Abstract

Abstract:

CMIP6 is being organized by the World Climate Research Project (WCRP). As one of the institutes participating in the CMIP6, National Climate Center, China Meteorological Administration has three latest version of models to participate in the project through model development in recent years. The models include an Earth system model BCC-ESM1.0 with aerosol and chemistry module, a middle-resolution climate system model BCC-CSM2-MR, and a high-resolution climate model BCC-CSM2-HR. In addition to the DECK and Historical simulations of CMIP6, these models will participate in 10 Model Intercomparison Projects (MIPs) of CMIP6. This paper gives a basic description of these models and their participation in CMIP6, as well as a simple evaluation of Historical simulation by BCC-CSM2-MR, which provide references for users of the experimental data.

Key words: National Climate Center (BCC), BCC-CSM, BCC-ESM, CMIP6, Climate system model (CSM), Earth system model (ESM)
