Example for
harmonic analysis
 

WindDataSuite implements a module for performing Fourier analysis. The Fourier analysis comprises harmonic analysis for discrete temporal periods as yearly and daily waves, as well as spectral analysis for the complete frequency domain of the time series.

In the following example, the mean, amplitude, and phase of the 24-hour waves (Fig.2) have been calculated with harmonic analysis from the measured 10-minutes wind speeds in all heights (Fig.1).

Data range:
1 year (365 days), sampling rate 10 minutes
Processed channels:
31 height levels of wind speed
Computing time:
approx. 1 second
Processing time:
approx. 1 minute
