Abstract [en]

In the spring that followed the winter 2015-16, a coordinated snow survey across Svalbard was organized under the multinational (Community Coordinated Snow Study in Svalbard) C2S3 project. The goals of the survey were to investigate the spatial variability of the seasonal snow cover, including physical, chemical and biological properties, over a wide array of sites at three different altitude levels (Fig. 1) and using standardized protocols. A particular focus of the project was directed at black carbon (BC) deposition in snow, in order to better constrain estimates of its impact on snow albedo.In order to interpret results of this survey, knowledge of the climatology and air transport patterns to the different sampling sites is needed. Such knowledge is essential to determine how239typical or atypical the 2015-16 winter was with respect to snow conditions, and to identify the most probable source regions for aerosols deposited in snow during this period. Accordingly, an analysis was performed of surface climatological conditions and synoptic air flow patterns during the period of interest using atmospheric reanalysis products, satellite imagery, and air back- trajectory modeling. This presentation will report on the results, with special emphasis on those findings most relevant to BC transport and deposition in Svalbard snow.
