Entry requirements

120 credits and Turbulence and Micrometeorology, 15 credits. Meteorology, Hydrology and Environmental Measurement Techniques, 15 credits, is recommended. Proficiency in English equivalent to the Swedish upper secondary course English 6.

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.

On completion of the course, the student should be able to:

• 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.

Instruction

Lectures, practical assignments, seminars and project investigation

Assessment

Written examination (5 credits), project investigation (5 credits). To pass requires approved practical assignments and active participation in the seminars (5 credits).

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
