Data Policy
Please familiarize yourself with overall E3SM Policies about the code, new development features, running the E3SM simulations, E3SM data, and collaboration, please read
Specific Policies about data availability
The data from all major campaign simulations is made available to the public after the simulation has been extensively validated and is deemed a ‘Scientifically Validated Simulation” and after the first overview publication from the data is submitted to the peer-reviewed journal. This usually takes a few months time to a year.
The information on all released data and its download can be found at
If you find any problem with the data or have a question, please email
If you are using E3SM data for your research or in a publication, please acknowledge E3SM, see
