The Integrated Global Radiosonde Archive (IGRA) consists of radiosonde and pilot balloon observations at over 1500 globally distributed stations. Observations are available for standard, surface, tropopause and significant levels. The period of record varies from station to station, with many extending from 1970 to present. Station records are updated daily and are available online at no charge.

The time period of archived data varies for each station. Most locations have soundings from 1973 - present. Radiosondes are released twice a day (0Z and 12Z) at each site and data is in ASCII format. From the link, go to 'North Pole' under Region and then type the station identifier/number in the box located at the bottom left of the page.
