Microtomographic Measurements of Total Air‐Water Interfacial Areas for Soils

Water Resources Research
Synchrotron X‐ray microtomography (XMT) was used to measure total air‐water interfacial areas (Aaw) as a function of water saturation (Sw) for several soils that comprise a range of physical and geochemical properties.
