Amundsen-Scott South Pole Station, 1957-2011 quality-controlled surface observational data.

Amundsen-Scott South Pole Station was established by the United States Navy in the austral summer of 1956–1957. This dataset contains the complete record of meteorological observations from the Amundsen–Scott South Pole Station, February 1957 through February 2011 as reported in the local climate data (LCD) files. In cooperation with the South Pole Meteorological Office, this dataset has undergone a full quality control review in preparation for the 50-year climatology report found here:
