Brian has a wide range of experience with a variety of lidar systems and their applications. Starting from a background in Doppler lidar systems and basic wind retrievals, he is now applying the technology to mixed layer height retrievals as well as boundary layer events from the Plains Elevated Convection at Night (PECAN) field campaign (https://www.eol.ucar.edu/field_projects/pecan). Brian has also been involved in numerous other meteorology and air quality campaigns, participating in all steps from mission planning to deployment and scientific analysis.
One major goal of PECAN was to improve understanding of low-level jets (LLJs). Brian has used PECAN’s diverse suite of remote sensing and in situ instruments to study LLJ interactions with the boundary layer from a wind, stability, and turbulence profiling perspective. He is now expanding on this work to investigate observations of mesoscale moisture transport, comparing against model output from the Rapid Refresh (RAP) model analysis and Weather Research and Forecasting (WRF) model forecasts. Past activities include working with lidar groups at NOAA ESRL and NASA GSFC, Raman lidar operations, and performing dual-Doppler lidar measurements.
