The NASA/GSFC Scanning Raman Lidar (SRL), together with other lidars, was deployed at the Homestead field site during IHOP. 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 has been collected during IHOP. 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, dust/gust fronts, gravity and bore waves, drylines and many other mesoscale features. Recently, a new method is being developed for measuring liquid water content profile. The SRL was also compared to several of the instruments deployed in IHOP.

We plan to present a summary of the SRL measurement in IHOP. This will include data from undular bore conditions, Gust fronts, drylines and a comparison of the SRL data with other instruments.
