Concise description:

Anomaly of fAPAR (fraction of Absorbed Photosynthetically Active Radiation): 10-day time composite, 1 Km spatial resolution, derived from the Moderate resolution imaging spectroradiometer (MODIS) global coverage satellite products. MODIS-derived 10-day maps are produced in-house starting from the standard MOD15A2 product. Low quality data are masked according to the quality flag in the MOD15A2 product (Myneni et al. 2000), 8-day values are interpolated at 10-day time step using a weighted average (inverse distance in time) of the two closest images, and a temporal smoothing is performed by means of an exponential filter (a=0.5) of the 10-day data (Brown and Meyer, 1961). The anomalies are calculated using a MODIS-consistent baseline with the data available from January 2001 to December 2014.
