<P> The lowest natural temperature ever directly recorded at ground level on Earth is − 89.2 ° C (− 128.6 ° F; 184.0 K) at the Soviet Vostok Station in Antarctica on July 21, 1983 by ground measurements . </P> <P> A 2009 study estimated that under exceptional climate conditions similar to those recorded at Vostok 1983, temperatures higher on the plateau around Dome Argus could drop lower than − 95 ° C (− 139 ° F; 178 K). On August 10, 2010, satellite observations measured a surface temperature of − 93.2 ° C (− 135.8 ° F; 180.0 K) at 81.8 ° S 59.3 ° E, along a ridge between Dome Argus and Dome Fuji, at 3,900 m elevation . The result was reported at the 46th annual meeting of the American Geophysical Union in San Francisco, in December 2013; it is a provisional figure, and may be subject to revision . </P>
