My research involves using high-resolution or Large Eddy Simulation (LES) numerical models to study the impacts of differences in land characteristics on lower boundary layer (BL). Particularly how surface heterogeneities influence BL structures, convection initiation (CI), and local vorticity enhancement. The features are important for the development of severe weather and I have been involved in the Verification of the Origins of Rotation in Tornadoes Experiment (VORTEX-SE), studying such topics. I am also participating in the Land Atmosphere Feedback Experiment (LAFE), where high resolution observations are being used to better understand longer term BL statistics. I am also involved in our small Unmanned Aircraft System (sUAS) program. We are using the sUASs to obtain very high-resolution observations in the boundary layer. Recently we have used the sUASs to study the 2017 Great America Eclipse, and hurricane Maria, in addition to using them in LAFE and VORTEX-SE. I am also involved in analyzing data from the United States Climate Reference Network (USCRN). In particular, we are creating gridded data analyses with the goal of creating a detailed observationally-based soil moisture product for the public in conjunction with other datasets.?
