The atmospheric boundary layer (ABL) is the lowest portion of the atmosphere. This portion of the atmosphere play a vital role in the development of weather events. Traditional surveillance techniques include radar, towers, and balloons. Radars are limited by the surrounding geography, so areas with high elevation variation can cause the transmission to become lost. Towers are structurally limited by their height. Balloons provide measurements at higher altitudes but have no control of its flight path. A small unmanned aerial system (UAS) has the ability to overcome all these obstacles inherently by its own design, and can provide higher temporal and spatial resolution when equipped with proper instrumentation. These key advantages of using a sUAS for atmospheric surveying have seen a growing rise in popularity among meteorologist and researches alike. With the increased use of sUAS for this purpose, there is a need to assess this novel approach. This research investigates the use of sUAS for measurement of thermodynamic and kinematic variables in the ABL, primary temperature, pressure, humidity, and wind speed. In the former case, COTS sensor are used to observe thermodynamic changes in the ABL. In regards to the latter, wind measurements are obtained by two methods. The first method is an indirect approach where wind vectors are determined by the sUAS orientation and response to an incoming flow from a known a flight path. The second method is a direct approach by mounting ultrasonic anemometers to measure wind speed. These methods are compared to ground based sensors and LiDAR. In addition, multiple field observations are conducted. Early evening transitions are observed at the Marena Mesonet Site and Gloss Mountains. A storm observation is also conducted before and after its formation at OSU's Unmanned Aircraft Flight Station.
