| Summary: | The lack of adequate near-surface observations of the stable
atmospheric boundary layer spatial structure motivated the
development of an instrumented car for mobile turbulence
measurements. The calibration and validation of the car measurements
are performed using controlled field experiments and a comparison
with an instrumented tower. The corrections required to remove the
effects of the car motion are shown to be smaller and simpler than
the corrections for research aircraft measurements. A car can
therefore satisfactorily measure near-surface turbulence using
relatively low-cost equipment. Other natural advantages of a car,
such as the ability to drive on any road at any time of day or night
and follow the terrain slope, as well as its low cost of operation,
make it applicable to observations of a variety of flow regimes that
cannot be achieved with the usual platforms, such as research
aircraft or networks of flux towers. |
