| Zusammenfassung |
| During the FLUXPAT campaign in 2008 the MetAir Dimona research aricraft
performed several fligths above a patchy, agricultural dominated landscape near
Juelich/Germany. Main focus of the measurements are variability of water vapor
and CO2 and their turbulent fluxes in the atmospheric boundary layer close to
the ground. Flights took place at changing levels between 80m and 400m above
ground in legs parallel and perpendicular to the prevailing wind. Agriculture in
the region is dominated by two different crops: sugar beet and wheat.
Simultaneous to the flights measurements at the ground took place to determine
evapotranspiration and CO2 uptake of the crops, single plants and the soil
below.
We will present analyses of the airborne concentration and flux measurements,
identify organized structures or at least parameters characterizing them. These
parameters are related to external parameters as wind, stability, boundary layer
depth and and surface fluxes and their distribution on the ground. |
