Aerosol measurements in Siberia

The atmospheric aerosols were studied in remote parts of Novosibirsk region (South-Western Siberia) and in Akademgorodok (research town of Russian Academy of Sciences) in the years 1992-1994. The distances between different measuring locations were: 30-500 km. The total aerosol light scattering (into 45 degree ) by aerosol particles was measured by commercially available nephelometer FAN-A. The aerosol light scattering was measured in terms of units, related to the molecular light scattering of clean air. Aerosol mass concentration was measured by weighting of AFA-HA filters where the aerosol particles were sampled 24 hours with volume velocity of about 600 l/min. Number concentration of aerosol particles with r>1 mu m was measured by commercially available optical particle counter PKZV-6.
