  <Quality>NCDC, AFCCC, and FNMOD (2000) states that 'data have undergone extensive automated quality control, and additional manual quality control for U.S. Air Force stations, U.S. Navy stations, and U.S. National Weather Service stations.' Upon extracting and reformatting the data, Julienne Stroeve (NSIDC) checked that all data values were correctly filled in.</Quality>

  <Summary>This product consists of meteorological data from 105 Arctic weather stations and 137 Antarctic stations, extracted from the National Climatic Data Center (NCDC)'s Integrated Surface Hourly (ISH) database. Variables include wind direction, wind speed, visibility, air temperature, dew point temperature, and sea level pressure. Temporal coverage varies by station, with the earliest record in 1913 and the latest in 2002. Data are in tab-delimited ASCII text format, with one file per station and year. Graphs of meteorological variables throughout the time series accompany the ASCII data. Data are available via FTP.</Summary>
