Data of river ice timing and thickness for selected river gauges in Russian pan-Arctic over 1970-2012

The dataset includes observational data for river ice thickness (usually each 10 days measurements), dates of beginning and end of ice conditions, dates of beginning and end of freeze-up, and first date of ice drift in spring. The dataset were compiled from official ROSHYDROMET data for 31 hydrological gauges located on medium size rivers with drainage areas from 1190 km2 to 83500 km2 in Russian pan-Arctic. The data were used to better understand interactions between changes in air temperature, river ice thickness and winter streamflow.
