Micrometeorological observations of CH4 and N2O at a managed fen meadow in the Netherlands
Abstract about a research project investigating CH4 and N2O emissions at a managed fen meadow.
Saturation of the large aperture scintillometer
The saturation aspects of a large aperture (0.3 m) scintillometer operating over a 10-km path were investigated. Measurements were made over mainly forested, hilly terrain with typical maximum sensible heat fluxes of 300-400 W m(-2), and over flat terrain with mainly grass, and typical maximum heat fluxes of 100-150 W m(-2). Scintillometer-based fl...

Exploring Scintillometry in the Stable Atmospheric Surface Layer
The main objective of this thesis is to investigate observation methods of heat and momentum exchange and key variables that characterise turbulence in the atmospheric stable surface layer (SSL), a layer defined as the lower part of the stable boundary layer (SBL) where surface fluxes do not change significantly with height. The SBL is often confin...
Ground-based atmospheric remote sensing in the Netherlands: European Outlook
...
This paper describes the contours of a Dutch monitoring and research site for climate change and related atmospheric processes. The station has large benefits for atmospheric science, both in The Netherlands and internationally. It provides a platform for collaboration in this important field, and will provide the routine observations needed to ass...
Radar techniques for identifying precipitation type and estimating quantity of precipitation
Estimation of the statistical error in large eddy simulation results
In the study of the atmospheric boundary layer, Large Eddy Simulation (LES) results are nearly considered to be experimental data. However, where experimental results on turbulent quantities are occasionally accompanied by an estimation of the statistical error in the result, this is not the case for LES results. From the statistical literature met...
Long range scintillometry
In the past years there has been a renewed interest in the use of scintillometers for the measurement of sensible and latent heat flux. This interest is partly invoked by the need to infer the energy fluxes over areas that match in size with satellite pixels or the grid of a numerical model. In this respect it is of importance to exploit the path l...

The practical application of scintillometers in determining the surface fluxes of heat, moisture and momentum
This thesis has collated one review chapter and five experiments concerned with addressing the question, 'how successful is the scintillometer method in determining the surface fluxes of heat, moisture and momentum and under what circumstances does it appear to fail?' Answering this question is important as a workable scintillation method provides ...
