This data set consists of continuous meteorological data, monthly climatological summaries, and upper air meteorological data for the NOAA/CMDL Pt. Barrow Observatory. Data include hourly average observations of air temperature, station pressure, and surface wind direction and speed. The data set also includes atmospheric radiation at the Barrow Observatory. Radiation data consist of hourly-averaged data for downwelling short-wave radiation, in watts per square meter. The radiation data were used to determine the snow disappearance date at Barrow on the basis of objective, radiometric measurements made over open tundra (http://www.esrl.noaa.gov/gmd/grad/snomelt.html).
These data are available from the NOAA Earth System Research Laboratory, http://www.esrl.noaa.gov/gmd/dv/data/. Meteorological data are available via FTP at ftp://aftp.cmdl.noaa.gov/data/meteorology/in-situ/brw/, and radiation data are available at ftp://aftp.cmdl.noaa.gov/data/radiation/baseline/brw/.
