Description

Over the past two years, ARM, in collaboration with the Oliktok Point Site Science team, has deployed unmanned aerial capabilities at Oliktok Point as part of the Inaugural Campaigns for ARM Research using Unmanned Systems (ICARUS) project. This includes several Unmanned Aircraft System (UAS) deployments with the ARM DataHawk aircraft, as well as ARM Tethered Balloon System (TBS) deployments. These deployments have spanned a variety of seasons, ranging between March and late October and have resulted in the collection of measurements of atmospheric thermodynamic state, aerosol properties, turbulence and turbulent fluxes, and ice microphysical properties. In this poster, we will provide an overview of the ICARUS deployments, and provide examples of the scientific pursuits that are being undertaken by the Oliktok Point site science team using the obtained measurements. This includes ongoing efforts to understand the vertical structure of the lower Arctic atmosphere and evaluate the simulation of this environment with a variety of models. Specific topics to be highlighted include the use of these measurements to observe ice microphysical properties and evaluate radar retrievals of these properties; aerosol cloud interactions, including the ability of clouds to redistribute aerosols vertically in the atmospheric column; fine details of the thermodynamic and turbulent structure over a variety of atmospheric and surface states; the evaluation of remote-sensing retrieval products aimed at collecting information over longer time periods; and the evolution of turbulent surface fluxes during sea ice freeze up.
