The NDVI was scaled NDVI to total fPAR (fraction of Photosynthetic Active Radiation \\[i.e., 400nm to 700nm\\] absorbed by plants, which ranges from 0 to 1) using the approach of Donohue et al (2008).  At each grid-cell the time series of total fPAR estimates are then temporally decomposed using the algorithm of Donohue et al (2009). This partitions the per-pixel and per time-step total fPAR estimate into the recurrent and persistent fPAR components.  In general the recurrent component is related to crops / grasses with a strong annual cycle of greenness, and the persistent component is related to evergreen trees and shrubs.  There are however vegetation types which do not accord to this \"one-to-one\" classification, for example evergreen / improved pastures (these are typically regarded as being persistent) and deciduous trees (these are typically regarded as being recurrent). The fPAR values (total, recurrent and persistent) where then converted to percentage green vegetation cover (ranging from 0% to 100%), this was performed assuming a 0.01 fPAR change represented a 1% change in vegetation cover.  The digital numbers (DNs) of the fPAR data range between 0 to 1000, and so green percentage cover was calculated as fPAR value / 10.  As examples, an fPAR DN of 500 = 50% and 350 = 35% etc.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2014) fPar derived from MODIS for the Sydney Basin.
