INTERACT arctic research stations: Historic weather data fetched and plotted from Copernicus Climate Data Store

Plots with historic weather data for arctic research stations covered by International Network for Terrestrial Research and Monitoring in the Arctic (INTERACT). Comparison with WMO climate normal periods 1961-1990 and 1991-2020, averages and stations deviations from the normal periods are calculated and plotted.
The data source for historic data of temperature and precipitation is:
