 The spatiotemporal characteristics of temperature extremes over Antarctica are largely unknown, but using quality-controlled daily datasets from Antarctic weather stations, it is shown that annual maximum and minimum temperatures exhibit a decreasing pattern over Antarctica from the coast to inland regions. This feature holds for the warmest daily maximum and coldest daily minimum temperatures, which define the intensity of extremes, but not for the number of warm, cold, days measuring the frequency of extremes, which show limited dependence on latitude or elevation. During 1970 to 2000, temperature extremes in the South Orkney Islands and on the margins of East Antarctica show opposite trends, especially with a significant increasing and decreasing trend in warm events, respectively. During 1999 to 2013, the intensity and frequency of extreme temperatures decrease significantly over West Antarctica, but the trends vary greatly across sub-regions of Antarctica. These results help to decipher the climate regimes of Antarctica, fill current gaps in the map of global climate extremes, guide the future design of Antarctic observational networks, assess the capability of re-analysis datasets and climate models.
