Column 6 is the three-digit data-source flag to identify the wind speed data processing and 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 data-source flag consist of a three-digit sequence in the form "xyz" that describe the origin and transformations of the data values.
