Paper Abstract

An automated two-channel 4-wave aethalometer providing monitoring measurements of the mass concentration of black carbon with the preset time periodicity and duration of air sampling has been developed. Air with aerosol containing black carbon is sampled to FH-111 diffuse filter tape. The MDA-03 aethalometer has been intercalibrated with the 5012 MAAP photometer (Thermoscientific Co., USA) in simultaneous measurements of the Black Carbon concentration in the surface air layer at the Aerosol Station of IAO SB RAS. A technique has been developed for correction of measured values of the BC concentration for the variable transparency of the diffuse filter. This technique allows us to take into account the effect of spot loading and to reconstruct true values of the concentration. The technique has been tested successfully in smokes from high-temperature open flame burning of pine wood biomass (high bulk of BC absorbing particles) and low-temperature smoldering of the same material (high bulk of Brown Carbon scattering particles) in the Large Aerosol Chamber of IAO SB RAS.
