ABSTRACT

The National Center for Atmospheric Research (NCAR) and Montana State University jointly developed water vapor MicroPulse Differential absorption lidar (MPD) that is a significant advance in eye-safe, unattended, lidar-based water vapor remote sensing. We present recent work investigating the impacts of assimilating MPD water vapor profiles for convective precipitation analysis and forecasts with Observation System Simulation Experiments (OSSEs) and Observing System Experiments (OSEs). The results suggest that data assimilation of the MPD improves the precipitation and diurnal evolution of planetary boundary layer (PBL) structure forecasts.
