The DublinWind
data frame is basically the time series of daily
average wind speeds from 1961 to 1978, measured in Dublin, Ireland.
These are 6574 observations (18 full years among which four leap years).

This data frame contains the following columns:
numeric vector of average daily wind speed in knots
an integer vector giving the day number of the year, i.e., 1:366.
The periodic pattern along the 18 years measured and the autocorrelation are to be taken into account for analysis, see the references. This is Example 3 of the COBS paper.
