CESM Chief Scientist Gokhan Danabasoglu
Marysa is a Ph.D. candidate in Atmospheric Sciences at the University of Washington. Marysa’s research seeks to understand how the atmosphere responds to perturbations in the land surface, what surface processes contribute most to the atmosphere, and how land-atmosphere coupling varies regionally. A land surface model such as the Community Land Model (CLM) does not readily facilitate the necessary model analyses. Many critical land surface processes that affect the atmosphere (e.g., surface albedo, evaporative resistance) are the modeled outcome of complex parameterizations. They cannot be easily prescribed or changed to specified values so as to assess the atmospheric response to a known surface perturbation. To solve this problem, Marysa developed a simplified land surface model (SLIM). Her model provides a computationally efficient yet scientifically robust framework to analyze land–atmosphere interactions. SLIM will be made available to the CESM community.
Adam is a Ph.D. student in the School of Marine and Atmospheric Sciences at Stony Brook University (SBU). He spent some time at NCAR through an Advanced Study Program Graduate Student Fellowship working with Peter Lauritzen. Adam’s research focuses on understanding the convergence characteristics of global models, including CAM, which is particularly important as global models become capable of running at higher horizontal resolutions due to continued increases in computer power. Adam co-developed (with Peter) a new physics grid implementation within CAM, which offers to improve long-standing convergence issues in climate simulations, as well as additional enhancements to the Spectral Element dynamical core in CAM. Adam is also collaborating with scientists in the LIWG to apply variable resolution techniques to improve simulations of the surface mass balance of the Greenland Ice Sheet.
