Description
The South Pole Observatory was established at the geographical south pole at 2837 m above sea level in 1957 as part of the International Geophysical Year. The South Pole Observatory (SPO) is one of six atmospheric baseline observatories for NOAA's Earth System Research Laboratory, Global Monitoring Division (GMD). The National Science Foundation provides the infrastructure for the NOAA/ESRL scientific operations including a state of the art science building named the Atmospheric Research Observatory opened in 1997. ARO was built to house current atmospheric research and replaced NOAA's Clean Air Facility in operation from 1977 to 1997. Two GMD observatory staff spend one year tours of duty at the station which includes a 9 month period of isolation and six months of darkness. Atmospheric data has been collected from South Pole since the International Geophysical Year (IGY), 1957 - 1958.
