A flexible device to produce a gas stream with a precisely controlled water vapour mixing ratio and isotope composition based on microdrop dispensing technology
Sodemann, Harald; Dekhtyareva, Alena; Bremer, Alvaro Fernandez; Seidl, Andrew Walter; Maccali, Jenny (Journal article; Peer reviewed, 2023)Here we describe a versatile device to produce a gas stream with a precisely controlled water vapour mixing ratio and stable water isotope composition based on microdrop dispensing technology. To produce a moist ... -
Polycyclic aromatic hydrocarbons (PAHs) and their nitrated and oxygenated derivatives in the Arctic boundary layer: Seasonal trends and local anthropogenic influence
Drotikova, Titiana; Dekhtyareva, Alena; Kallenborn, Roland; Albinet, Alexander (Journal article; Peer reviewed, 2021)A total of 22 polycyclic aromatic hydrocarbons (PAHs), 29 oxy-PAHs, and 35 nitro-PAHs (polycyclic aromatic compounds, PACs) were measured in gaseous and particulate phases in the ambient air of Longyearbyen, the most ... -
Springtime nitrogen oxides and tropospheric ozone in Svalbard: results from the measurement station network
Dekhtyareva, Alena; Hermanson, Mark H.; NIkulina, Anna; Hermansen, Ove; Svendby, Tove Marit; Holmén, Kim; Graversen, Rune Grand (Journal article; Peer reviewed, 2022)Svalbard is a remote and scarcely populated Arctic archipelago and is considered to be mostly influenced by long-range-transported air pollution. However, there are also local emission sources such as coal and diesel power ...
