Quantifying aggregation bias in marsh carbon flux estimates caused by rhizosphere oxygen heterogeneity

Oxygen (O 2 ) in marsh rhizospheres varies strongly at millimetre scales due to radial oxygen loss (ROL), re-oxidation of reduced compounds, hydrology, and sediment structure. Yet many models estimate heterotrophic (microbial) respiration at a single mean O 2 , which can bias CO...

T-REX: the tile-based representation of lateral exchange processes in ICON-Land

The vast majority of land-surface models uses a tiling-approach to capture the effects of subgrid-scale spatial heterogeneity in the land-surface properties. In most cases, however, the tiles, which represent patches with homogeneous characteristics at and below the surface, are...
