The Automatic Weather Station (AWS) Project, funded by the NSF Office of Polar Programs, involves collecting meteorological data from an array of automatic weather stations in Antarctica, Greenland, and Peru. Data collection in Antarctica began in 1980. Data are available in tabular ASCII format via the University of Wisconsin's AWS Project Web site at http://uwamrc.ssec.wisc.edu/aws/. Both raw and 'corrected' versions of the data are available via ftp. Information about data processing and station characteristics is also provided.
