From: Interrelations of vegetation growth and water scarcity in Iran revealed by satellite time series

Iran-wide aggregated statistics of vegetation and hydrometeorology. (a): Annual Z-scores. Reference period to generate Z-scores applies for all parameters to the common data availability (i.e. period of GRACE TWS) (b): Pearson’s R values with indication of significance of the correlation (solid boundary: p <0.05, dashed boundary: p <0.1, no boundary: p>=0.1).
