Wind is one of the most important components of the Earth-atmosphere system. It facilitates advection of water vapor, heat, aerosols, and pollution, and carries momentum for storms and wind energy. Starting from a background in Doppler lidar systems and basic wind retrievals, Brian 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). One major goal of PECAN was to improve understanding of Great Plains low-level jets (GPLLJs). Brian is using 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 has begun expanding on this work to address observations of GPLLJ moisture advection, comparing against model output from the North American Mesoscale Forecast System (NAM). Past activities include working with lidar groups at NOAA ESRL and NASA GSFC, Raman lidar operations, and performing dual-Doppler lidar measurements.
