Learning outcomes

The aim of the course is to understand the turbulence structure of the atmospheric boundary layer. The course will combine theoretical turbulence theory with practical measurements, which will be evaluated and examined.

After the course the student shall know:

  • the turbulence structure and the flux of energy in the atmospheric boundary layer by using theoretical and experimental results.
  • which types of instruments that can be used in micrometeorological studies, how they work, and how they shall be mounted in the field.
  • how to perform turbulence and profile measurements.
  • how to evaluate turbulence measurements using the eddy-correlation technique and the spectral method.
  • to quantify the resulting fluxes using different filtering methods, trend corrections, and coordinate transformations.
  • how to apply instrument specific corrections.

Content

Advances turbulence theory and results from many different field experiment made in the atmospheric boundary layer. The energy exchange between the atmosphere and the earth’s surface, including radiation processes. Different techniques for measuring turbulence and profiles of temperature, wind, humidity and carbon dioxide. Evaluation of turbulence statistics using the eddy correlation and spectral method such as variances, co-variances, standard deviations and higher order moments that appears in the turbulent energy budget. Investigations of the final fluxes using different filtering methods, trend corrections, coordinate transformations (horizontal and vertical) and instrument specific correction such as flow distortion, cross wind correction and Webb correction. Spectral analysis of turbulence data. The analysis will made in MATLAB.
