Understanding the diurnal and seasonal variations of Nocturnal Low-Level Jets (NLLJs) and their influence on atmospheric constituents is crucial for elucidating regional atmospheric dynamics, air quality, and climate impacts. In this study, we investigate the influence of NLLJs on aerosol and ozone layers in the U.S. mid-Atlantic region using a comprehensive observational dataset from ozone and aerosol lidar profiles. We leverage data from radar wind profilers, ceilometers, and the GSFC Tropospheric Ozone Lidar (TROPOZ) system to characterize NLLJ dynamics, aerosol properties, and ozone concentrations. Through analysis of wind profiles, we examine the diurnal variations and seasonal trends of NLLJs, focusing on their intensity, frequency, and vertical structure. Concurrently TROPOZ ozone lidar data provide high-resolution vertical profiles of tropospheric ozone concentration, allowing for detailed investigation into ozone distribution and its relationship with NLLJs.
