Vertical Air Profile in the Canadian Arctic, 2012-2020

This data was collected by Environment and Climate Change's (ECCC) Meteorological Services Canada (MSC), balloons are filled with either Hydrogen or Helium, a Contractor prepares the instruments and release the balloons twice each day, three hundred and sixty-five (365) days per year, to monitor the data and messages produced, and to ensure the prompt transmittal of the data. Stations with data archived in this dataset are: Baker Lake, NU; Cambridge Bay, NU; Inuvik, NWT; Iqaluit, NU; Inukjuak, QC; Resolute Bay, NY; Fort Smith, NWT; Hall Beach, NU; Kuujjaq, QC; Norman Wells, NWT; Whitehorse, YT Eureka, NU; and Alert, NU.

These stations complete soundings of the upper atmosphere twice daily, 01:20 and 13:20 (UTC), for each day of the year. The observations are taken by releasing a gas-filled balloon with an attached instrument which is tracked via one of a variety of electronic navigational methods. This attached instrument transmits meteorological data relating to temperature, humidity, and the height of standard atmospheric pressure levels. In addition, tracking of the balloon allows for computation of winds and wind shear at upper levels of the atmosphere.

Data is collected and processed automatically by sounding equipment and transmitted to the Canadian Meteorological Centre for inclusion in atmospheric models which are used to produce a number of weather forecasts. In addition, the data is shared internationally for use in many global weather monitoring and forecasting programs.

This data was mined daily from an online repository managed by MSC, and was only publicly available to users in 24 hour increments for 24 hours total. PDC undertook archiving these data to provide open access and documentation to users for valuable reuse.
