Leaf phenology synchrony for Meso- and South America
THIS DATASET HAS BEEN SUPERSEDED The latest version is Leaf phenology synchrony for Meso- and South America v2
Data recalculated with amended algorithm, as the original was not allowing for the difference between the average amplitude or equivalently average deviation (i.e. ave amplitude time series sense) and the maximum deviation. Hence we needed to multiply the original dataset by 2.0/SQRT(0.5) to get average peak-to-trough.

* well synchronized, where the leaf bud burst and senescence of the individual plants within the pixel occurs near simultaneously, yielding a high amplitude value. Often this matches with an area of low species diversity (e.g. arable land) or with areas where the growth of all plants is controlled by the same driver (e.g. precipitation).
* poorly synchronized, where the leaf bud burst and senescence of individual plants within a pixel occurs at different times of the year, yielding a low amplitude value. Often this matches with an area of high species diversity and/or where several drivers could be controlling growth.

Provenance & quality
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.
