[{"name":"oden-ao-2018-present-weather-1","title":"Present weather sensor visibility and precipitation data from the Arctic Ocean 2018 expedition","summary":"Measurements of visibility, precipitation type and intensity, and the corresponding the World Meteorological Organization (WMO) weather codes.\r\n \r\nThe dataset provides rare high quality meteorological observations from sea-ice regions of the Arctic Ocean. They enable analysis of meteorological conditions and provide context for other measurements and analysis associated with the expedition.\r\n \r\nThe measurements are from the present weather sensor operating on Icebreaker Oden\u2019s 7th deck at 25 m above sea level during the Arctic Ocean 2018 (AO2018, also referred to as MOCCHA-ACAS-ICE) expedition to the central Arctic Ocean in August and September 2018.","citations":"","comments":"Visibility, up to a maximum range of 20km, air temperature and precipitation type and intensity determined by the Vaisala PWD22 present weather sensor installed above Oden\u2019s bridge on the 7th deck, at a height of 27m above sea level. The system was operated as part of the Stockholm University ACAS project. The system additionally reports instantaneous, 15-minute and 60-minute WMO present weather codes.\r\n\r\n\r\nUntil 2018-08-13 20:10, the sensor was set to only report visibility. After this date, the full set of measurements were reported.\r\n\r\n\r\nData from the system are combined into a cruise-length file. The data are time-averaged to both 1-minute and 30-minute intervals, to correspond with the micrometeorological averaging periods used for the mast sensors.","category":"Atmosphere","subcategory":"Weather observations","keywords":"Visibility; Precipitation type; Precipitation intensity; Arctic Ocean 2018; AO2018; AO18; Meteorology; Arctic boundary layer; Arctic clouds; High Arctic; ACAS","scientist":"John Prytherch","firstname":"John","lastname":"Prytherch","address":"Department of Meteorology (MISU); Stockholm University","postalcode":"SE-106 91","city":"Stockholm","province":"","country":"Sweden","parameters":"Earth science > Atmosphere","location":"Ocean > Arctic Ocean","progress":"Completed","language":"English","project":"Arctic Ocean 2018.
