Abstract
This dataset contains output from 35 climate model simulations of the warm early Eocene Climatic Optimum (EECO; ∼ 50 million years ago) and corresponding preindustrial reference experiments. The dataset combines global model output from nine coupled climate models (CESM1.2-CAM5, COSMOS-landveg-r2413, GFDL-CM2.1, HadCM3B-M2.1aN, HadCM3BL-M2.1aN, INM-CM4-8, IPSLCM5A2, MIROC4m and NorESM1-F) that have carried out coordinated simulations as part of the Deep-Time Model Intercomparison Project (DeepMIP). Climatological means and time series data of the respective last 100 model years for a total of 57 atmospheric and oceanic variables are standardised following the CMIP6 data request and CF metadata convention.

| Access rules: |
Public data: access to these data is available to both registered and non-registered users.
Use of these data is covered by the following licence(s): https://artefacts.ceda.ac.uk/licences/specific_licences/CMIP6_Terms_of_Use.pdf When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record. |
| Data lineage: |
Model simulations were performed by eight different modelling groups. Climatological means and time series data were centrally collected at the University Research Data Storage Facility (RDSF) at the University of Bristol. Final compilation and metadata creation for archiving at the Centre for Environmental Data Analysis (CEDA) was performed at the University of Bristol. |
| Data Quality: |
A consistent naming convention for variables, directories, and file names across all models is applied to simplify the comparison of different models and to allow a scripted analysis of the entire database. The list of output variables is a modified version of those proposed in the DeepMIP experimental design. Variable names, units and signs of fluxes follow the naming convention of the Coupled Model Intercomparison Project 6 (CMIP6) data request. Consistent standard names, long names and global attributes are added to the netCDF files following the Climate and Forecast metadata conventions (CF) in version 1.8. All netCDF file have been automatically tested for CF-compliance with the cf-checker utility (https://github.com/cedadev/cf-checker). A z-score for the global mean, minimum and maximum for each model and variable relative to the ensemble median is calcluated to identify outliers.
