Spatial-Temporal Variability of the δ18O Values and the Snow Cover Structure on the Territory of the Meteorological Observatory of the Moscow State University

The isotope composition (δ18O values) of different-age snow layers, which make up the snow cover at the time of maximal water storage, was compared with the isotope composition of precipitation that formed these layers during the winter season of 2018/2019 on the territory of the meteorological observatory, Moscow State University. It was found that the expected isotopic composition becoming heavier from the time of precipitation to the time of sampling was practically independent of the age of the layers.
