Linking drought indices to atmospheric circulation in Svalbard, in the Atlantic sector of the High Arctic.

Based on long-term climatological data from Ny-Ålesund, Svalbard Airport-Longyearbyen and the Polish Polar Station at Hornsund, we undertook an analysis of drought indices on Spitsbergen Island, Svalbard, for the period 1979-2019. The features and causes of spatiotemporal variability of atmospheric drought in Svalbard were identified, as expressed by the standardized precipitation evapotranspiration index (SPEI). There were several-year periods with SPEI indicating the dominance of drought or wet conditions.

Hansbreen Snowpit Dataset - over 30-year of detailed snow research on an Arctic glacier.

Snow cover is a key element in the water cycle, global heat balance and in the condition of glaciers. Characterised by high temporal and spatial variability, it is subject to short- and long-term changes in climatic conditions. This paper presents a unique dataset of snow measurements on Hansbreen, an Arctic glacier in Svalbard.

Types of pollen season depending on the weather conditions in Wrocław (Poland), 2002-2011.

The aim of the study was to characterise pollen season types according to weather conditions in Wrocław (south-western Poland) in the years 2002-2011. Over the period analysed, the start date of the pollen season (determined by the 95 % method) ranged from 10 July 2002 to 28 July 2010. The start date of the pollen season can be determined by using Crop Heat Units (CHUs).
