CESM Chief Scientists

The Climate System Model (CSM) started in 1994. CSM was renamed in 2000 as the Community Climate System Model (CCSM) to recognize the community of developers, contributors, and users. To reflect its expanding Earth system capabilities, the model was renamed as the Community Earth System Model (CESM) around 2011. Between 1994 and ~1999, the CGD director plus one other senior scientist assumed the lead role in setting the direction and priorities for the coupled system. Since then, a Chief Scientist  has been leading these efforts. Below is a list of CESM Chief Scientists to date:
