Wind is one of the most important components of the Earth-atmosphere system. It facilitates the advection of water vapor, heat, aerosols, and pollution, and fuels 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 and temperature profiling perspective. Brian has begun expanding on this work to tie in GPLLJ theoretical formulations as well as observations of GPLLJ moisture advection. These studies can be adapted to characterize east coast LLJs as well. Brian also works with ground-based lidar groups at NASA GSFC. Past activities include characterizing Doppler lidar uncertainties and performing dual-Doppler lidar measurements.
