Fig. 3: Rooting-zone water-storage capacity and apparent rooting depth from the water mass balance.
From: Global patterns of water storage in the rooting zones of vegetation

a,b, Spatial variations of the rooting-zone water-storage capacity, estimated by SCWDX80 (a) and the apparent rooting depth zCWDX80 (b). Values are remapped to 0.1° resolution. Blank grid cells (grey) are either permanent inland water bodies and ocean or locations with long-term accumulation of water deficits. Values are removed in grid cells where more than 99% is non-vegetation surface according to MODIS Landcover42.
