Observing and Modeling Arctic System Processes

This presentation is a part of our NSIDC Cryosphere Seminar series and is led by Matthew Shupe, Ola Persson, Amy Solomon, Michael Gallagher, Anne Sledd and Bill Neff The Arctic processes team uses many observational and modeling tools to study physical processes of the Arctic system, including clouds, air masses, boundary layer processes, surface energy balances, and much more. The team is now serving as a scientific link between the National Snow and Ice Data Center and the NOAA Physical Sciences Laboratory. This group presentation will provide an overview of the team's research and an introduction to each team member and their specific interests. Focus will be on topics of high relevance to NSIDC, including dynamic and thermodynamic processes that impact the evolution of Arctic sea ice, atmosphere-surface interactions over the Greenland Ice Sheet, and the application of multi-scale models to understand Arctic cloud formation, among others. Bios: The presenters are all new affiliates with NSIDC as well as being members of the NOAA Physical Science Laboratory. They have worked collaboratively over the past years and decades to address key uncertainties in the Arctic system, advance process understanding, and improve model representations. Among many other topics, their current research interests included the following: Matthew Shupe's research focuses on clouds, radiation, and their interactions with the surface energy budget. Ola Persson studies Arctic cyclones, the atmospheric boundary layer, and atmosphere-surface dynamic and thermodynamic exchange. Michael Gallagher works at multiple scales from surface roughness impacts on turbulent heat fluxes to large-scale circulation drivers of temperature change. Amy Solomon develops and applies multi-scale models to explore clouds and improve sea-ice forecasts. Anne Sledd derives thermal properties of snow and ice, and links these with atmospheric heat fluxes. Bill Neff's research examines atmospheric water vapor transport and its relation to Greenland Ice Sheet melt.
