discuss an artifact of recording negative black carbon concentrations, caused by insufficient aethalometer sensitivity in the region of the lowest concentrations. It is noted that, to overcome this problem, data should be averaged over a longer period of time, without disregarding negative concentrations.
