Distribution of surface soil locations in North and Central America used to derive the relationship between ACL and VPD. (a) Sample locations plotted against 30 year mean vapor pressures for July (data is a spatial interpolation of gridded WorldClim 2 data46, and the map was produced using ArcMap69. (b–d) Distribution of VPD, MAT and ACL values at our sites.
