abstract = {Plant physiological properties have a significant influence
on the partitioning of radiative forcing, the spatial and
temporal variability of soil water and soil temperature
dynamics, and the rate of carbon fixation. Because of the
direct impact on latent heat fluxes, these properties may
also influence weather-generating processes, such as the
evolution of the atmospheric boundary layer (ABL). In this
work, crop-specific physiological characteristics, retrieved
from detailed field measurements, are included in the
biophysical parameterization of the Terrestrial Systems
Modeling Platform (TerrSysMP). The physiological parameters
for two typical European midlatitudinal crops (sugar beet
and winter wheat) are validated using eddy covariance fluxes
over multiple years from three measurement sites located in
the North Rhine–Westphalia region of Germany. Comparison
with observations and a simulation utilizing the generic
crop type shows clear improvements when using the
crop-specific physiological characteristics of the plant. In
particular, the increase of latent heat fluxes in
conjunction with decreased sensible heat fluxes as simulated
by the two crops leads to an improved quantification of the
diurnal energy partitioning. An independent analysis carried
out using estimates of gross primary production reveals that
the better agreement between observed and simulated latent
heat adopting the plant-specific physiological properties
largely stems from an improved simulation of the
photosynthesis process. Finally, to evaluate the effects of
the crop-specific parameterizations on the ABL dynamics, a
series of semi-idealized land–atmosphere coupled
simulations is performed by hypothesizing three cropland
configurations. These numerical experiments reveal different
heat and moisture budgets of the ABL using the crop-specific
physiological properties, which clearly impacts the
evolution of the boundary layer.},
