Results are presented of two large-eddy simulation (LES) runs of the entire year 2012
centered at the Cabauw observational supersite in the Netherlands. The LES is coupled to a …

This paper describes the components and usage of an unmanned aerial vehicle developed
for measuring turbulence in the atmospheric boundary layer. A method of computing the …

Taylors' frozen turbulence hypothesis suggests that all turbulent eddies are advected by the
mean streamwise velocity, without changes in their properties. This hypothesis has been …

We present a novel technique to simultaneously measure wind speed (U) at thousands of
locations continuously in time based on measurement of velocity‐dependent heat transfer …

The literature includes a wide variety of definitions or perceptions of non-stationarity. Non-
stationarity can be expressed in terms of turbulence statistics or variability of the forcing of …

The eddy-covariance method represents the only direct way to measure the turbulent fluxes
of momentum, temperature, trace gases, and particles between the land surface and the …

The spatial structure of smooth-and rough-wall boundary layers is examined spectrally at
approximately matched friction Reynolds number (). For each wall condition, temporal and …

Using the eddy-covariance (EC) method to determine net surface-atmosphere exchange
relies on extensive simplifications of the mass balance concept. Among others, it is assumed …

The spatial structures of turbulent flow in the atmospheric boundary layer (ABL) are complex
and diverse. Multi-point spatial correlation measurements can help improve our …

We present an experimental study on the liquid phase properties in a bubble column. The
reactor, that has a diameter of 40 cm, can be operated in both the homogeneous and the …
