abstract = {Biotic leaf transpiration (T) and abiotic evaporation (E)
are the two major pathways by which water is transferred
from land surfaces to the atmosphere. Earth system models
simulating the terrestrial water, carbon and energy cycle
are required to reliably embed the role of soil and
vegetation processes in order to realistically reproduce
both fluxes including their relative contributions to total
evapotranspiration (ET). Earth system models are also being
used with increasing spatial resolutions to better simulate
the effects of surface heterogeneity on the regional water
and energy cycle and to realistically include effects of
subsurface lateral flow paths, which are expected to feed
back on the exchange fluxes and their partitioning in the
model.Using the hydrological component of the Terrestrial
Systems Modeling Platform (TerrSysMP), we examine the
uncertainty in the estimates of T/ET ratio due to horizontal
model grid resolution for a dry and wet year in the Inde
catchment (western Germany). The aggregation of topography
results in smoothing of slope magnitudes and the filtering
of small-scale convergence and divergence zones, which
directly impacts the surface-subsurface flow. Coarsening of
the grid resolution from 120 m to 960 m increased the
available soil moisture for ground evaporation, and
decreased T/ET ratio by about $5\%$ and $8\%$ for dry and
wet year respectively. The change in T/ET ratio was more
pronounced for agricultural crops compared to forested
areas, indicating a strong local control of vegetation on
the ground evaporation, affecting the domain average
statistics.},
