Abstract:

The University of Wisconsin Volume Imaging Lidar was modified to increase the laser repetition rate from 30 to 100 Hz and to increase the resolution and dynamic range of the recorded signals. The modified system was used to observe cold air flows over Lake Michigan during the winter. These data, analyzed with improved algorithms for measuring wind velocities from the motions of aerosol inhomogeneities, have provided spatially resolved velocity, divergence and velocity maps with a spatial resolution of 250 meters covering areas of greater than 50 square kilometers.
