Abstract

The vertical profiles of aerosol and BC concentrations measured in flights of the aircraft-laboratory of IAO SB RAS in cloudless troposphere in 2000-2016 near the village of Zav’yalovo (Novosibirsk Oblast) are analyzed. The temporal dynamics of the annual average aerosol concentration is characterized by a weak linear trend from -0.04% a year at a height of 0.5 km to -1.3% at 7 km. In 2010, minimal BC concentrations were observed at all heights. The decrease of the BC concentration in 2000-2010 (-3.6÷-10%) and its increase in 2010-2016 (+4.8÷25%) have led to the situation that the BC trend became positive for the entire period of observations: +2.6÷5.3%. The year-to-year variations of the seasonal average aerosol and BC concentrations before and after 2010 have been estimated. It is shown that the differences in the seasonal average vertical profiles of the aerosol and BC concentration for the intervals of 2000-2008 and 2000-2016 are statistically insignificant.
