Abstract
Changes in the total moisture content of the troposphere in the Arctic zone are examined using the TIXI permanent GPS observation site (Tiksi) as an example. To calculate the moisture content using GPS data, linear and power-law regressions were determined for the ratio of the “mean weighted” average temperature in a conventional vertical column to surface air temperature obtained from radiosonde observations over a 10-year period from 2012 to 2021. The rate of change in atmospheric water vapor content over Tiksi was examined as a function of surface temperature over a fouryear period. Seasonal variations and a decrease in average levels at air temperatures above 24 °C were noted. Long-term changes in total moisture content were obtained using continuous GPS measurements and radiosonde observations at the Tiksi subarctic observation point.
