25-years Svalbard data record reveals change in long-range transport of sulphur agents to the warming Arctic
Dekhtyareva, Alena (Conference object, 2019)Current study investigates the 25-years seasonal trend in the concentration of SO2and non-sea salt SO42-and compares observed changes with the evolution in emission of sulphur agents in primary source regions of anthropogenic aerosols and alteration in characteristics of air masses transporting pollutants to Svalbard. -
Effect of seasonal mesoscale and microscale meteorological conditions in Ny-Ålesund on results of monitoring of long-range transported pollution
Dekhtyareva, Alena; Holmén, Kim; Maturilli, Marion; Hermansen, Ove; Graversen, Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-06)Ny-Ålesund is an international research settlement where the thermodynamics and chemical composition of the air are monitored. The present work investigates the effects of micrometeorological conditions, mesoscale dynamics and local air pollution on the data collected at two different locations around the village. Daily filter measurements of sulphur dioxide and non-sea salt sulphate from the temporary ... -
Influence of local and regional air pollution on atmospheric measurements in Ny-Ålesund
Dekhtyareva, Alena; Edvardsen, Kåre; Holmén, Kim; Hermansen, Ove; Hansson, Hans-Christen (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)The Zeppelin observatory is a research station near the village Ny-Ålesund in Svalbard. The facility delivers data to international projects devoted to high data quality monitoring of the background air pollution in the Arctic. An approach for quantifying the influence of local and regional pollution on measurements that may be misinterpreted as long-range transported one, is presented here. The ... -
Influence of seasonal mesoscale and microscale meteorological conditions in Svalbard on results of monitoring of long-range transported pollution [poster]
Dekhtyareva, Alena; Holmén, Kim; Maturilli, Marion; Hermansen, Ove; Graversen, Rune (Conference object; Konferansebidrag, 2018)The Zeppelin Observatory is an atmospheric monitoring station located on the northwest coast of Spitzbergen island, in the Svalbard archipelago. The station provides background air composition, meteorological and climatological data for numerous research projects. The observatory is located on a mountain ridge in a region with complex topography that affects local atmospheric circulation ... -
