Abstract
¶This paper describes the configuration of measurement systems operated continuously at the Meteorological Observatory Lindenberg with the aim of constructing combined profiles of wind and temperature – so-called composite profiles – covering the boundary layer with high temporal and vertical resolution. This is required for the forcing of a micro-α-scale model in order to simulate the atmospheric boundary layer structure over a heterogeneous landscape during the LITFASS-98 experiment. The problems of combining measurements of different remote sensing and in-situ systems are briefly discussed. Although the measuring range of individual remote sensing systems is variable, the height coverage of wind and temperature profile measurements by sodar/RASS and two wind profiler radar/RASS complement each other very well. Using a simple merging procedure composite wind and temperature profiles have been synthesized based on radiosonde, windprofiler/RASS, sodar/RASS and tower measurements. Time-height cross sections of hourly composite profiles show considerably more details of the boundary layer structure than simple radiosonde interpolation due to the higher sampling frequency, higher vertical resolution and increased accuracy at the lower levels.
