Trends in annual above ground vegetation productivity 2000-2016, version 1, Mar. 2019

The raster file is the temporal trend in above ground vegetation biomass productivity. The vegetation productivity dataset is based on the time series of the Plant Phenology Index (PPI) derived from the MODIS BRDF-Adjusted Reflectance product (MODIS MCD43 NBAR). The PPI index is optimized for efficient monitoring of vegetation phenology and is derived from the source MODIS data using radiative transfer solutions applied to the reflectance in visible-red and near infrared spectral domains. The productivity indicator is based on calculating the area under the PPI temporal curve above the baseline (large integral - LINT) using the TIMESAT software. Relative change of vegetation productivity was then calculated as (YfitLINT2016 – YfitLINT2000)/YfitLINT2000 and expressed in percent scale [%]. Negative values refer to decrease in vegetation productivity, whereas positive values refer to increase in vegetation productivity.
