STAR Upper Air Soundings

This dataset contains upper air meteorological rawinsonde soundings from the operational Environment Canada observing stations in the STAR domain. The data contains the Iqaluit, Pangnirtung, and other stations in the STAR domain with soundings taken twice per day at (00 and 12 UTC). Meteorological parameters measured include: pressure, height, speed, direction, temperature, dew point temperature, and other parameters. Iqaluit was the only location on southern Baffin Island where regular 12-hourly upper-air observations were made. During storms and other significant weather events, the standard upper-air releases were supplemented with additional radiosondes at 3- or 6-hourly intervals. From the period of 10 October–30 November 2007, there were 51 special radiosonde releases. A portable radiosonde unit was deployed in

the community of Pangnirtung to conduct simultaneous releases with those in Iqaluit during selected severe weather events. A total of 18 radiosondes were released in Pangnirtung between the dates of 2 and 18 November 2007.
