Bera M., Over T. M.,2016, Hourly wind speed in miles per hour and three digit flag code associated with the data, January 1, 1948 - September 30, 2014

The text file "Wind speed.txt" contains hourly data and associated flag codes from January 1, 1948, to September 30, 2014. 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 miles per hour and column 6 is the flag (three digit code). The codes have been created to identify the wind speed data processing. They indicate if the data are original or missing, the method that was used to fill the missing periods, and any other transformations of the data. The codes consist of a three-digit sequence in the form "xyz" that describe the origin and transformations of the data values. The user of the data should consult Over and others (2010) for the detailed documentation of the data codes.
