v1 Configurations

The objective of the Coupled Model Intercomparison Project (CMIP) is to better understand past, present and future climate changes arising from natural, unforced variability or in response to changes in radiative forcing in a multi-model context.

As E3SM is a new model, it is important for it to be benchmarked using community protocols to establish the scientific credibility of E3SM v1, including its overall climate and hydrological cycle. With this in mind, we decided to perform the CMIP6 DECK simulations (Eyring et al., 2016a) using the low resolution (LR) configuration (~100km atmosphere; 30-60km ocean). The key DECK experiments consist of a long pre-industrial control simulation and two idealized CO2 forcing simulations, as well as historical simulations covering the historical record (1850-2014).

E3SM v1 Low Res Scientifically Verified Configurations

Global RMS errors for CMIP5 models and E3SM simulation (DECKv1b_piControl). The more blue the color the better the model, the more red, the worst it is compared to all others.
