    • Hourly air temperature in degrees Fahrenheit and three-digit data-source flag associated with the data, January 1, 1948 - September 30, 2015

    Metadata Updated: September 24, 2025

    The text file "Air temperature.txt" contains hourly data and associated data-source flag from January 1, 1948, to September 30, 2015. The primary source of the data is the Argonne National Laboratory, Illinois. The first four columns give year, month, day and hour of the observation. Column 5 is the data in degrees Fahrenheit. Column 6 is the three-digit data-source flag. They indicate if the air temperature data are original or missing, the method that was used to fill the missing periods, and any other transformations of the data. These flags consist of a three-digit sequence in the form "xyz". The user of the data should consult Over and others (2010) for the detailed documentation of this hourly data-source flag series.
