Air quality in Svalbard: sulphur dioxide, nitrogen oxides and ozone in Longyearbyen

The pilot air quality study took place in Longyearbyen from 26.06.2018 to 15.08.2018. The chemiluminescence NO/NO2/NOx Analyzer (model T200), UV Fluorescence SO2 analyser (model T100) and photometric O3 analyser (T400) were placed in the office at the third floor at the University Centre in Svalbard (UNIS), where the inlet of the sampling hose was fixed outside from the window. The SO2 and NOx monitors have been calibrated in-situ with use of zero-air generator and standard SO2 and NO gases with concentration of 361 ppb and 777ppb, respectively. The O3 monitor was weekly calibrated online by the technical personnel from the Norwegian Institute for Air Research. Similar measurements have been performed in Ny-Ålesund and Barentsburg. The data from these settlements is not included in the current archive. However, the measurement results are discussed in the PhD thesis of Alena Dekhtyareva «On local and long-range transported air pollution in Svalbard» (ISBN: 978-82-8236-356-3).

本次试点空气质量研究于2018年6月26日至8月15日在朗伊尔宾进行。化学发光式NO/NO2/NOx分析仪（型号T200）、紫外荧光式SO2分析仪（型号T100）以及光度计式O3分析仪（T400）被安置于斯瓦尔巴大学中心（UNIS）三楼的办公室内，采样软管的进气口固定于窗外。SO2和NOx监测器在现场使用零空气发生器和浓度为361 ppb的标准SO2气体以及浓度为777 ppb的标准NO气体进行校准。O3监测器的校准则由挪威空气研究所的技术人员每周在线进行。在挪威奥勒松和巴伦支堡也进行了类似的测量。然而，这些定居点的数据并未包含在当前档案中。不过，这些测量结果已在Alena Dekhtyareva的博士论文《关于斯瓦尔巴局部及远程输送空气污染》中进行了讨论（ISBN：978-82-8236-356-3）。
