Abstract

A micrometeorological field experiment was performed within the frame of the STINHO-project (structure of turbulent transport under inhomogeneous conditions) at the boundary layer field site of the Meteorological Observatory Lindenberg of the German Meteorological Service (Deutscher Wetterdienst) in the summer of 2002 in order to investigate the interaction of thermally heterogeneous surfaces with the turbulent atmosphere. The intention was to compare conventional meteorological point and vertically integrated measurements with area-covering air flow observations and numerical simulations. To observe horizontally variable flow and temperature fields above a heterogeneous land surface, simultaneous acoustic methods (travel time tomography), optical observation methods (IR-camera and line-integrated scintillometer-measurements), as well as the airborne measurement system Helipod were used. The data set will be applied in future to validate large-eddy simulations adjusted to the area of investigation.
