Abstract

The DFVLR infrared Doppler lidar has been equipped with an on-line data system. It utilizes a peak-finder circuit, a transient recorder, and a microcomputer to evaluate a certain wind quantity from temporal series of measured radial wind components. By means of one example, i.e., the determination of vertical wind profiles in the atmospheric boundary layer, the efficiency of the on-line data system is shown. It takes between 3 and 7 min to derive a profile of wind vectors from the surface up to a 750-m height.
