Three data formats are available: Matlab (.mat), NetCDF (.nc) and comma separated value (.csv) text, with an accompanying readme (.rtf) file. 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’s 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. Data 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. Coordinates (lat, lon) for the observations are not included in this dataset, but they are the same as in the <a href="">Weather data from MISU weather station during the Arctic Ocean 2016 expedition</a>. More information about the Canadian-Swedish <a href=""> Arctic Ocean 2016 expedition</a> is available from the Swedish Polar Research Secretariat.
