In this contribution we analyze a data-set from a recent field experiment in a sparse Lodgepole Pine Stand in Northern British Columbia, Canada. Data was sampled using a vertical array of ultrasonic anemometers at the Kennedy Siding' tower (55° 06' 43''N, 122° 50' 23''W). The stand surrounding this tower has a mean canopy height of h = 16 m, a low canopy cover of only 24.3%, and a leaf area index of 1.38. The site is located in flat terrain and the fetch in all wind directions extends to at least 1 km. Eight Campbell Scientific CSAT-3 ultrasonic anemometer thermometers were simultaneously operated at 10 Hz at different heights (z/h = 0.16, 0.44, 0.68, 0.87,1.06, 1.25, 1.56, and 1.96) over one month in August / September 2007. These measurements were complemented with a profile of fine-wire thermocouples to retrieve an accurate vertical profile of mean temperatures.
From this data-set, ensemble average profiles of different higher-order turbulence statistics and quadrant analysis measures have been calculated. The poster will feature a panel of selected vertical profiles stratified into different overall forcings based on the sensible heat and momentum flux measured at tower top (z/h = 1.96). The discussion enlightens some specific features of a sparse forest canopy by comparing the results with literature values from dense canopies.
