Isotope characteristic of snow cover in Tomsk

Abstract

The snow cover has a high sorption ability that way it is a source of information in identifying anthropogenic pollution of the environment, and it also contains a climate signal. Results of studies of the oxygen and hydrogen isotope composition of snowmelt and the carbon isotope composition of black carbon extracted from the dispersed fraction of the atmospheric aerosols deposited on the snow cover during the winter periods of 2016–2018 years are shown in the paper. The relationships between air temperature, the amount of precipitation and the isotope oxygen and hydrogen composition of melting snow are analyzed.
