A consistent High Arctic climatological ...

A consistent long-term (1979-2018) dataset from the Arctic meteorological site the Polish Polar Station Hornsund (77°00'N 15°33'E), located in the SW part of Spitsbergen. The Station is managed by the Institute of Geophysics Polish Academy of Sciences. The data series includes daily, monthly and annual air temperature (TA), PDD, NDD, the sum of precipitation (Precip), air humidity (RH), atmospheric pressure (PA), wind speed (WS) and direction (WD), sunshine duration (SD), cloudiness, and visibility (VV). This rich dataset, now available online, is a valuable source for documenting the state of the climate in SW Spitsbergen that represents the Atlantic sector of the Arctic. Nowhere on the planet is climate warming faster than here. With the positive trend of mean annual temperature +1.14°C/decade, the climate in Hornsund is warming five times faster than the global average.
