摘要：

In this article we investigate near-surface air temperature (NSAT) and soil temperature variability at four depths in the region of the White Sea, Murmansk and Arkhangelsk Regions, and Republic of Karelia. For the analysis we used NOAA-CIRES-DOE 20th Century Reanalysis (Version 3) reanalysis data for the 1980-2015 time period and data of bent-stem thermometers at 5, 10, 15, 20 cm depths and extraction thermometers at 20, 60, 80, 120, 240 and 320 cm depths for 1985-2021 time period. Average variability of NSAT is estimated using linear trend as +0.028 degrees C/year. For soil temperature a linear trend is of +0.0137 degrees C/year on surface (0 cm), +0.0136 degrees C/year at 10 cm depth, +0.0142 degrees C/year at 40 cm depth and +0.0133 degrees C/year at 100 cm depth.
