The SCAR READER Project: toward a high-quality database of mean Antarctic meteorological observations

A new dataset of monthly and annual mean near-surface climate data ( temperature, surface and mean sea level pressure, and wind speed) for the Antarctic region has been created using historical observations [ Scientific Committee on Antarctic Research ( SCAR) Reference Antarctic Data for Environmental Research ( READER)]. Where possible, 6-hourly surface synoptic and automatic weather station observations were used to compute the means. The ability to quality control the data at the level of individual observations has produced a more accurate series of monthly means than was available previously. At the time of writing, the mean data are available on the Internet (http://www.antarctica.ac.uk/met/programs-hosted.html). Data for 43 surface-staffed stations and 61 automatic weather stations are included in the database. Here, mean temperature, pressure, and wind speed data for 19 occupied stations with long records are provided.
