Technical Note: Simple formulations and solutions of the dual-phase diffusive transport for biogeochemical modeling

Representation of gaseous diffusion in variably saturated near-surface soils is becoming more common in land biogeochemical models, yet the formulations and numerical solution algorithms applied vary widely. We present three different but equivalent formulations of the dual-phase (gaseous and aqueou...
