Extended Data Table 1 Results from multiple sensitivity tests of our gridded weighted hydroclimate reconstruction

From: Northern Hemisphere hydroclimate variability over the past twelve centuries

  1. a, Statistics from correlating the full gridded weighted reconstruction at the grid-cell level with reconstructions derived from using different subsets of proxy data including tests removing one proxy type at the time. b, Statistics from correlating the full gridded weighted reconstruction at the grid-cell level with PDSI drought atlas reconstructions. c, Results from correlating the decadal-resolved reconstruction from the proxy subset including only records with at least decadal resolution and centennial or better dating control with the decadal mean gridded 5° × 5° GHCN5 instrumental annual precipitation data over the twentieth century.
