ABSTRACT
Lower-tropospheric water vapor measurements are critical for improved understanding and forecast skill of convection initiation and evolution. A relatively new instrument to measure continuous water vapor profiles has been jointly developed by EOL and Montana State University. EOL has three water vapor profiling MPDs (MicroPulse Differential absorption lidars) that will soon be available to the research community. In this presentation, I will describe the MPD system, provide data examples that indicate added value of this measurement system for process studies and discuss relative advantages/disadvantages compared to other thermodynamic profiling systems. I will conclude with a series of data assimilation experiments that have been designed to assess the observational impact of water vapor profiles from these MPDs on the prediction of convective systems.
