[{"name":"oden-ao-2018-cloud-water-1","title":"Cloud water samples obtained in summertime during the Arctic Ocean 2018 expedition","summary":"This dataset contains results from analyses of chemical composition for elevated clouds in the pristine high Arctic, obtained with a miniaturised cloud water sampler for balloon-borne collection of cloud water.\r\n\r\nSamples were analysed with ion chromatography (IC) and thermal desorption chemical ionization mass spectrometry (TDCIMS) to determine their chemical composition. The samples were further analysed for their ice-nucleating activity (INP).\r\n\r\nThe chemical composition of cloud water can be used to infer the sources of particles upon which cloud droplets and ice crystals have formed. To obtain the samples, we tested and deployed a new sampler on a tethered balloon during the Microbiology-Ocean-Cloud-Coupling in the High Arctic (MOCCHA) campaign in August and September 2018 close to the North pole.","citations":"Zinke J, Salter M, Leck C, Lawler M, Porter G, Adams M, Brooks I, Murray B, Zieger P (2021) The development of a miniaturised balloon-borne cloud water sampler and its first deployment in the high Arctic, Tellus B [Preprint].

Lawler\r\n\r\nWe are grateful to the Swedish Polar Research Secretariat logistical staff and to Oden\u2019s Captain Mattias Peterson and his crew. We thank Leif B\u00e4cklin for his invaluable help in the construction of the instrument. We thank all helpers in the field, particularly Luisa Ickes and Karolina Siegel, for their invaluable assistance and help. Linn Karlsson is thanked for providing the data acquisition software.","category":"Atmosphere","subcategory":"Aerosols","keywords":"Cloud and fog biology and chemistry; Inorganic and organic composition; Ice-nucleating particles; Arctic Ocean; AO2018; Icebreaker Oden","scientist":"Julika Zinke, Emmy Nilsson, Luisa Ickes, Matthew Salter, Caroline Leck, Michael J.
