The coldest air temperature recorded by thermometer at Dome A since January 2005 thus far (as of September 28, 2010) was in July 2005: . This may have been beaten by an unconfirmed reading of in June 2019. The lowest air temperature () ever measured on the surface of the Earth was recorded by satellite on August 10, 2010 between Dome Argus and Dome Fuji. Analysis of satellite data and atmospheric models shows that Ridge A, which is located southeast from Dome A, is potentially an even better location to look for the lowest temperatures on Earth.
