Uncrewed aircraft systems (UAS) or drones continue to gain popularity in atmospheric science due to their ability to provide unique perspectives on atmospheric processes of interest. Over the last decade, I have worked to develop and deploy a variety of UAS around the world to better understand the physics of the lower atmosphere. In recent years, this has included a deployment to the tropical Atlantic to observe the drivers of trade-wind cumulus, a deployment to the central Arctic Ocean to advance our understanding of coupling between the surface and lower atmosphere over a thinning sea ice pack, and a deployment to Wisconsin to observe microscale flows over the Great Lakes and the impact of those flows on local ozone concentrations. In this presentation, I will provide an overview of the platforms and missions and offer some insight into the diverse scientific problems that we are attacking with UAS.
