Development of the NASA/GSFC Scanning Raman Lidar (SRL) has been in progress for a number of years. The SRL system measures high temporal and spatial resolution profiles of water vapor mixing ratio (in addition to aerosol backscattering and extinction) profiles at night and more recently during daytime. Extensive data sets exist now from several field campaigns and investigations of the atmosphere. These data sets have proven very useful in advancing our understanding of a variety of mesoscale as well as synoptic scale phenomena including atmospheric frontal structures, gravity and bore waves, thunderstorm outflows, drylines and many other mesoscale features. Recent work has focussed on extending Raman lidar measuremnets to those of atmospheric liquid water as well as cirrus clouds.
