Climatology of wind profile parameter estimates above a growing pine forest

The Department of Meteorology of Freiburg University is managing a microclimatological experimental site in a Scotch pine forest (Pinus silvestris L.) near Hartheim/Rhine in southern Germany. Measurements have been taken since the early seventies. The investigations at this measuring station also encompass recordings of wind direction and wind speed. The mean hourly wind speed values, measured in five heights above the trees, have now been recorded for ten consecutive years. An analysis of these records follows.
