[{"name":"oden-artofmelt-2023-weather-station-raw-1","title":"Wind, temperature, relative humidity, surface temperature and radiation from expedition ARTofMELT, Arctic Ocean, 2023 \u2014 raw data","summary":"A weather station was deployed on the 7th top deck of the Swedish icebreaker Oden during the ARTofMELT (Atmospheric Rivers and the Onset of Arctic Melt) expedition in the Fram Strait pack ice during the spring transition, 8 May to 14 June of 2023.\r\n\r\nThe primary observed data include wind speed and direction, temperature, surface temperature and downwelling long- and shortwave radiation. Measurements ran continuously during the whole expedition.\r\n\r\nThis dataset is the raw data from the weather station alone. A corresponding complete, quality controlled and user friendly dataset with corrected and averaged data is available separately. In the complete dataset, additional data are added from other measuring systems.","citations":"Murto S, Tjernstr\u00f6m T, Karalis M, Prytherch J (2024) Wind, temperature, relative humidity, surface temperature and radiation from expedition ARTofMELT, Arctic Ocean, 2023.

For example:\r\n* At the beginning of the expedition, the portside surface temperature sensor developed noise due to water creeping into the electronics. This was repaired 22\u2060\u200a\u2013\u200a\u206024 May.\r\n* Towards the end of the expedition a fan malfunctioned on the Rotronic TRH sensor on the foredeck mast. The weather station is equipped with the same sensor, and this was moved to the foredeck mast on 8 June, hence the primary temperature and relative humidity measurement on the weather station is lacking from thereon.\r\nFor more details, see the readme for the processed dataset, by [Murto et al. (2024)](https:\/\/bolin.su.se\/data\/oden-artofmelt-2023-weather-station-1).\r\n\r\n##### Associated processed data\r\nA completed concatenated and quality controlled data set mostly based on these data was created by [Murto et al. (2024)](https:\/\/bolin.su.se\/data\/oden-artofmelt-2023-weather-station-1) and is available separately. This data set also includes additional measurements and calculations as well as quality control flags. The processing from the raw data is complex involving different types of code and calculations, also including ingesting measurements from other instruments. The codes for this is therefore not available. Contact the data creators for more information.\r\n\r\n##### Data creators' roles\r\nThe instrument system was continuously logging and was monitored by the Meteorology team onboard Oden:\r\n- Sonja Murto (operator and dataset creator)\r\n- Ian Brooks (WP lead)\r\n- Michail Karalis (operator)\r\n- Michael Tjernstr\u00f6m (chief scientist; 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":"Weather observations; Wind; Wind speed; Wind direction; Temperature; Relative humidity; Surface temperature; Shortwave radiation; Longwave radiation; Arctic; Arctic Ocean; Meteorology; Atmosphere; ARTofMELT; ARTofMELT 2023 expedition; Icebreaker Oden","scientist":"Sonja Murto, Michael Tjernstr\u00f6m, Michail Karalis, John Prytherch","firstname":"Sonja","lastname":"Murto","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.
