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.
Samples 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).
The 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.

Data description
Data are included in three xlsx spreadsheet files separated according to analysis methods. There is also one xlsx file containing the sampling coordinates.
Ice-nucleating activity (INP)
The INP file contains frozen fraction and INP concentration per litre of cloud water at respective temperatures.
Ion chromatography (IC)
The IC file contains concentrations of inorganic ions obtained from ion chromatography.
Thermal desorption chemical ionization mass spectrometry (TDCIMS)
The TDCIMS file contains ion counts for inorganic and organic compounds obtained from thermal desorption mass spectrometry. The good-ion column indicates if the signal is trustworthy and above the blank value.
More details are given in the corresponding peer-reviewed reference.
Comments
Photos and more material on the cloud water sampler can be found at the MOCCHA project website, managed by the Department of Environmental Science, Stockholm University.
