The investigator continues studying middle atmosphere chemistry and dynamics by (1) analyzing and interpreting the extensive MesoD dataset on tides and gravity waves, and (2) deploying the Na wind/temperature lidar at the Starfire Optical range to study gravity wave momentum, heat and constituent transport. His dataset covers tidal perturbations in middle atmosphere wind and temperature profiles, gravity wave propagation directions and their relationships to lower atmosphere sources and middle atmosphere winds, airglow gravity wave interactions, and sodium chemistry. The Starfire Campaign focuses on sodium wind/temperature lidar measurements of gravity wave momentum, heat, and sodium fluxes, and the associated mean flow accelerations and cooling rates.

通过(1)分析和解释MesoD大量的潮汐和重力波数据，(2)在Starfire光学范围内部署Na风/温度激光雷达，研究重力波动量、热量和成分输运，继续研究中大气化学和动力学。他的数据集涵盖了中大气风和温度剖面的潮汐扰动、重力波传播方向及其与低层大气源和中大气风的关系、气辉重力波相互作用和钠化学。Starfire项目的重点是钠风/温度激光雷达测量重力波动量、热量和钠通量，以及相关的平均流动加速度和冷却速率。
