   Atmospheric pressure is typically measured using barometers with errors of < 1 
   mb.

   Air temperature is measured using a variety of instruments. The thermistors 
   typically have measurement errors of < 0.1oC, but where these instruments are 
   installed on the buoys necessitates some care in interpreting the data. Prior 
   to 1991, most measurements were taken from thermistors placed inside the hull 
   of air dropped buoys, and were used primarily to calibrate the barometers. 
   These buoys were sometimes covered with snow during winter, and were often 
   warmed from insulation during summer. In 1992, the IABP began deploying buoys 
   which measured true air temperatures from shielded thermistors at 2 meters 
   height. For a detailed discussion of the temperature measurements from buoys, 
   see Rigor et al. 2000.

   Most buoys are positioned by the Argos systems on NOAA polar orbiting 
   satellites. The Argos system results in positions with a measurement error of 
   < 300 m. Global Position Systems have been installed on many of the newer 
   buoys, and can be positioned with errors of < 100 m.

Group: Summary

   The International Arctic Buoy Programme (IABP) maintains a network of drifting 
   buoys to provide meteorological and oceanographic data for real-time 
   operational requirements and research purposes including support to the World 
   Climate Research Programme (WCRP) and the World Weather Watch (WWW) Programme. 
   An average of 25 buoys are in service at any time. The IABP drifting buoy data 
   products described here are 12-hour interpolated pressure, temperature, 
   position, and ice velocity grids available by year from 1979 through the 
   present.

   Drifting buoys measure atmospheric pressure, air temperature, and other 
   geophysical quantities. These data are processed at the University of 
   Washington's Polar Science Center, and are interpolated to produce gridded 
   fields. Data are usually updated by May of each year, and are available online 
   from the Polar Science Center. NSIDC catalogs the data set and provides this 
   documentation with links to the Polar Science Center's IABP site in order to 
   publicize and facilitate access to the data.

   Several related data sets are available from the Polar Science Center's IABP 
   site, including a CD-ROM containing IABP data and derived products from 1979 
   through 1999, an ocean buoy data set with temperature and salinity from 
   drifting buoys from 1985 through 1994, GIF files graphically depicting gridded 
   products, and a surface air temperature (SAT) data set (the IABP/POLES SAT 
   data set) that combines data from buoys, manned drifting stations, and 
   meteorological land stations.
