Current Research

Current efforts focus on understanding processes controlling the formation, lifecycle, and climatic influence of Arctic clouds. Clouds play important roles in the climate system, including the modulation of atmospheric radiation and the distribution of precipitation. Specific topics currently being investigated include:

Use of Unmanned Aircraft Systems in Atmospheric Observation: Together with collaborators at the University of Colorado, we are exploring the potential for UAS to obtain critical measurments of the atmosphere, including vertical profiles of key quantities, information on spatial variability of surface and atmospheric quantities and their co-variability, and for sampling difficult-to-reach environments. These measurements have been made across a variety of locations, with Arctic deployments at the Oliktok Point, Alaska facility operated by the Department of Energy.

Aerosol-Cloud Interactions in Arctic Clouds: Cloud radiative forcing and precipitation characteristics are influenced by the particles upon which cloud hydrometeors form. Changes to precipitation rates, cloud lifetime, and cloud thickness can all result from changes to aerosol properties. Using a variety of observational and modeling tools, we are improving our understanding of the physical processes responsible for these interactions, as well as the resulting impact on the influence of clouds on the climate system.

The Role of Various Processes in Arctic Cloud Formation and Lifecycle: Arctic clouds form as a result of a complex web of interacting physical processes, including those related to synoptic scale transport of water and heat, surface fluxes of these quantities, cloud-driven radiation, cloud microphysics, and aerosol properties. Our research involves establishing which of these processes are most important while simultaneously improving our understanding of individual components. This knowledge is crucial for improvement of weather and climate model simulations at high latitudes.

Outreach

Outreach allows researchers to share their work with a broader audience than reached by scientific journals alone. As scientists, we are passionate and excited about the topics we study, but seldom have opportunities to discuss our ideas and research with the general public. In particular, as Arctic scientists it is often challenging to interact with the people living in the environment we study.

Thanks to past funding from the National Science Foundation, several researchers have traveled to Barrow, Alaska to share their research, discuss ideas with the local population, and gain firsthand experiences in the environment which they study everyday. Activities have included discussions with Barrow residents, presentations in local schools, seminars in the "Saturday Schoolyard" seminar series, helping to run summer camps, and more. These trips are meant to both share our knowledge with residents as well as enlighten and motivate researchers.
