Annual bias and trend-corrected metrics on intra-annual vegetation dynamics expressed through the NDVI

Details

This dataset provides intra-annual metrics based on a daily time-series of Normalized Difference Vegetation Indices (NDVI). This time-series was corrected to account for the continued deterioration of the AVHRR sensors following the methodology proposed by Hansen et al. (2016).
