Paper Abstract
Since 2006 different remote monitoring methods for mixing layer height have been operated in Augsburg. One method is
based on eye-safe commercial mini-lidar systems (ceilometers). The optical backscatter intensities recorded with these
ceilometers provide information about the range-dependent aerosol concentration; gradient minima within this profile
mark the tops of mixed layers. A special software for these ceilometers provides routine retrievals of lower atmosphere
layering. A second method, based on SODAR (Sound Detection and Ranging) observations, detects the height of a
turbulent layer characterized by high acoustic backscatter intensities due to thermal fluctuations and a high variance of
the vertical velocity component. This information is extended by measurements with a RASS (Radio-Acoustic Sounding
System) which provide the vertical temperature profile from the detection of acoustic signal propagation and thus
temperature inversions which mark atmospheric layers. These SODAR and RASS data are the input to a software-based
determination of mixing layer heights developed with MATLAB.
A comparison of results of the three remote sensing methods during simultaneous measurements was performed. The
information content of the ceilometer data is assessed by comparing it to the results from the other two instruments and
near-by radiosonde data.
