This dataset consists of seasonally resolved timeseries of surface pressure at 18 Antarctic research stations, spanning 1905-2013. Routine meteorological observations began at most of these stations only around 1960, leaving a very short instrumental record on which to assess Antarctic climate variability and change. Surface pressure is one of the most important variables for assessing changes in climate; for example, a drop in surface pressure since ~1980 around Antarctica likely reflects the influence of the ozone hole. The pre-1960 data were reconstructed based on statistical relationships between the original Antarctic station records and much-longer, mid-latitude station records. A variety of tests were performed to assess the robustness of these relationships and to characterize uncertainty in the reconstructions.
