The 2024 WH²yMSIE field campaign brought together a wide range of instruments—on the ground, in the air, and from remote sensors—to study the lowest part of the atmosphere, known as the planetary boundary layer (PBL). This part of the atmosphere is important because it controls how weather and winds behave near the surface. In this project, we focus on a strong case of a low-level jet (LLJ), which is a fast-moving stream of wind near the surface that often forms at night and plays a major role in weather and moisture transport. We look at how different kinds of weather observations—including those from aircraft, weather balloons, ground stations, and wind profilers—can be combined to better understand how these LLJs form and change over time. Early results show that using many types of data together helps us better capture important details like temperature changes, wind shifts, and turbulence near the surface. This case study also helps us identify where current observation systems fall short, and what might be needed for future campaigns. Ultimately, this work will help improve weather models and guide the development of new tools to monitor the atmosphere more effectively.
