[{"title":"Present weather sensor visibility and precipitation data from the Arctic Ocean 2016 expedition","summary":"Measurements of visibility, precipitation type and intensity, and the corresponding 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 2016 (AO2016) expedition to the central Arctic Ocean in August and September 2016.","citations":"","comments":"Visibility, up to a maximum range of 50 km, air temperature and precipitation type and intensity determined by the Vaisala FD12p present weather sensor installed above Oden\u2019s bridge on the 7th deck, at a height of 27 m above sea level. The system, owned by the Finnish Meteorological Institute (FMI), was deployed as part of the Stockholm University weather station. The system additionally reports instantaneous, 15-minute and 60-minute WMO present weather codes.\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.\r\n\r\n\r\nCoordinates (lat, lon) for the observations are not included in this dataset, but they are the same as in the Weather data from MISU weather station during the Arctic Ocean 2016 expedition.\r\n\r\n\r\nMore information about the Canadian-Swedish Arctic Ocean 2016 expedition is available from the Swedish Polar Research Secretariat.","category":"Atmosphere","subcategory":"Weather observations","keywords":"Visibility; Precipitation type; Precipitation intensity; Meteorology; Arctic boundary layer; Arctic clouds; High Arctic; Arctic Ocean 2016; AO2016; AO16; ACAS; Oden","scientist":"John Prytherch, Michael Tjernstr\u00f6m","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 2016 expedition.
