Sodankyla Tahtela
Reference CryoNet Station Information

This station includes measurements at or around the sounding station in Sodankylä, Finland. Main weather parameters at the station were measured manually until 2009. Instrumentation at the station has increased during the years. The meteorological observations for Sodankyla sounding station cover more than 100 years:

- Air temperature measured since 1908
- Snow depth measured since 1911
- Other main weather paremeters (SYNOP observations) are measured since 1959
- First solar radiation observations 1950
- Ozone vertical profiles are measured since 1988
- Satellite reception building and 2,4m satellite receiver 2003
- Automatic Sounding Station 2006
- Automatic Weather Station 2006
- Fourier Transform Spektrometer (FTS) instrument measuring greenhouse gas columns 2009

The name of the station was updated from Sodankyla Sounding Station to Sodankyla Tahtela to match the official WMO station name.
