Opis:: This paper presents the results of a comparison of basic meteorological parameters in two Arctic fjords situated on the west coast of Spitsbergen, the main island of the Svalbard archipelago. Air temperature, wind speed and direction, humidity and cloud cover from the period 2005 to 2016 are described and compared with previous (from 1975) analyses of meteorological conditions in the investigated region. Such a choice of dates coincides with the time the GAME project measurements were carried out. The main goal of this study was to compare meteorological conditions in two fjords: Hornsund and Kongsfjorden, during the time of rapid climate changes. The results are collated with research results available in literature from previous years. We discovered that in the investigated period the climate of the Hornsund region is more oceanic than in Kongsfjorden. The stable level of the difference in climate elements is manifested and is evident mainly through greater amplitudes in air temperatures in Kongsfjorden, and in stronger winds in Hornsund.

Opis:: We present results of measurements of aerosol physical properties conducted on board of r/v Oceania during two cruises to the Spitsbergen region in 2014 (AREX 2014) and 2015 (AREX 2015). Measurements of aerosol size distribution, aerosol scattering coefficient and black carbon concentrations were made in two different Spitsbergen fjords: Hornsund and Kongsfjorden. The aerosol size distribution was measured in the size range from 0.09 μm to 47 μm using two aerosol size distribution spectrometers and a standard condensation particle counter. For the scattering coefficient an integrating nephelometer was used. Black carbon concentration was measured by an aethalometer. Temporal variabilities in physical properties of aerosol observed during the AREX 2014 and AREX 2015 campaigns were much higher than the differences between both fjords. The basic factors influencing aerosol conditions were advection and local generation of marine aerosol. In 2015 an episode of smoke advection was observed in both fjords causing an increase in the mean black carbon concentration from 7–12 ng m−3 to about 60 ng m−3, and an aerosol scattering coefficient at 550 nm from 2–4 Mm−1 to 12–17 Mm−1. Moreover, under certain conditions statistically significant gradients in aerosol optical properties were observed along the fjord axis reflecting an impact of mountains surrounding the fjords.
