- Statement
- The key underlying method is the Lomb-Scargle (LS) a well established and efficient methodology to analyse time series data. The LS can be used for the detection of regular cycles, even when hidden in a noisy background and when the time series in question contains data gaps. The LS estimates a power spectrum that indicates the average variance in a time series at different time scales or frequencies. Standard linear de-trending of the data before application of the LS allows an analysis of a 'stationary' time series as the mean and variance should ideally be more-or-less constant. We used two approaches to evaluate the amplitude values. The first involved comparing the full extent of the amplitude data grids with the independent International Geosphere-Biosphere Programme (IGBP) land cover map. This was done with histograms showing the distribution of the amplitude values found within each of the IGBP cover classes. The second approach compared published in situ site observations that describe canopy leaf life cycles through leaf flushing and falling, LAI and litter fall or other observations, with the corresponding amplitude values of these sites.
