Measurements ran continuously during the whole expedition.\r\n\r\nAn associated dataset, containing a concatenation of the original raw files, is available separately. The current dataset is the raw data.","citations":"Tjernstr\u00f6m T, Murto S, Karalis M, Prytherch P (2024) Integrated column water vapor and liquid water paths from expedition ARTofMELT, Arctic Ocean, 2023.

The water vapor measurements are insensitive to the presence clouds, however, the liquid water path measurement is sensitive to water droplets or snow on the surface of the instrument. A fan blows heated air across its surface to remove droplets or snow; a rain sensor indicates if rain was present.\r\n\r\n##### Associated processed data\r\nA concatenated dataset with both these variables was created by [Tjernstr\u00f6m et al. (2024)](https:\/\/bolin.su.se\/data\/oden-artofmelt-2023-microwave-column-water-1) and is available separately. The current dataset is the raw data. No processing code is available.\r\n\r\n##### Data creators' roles\r\nThe instrument system was continuously logging and was monitored by the Stockholm University Meteorology team onboard Oden:\r\n- Michael Tjernstr\u00f6m (chief scientist; operator and dataset creator)\r\n- Sonja Murto (operator)\r\n- Michail Karalis (operator)\r\n\r\nJohn Prytherch (also Stockholm University) is responsible for the instrument system.\r\n\r\n##### The expedition\r\nData were collected during the ARTofMELT 2023 expedition on board the Swedish icebreaker Oden, which was organized by the [Swedish Polar Research Secretariat](https:\/\/www.polar.se\/en\/expeditions\/previous-expeditions\/arctic\/artofmelt-2023\/) from 8 May through 14 June, 2023.","category":"Atmosphere","subcategory":"Weather observations","keywords":"Clouds; Water vapor; Precipitable water; Cloud liquid water; Arctic; Arctic Ocean; Meteorology; Atmosphere; Weather observations; ARTofMELT; ARTofMELT 2023 expedition; Icebreaker Oden","scientist":"Michael Tjernstr\u00f6m, Sonja Murto, Michail Karalis, John Prytherch","firstname":"Michael","lastname":"Tjernstr\u00f6m","address":"Department of Meteorology; Stockholm University","postalcode":"SE-106 91","city":"Stockholm","province":"","country":"Sweden","parameters":"Earth science > Atmosphere","location":"Ocean > Arctic Ocean","progress":"","language":"English","project":"ARTofMELT expedition in spring 2023.
