CESM Distinguished Achievement Awards

2016: CESM Distinguished Achievement Award

The 2016 CESM Distinguished Achievement Award recipients are Jennifer E. Kay and Clara Deser.

In addition to the regular releases of CESM model versions, the Large Ensemble (LE) represents one of NCAR's of most significant contributions to the US climate research community. The multi-member ensemble of historical and future forcing scenario simulations has proven to be a rich resource for climate and climate change studies. As always with such a large project the end product obscures much of the technical activity and decision-making that is necessary for its success. Jen Kay and Clara Deser were able to provide this management and leadership of the project very successfully. At a scientific level, the utility of the LE cannot be overstated. With this comprehensive set of simulations the climate analysis and modeling community is now able to provide a greater quantification of the uncertainty associated with internal climate variability. Furthermore, the success of the project has attracted a significant contribution of additional ensemble members from member institutions and the use of forcing data to provide downscaling in WRF high-resolution climate change experiments. The LE, though only produced in 2014 and 2015, is highly used and the LE publication has already garnered over 30 citations in the literature.

2015: CESM Distinguished Achievement Award

Keith Moore (University of California at Irvine) has been a key member of the Biogeochemistry Working Group for over 10 years.  In the early 2000's he, Scott Doney and Keith Lindsay designed and assembled the first version of the biogeochemistry component of the ocean model. Keith Moore had worked on several of the parameterizations that were incorporated into this first version of the component. He has been involved in all further developments of the component, and has written many papers using this component. [More...]

2014: CESM Distinguished Achievement Award

Marika’s contributions to the CESM project span 15 years and several versions of the model. Most recently, she served an extended term as the CESM Chief Scientist, helping to shepherd various versions of CESM1 development and inclusion of the model in the recent IPCC Fifth Assessment Report. This progress has been especially noteworthy, because it was achieved during a time of increasing budgetary pressures. After serving a standard two-year term, Marika demonstrated her commitment to the project by selflessly agreeing to remain Chief Scientist for another several months, until a successor could be found.

2013: CESM Distinguished Achievement Award

Phil Rasch, from the Department of Energy Pacific Northwest National Laboratory, is the recipient of the 2013 CESM Distinguished Achievement Award. Phil has made numerous and significant contributions to the development of the community atmosphere model of the CESM project over many years. These contributions actually pre-date the release of the first version of the CCSM. In the 1980s and 1990s, while Phil was a scientist at NCAR, he was involved in the development of the CCM atmospheric models. The first version of CCSM, the Climate System Model 1.0 (CSM1.0) was released in June 1996 and incorporated CCM3.0 as the atmospheric model component. Phil has continued to be active in the development of the atmospheric component for all subsequent CSM, CCSM, and now CESM models.

In recent years, the CESM project has benefitted from Phil’s significant efforts on the CAM5 developments. CAM5 represents a significant advance in global atmospheric modeling developed under CESM's community-based structure, and its innovations represent contributions from many climate and computational scientists and numerous dedicated software engineers. Phil worked tirelessly to marshal this team to thoroughly revamp physics in CAM with state-of-the-science treatments of boundary layer processes, radiation, aerosols, shallow convection, and in fact most of the important atmospheric processes.

2012: CESM Distinguished Achievement Award

Bill Lipscomb is the recipient of the 2012 CESM Distinguished Achievement Award. Bill's contributions to the CESM project began over ten years ago when he joined the Climate, Ocean and Sea Ice Modeling (COSIM) team at Los Alamos National Laboratory as a Postdoctoral Researcher. In his initial years at Los Alamos, Bill made notable improvements to the Los Alamos sea ice model, which is the sea ice component of CESM. In more recent years, Bill has established and led the effort to incorporate a land ice component into CESM. Through Bill's inventive and hard work in this area, the CESM project is now making exciting contributions to our understanding of ice sheet loss and sea level rise. [More...]

2011: David Williamson

David Williamson is the recipient of the 2011 CESM Distinguished Achievement Award. David Williamson is long overdue recognition for his significant contributions to CESM and community modeling at NCAR. His science contributions are particularly noteworthy as more often than not they were breakthrough, innovative research activities for global modeling in general and not just for CESM. Dave is one of the pioneers of the present-day discretization methods for the atmospheric primitive equations used in CESM. He was also heavily involved in addressing the problems of discretization on a sphere exploring the use of geodesic or hexagonal grids. [More...]

2009: Gokhan Danabasoglu

Gokhan Danabasoglu is the recipient of the 2009 CCSM Distinguished Achievement Award. Gokhan has been instrumental in developing every version of the ocean component, starting from CCSM1. With Gokhan as co-chair of the Ocean Working Group, the ocean model component for CCSM4 was delivered on time, with everything incorporated as planned and more. It is our opinion that no one has been more key to this, and past versions of the ocean model than Gokhan. [More...]

2002: Cecilia Bitz, UW and Elizabeth Hunke, LANL

Cecilia Bitz developed a state-of-the-art physical-numerical sea ice model that represents the ice mass balance in terms of a multi-category thickness distribution, and represents the vertical transfer of heat in terms of a multi-level temperature profile for each category of ice thickness.

Elizabeth Hunke helped to develop a new elastic-viscous-plastic (EVP) model of sea-ice dynamics that incorporates an elliptical yield curve representing both shear and normal stresses in the deforming ice. This EVP implementation offers the potential for significant improvements in numerical efficiency when implemented on shared memory computer systems.

2001: Jim Hack, NCAR-CGD

This award is in recognition of Jim Hack's many contributions to the CCSM development. In particular, he has led the effort to define the diagnostics system for evaluating various configurations of the atmospheric component of the CCSM.
