abstract = {A key question in times of climate change is, how the
biosphere responds to global change and the local land use
management in regard to its carbon cycle. At the present
time, the land surface acts as a sink for an thropogenic
carbon dioxide (CO$_{2}$) emissions. However, additional
CO$_{2}$ recarried out in winter wheat, winter barley, and
in an intercrop mixture during different plant development
stage and at diffrent times of day. A gas analyzer
continuously records the concentrations at a frequency of 20
s$^{−1}$ over a 2 m profile height. We present a
post-processing technique of the measurements (e.g. the
correction of timelags) and show the resulting vertical
profiles as 30-minute averages over height steps of 0.025m.
The profiles clearly show the effects of soil respiration
and photosynthetic carbon uptake within the plant stand,
which vary both during the time of day and during the
vegetation period. Using the Monin-Obukhov similarity
theory, measurements over bare soil and a short plant canopy
were analyzed to check the validity of the elevator
measurements and the raw data processing. It was found that
the derived fluxes of CO$_{2}$, latent and sensible heat,
and momentum correlated well with eddy-covariance (EC)
measurements [...]},
