Coordination to understand and reduce global model biases by U.S. and Chinese institutions

Recognizing the benefits of such collaborations, representatives of modeling centers from the United States and China held a joint workshop in Beijing, China, on biases in coupled models. The meeting was jointly organized by the Chinese Academy of Sciences and National Oceanic and Atmospheric Administration (NOAA) and involved scientists from major U.S. and Chinese modeling institutions participating in CMIP6. While the U.S. models participating in CMIP6 are widely known, some of the Chinese models are not.

The workshop gave scientists in the United States, and in other countries through this workshop summary, an opportunity to become better acquainted with the development undertaken by the modeling institutions in China. Some of the Chinese models build off component models, such as the ocean, atmosphere, land, and sea ice models publicly available from institutions in the United States or other countries, with varying degrees of heritage and similarities.

The totality of these models offers unique opportunities to compare and understand biases in coupled models when one or more components are replaced.
