Ny-Ålesund is located on a fjord at the west coast of Svalbard (Spitsbergen). In this region, ocean currents from lower latitudes impact the sea water temperature, and the ocean is a heat storage affecting the local climate. Although Ny-Ålesund is situated in the high Arctic (78.9°N, 11.9°E), daily mean temperature in summer is above the freezing point. The interannual temperature variability in winter is large, but temperature rarely drops below -25°C.

Climate Change

Annual mean temperature in Ny-Alesund 1993 to 2014

Since the beginning of our meteorological measurements in 1993, climate in Ny-Ålesund has changed. The annual mean temperature has risen by 1.3° C per decade, while the strongest warming is observed during the winter season.
The 'Arctic Amplification' of global warming is analysed under various aspects by measurements and model simulations.
