It happened in August 2010 when it hit -94.7C (-135.8F). Then on 31 July of 2013, it came close again: -92.9C (-135.3F). The old record had been -89.2C set in 1989 at the Russian Vostok Research Station in East Antarctica.
Scientists made the discovery while analysing the most detailed global surface temperature maps to date, developed with data from remote sensing satellites including the new Landsat 8, a joint project of NASA and the US Geological Survey (USGS).
Researchers analysed 32 years' worth of data from several satellite instruments. They found temperatures plummeted to record lows dozens of times in clusters of pockets near a high ridge between Dome Argus and Dome Fuji, two summits on the ice sheet known as the East Antarctic Plateau.
