Running the DP SCREAM Configuration
To obtain scripts to run DP-SCREAM please contact [email protected]. Please understand that DP-SCREAM is currently in beta testing mode and access is required from Peter Bogenschutz at this time. We anticipate an official release to the community around Spring 2022, during which this page will be updated.
All DP-SCREAM scripts are configured to run with grid spacing of 3.3 km in the horizontal (to match the global SCREAM model), with a domain size that was deemed appropriate for that case. Cases that simulate boundary layer clouds (for instance) are generally run with a domain size of 50 km x 50 km, while cases that involve deep convection are typically set up to run with a domain size of 200 km x 200 km.
Note, however, that DP-SCREAM gives you the freedom to run with whatever domain size and resolution you want. Clear instructions on how to change domain size and resolution (and to determine the appropriate time steps) are given in the script header.
All required input data is pre-installed on supported (or commonly run) E3SM machines in addition to the E3SM input data server. Therefore, you should be able to run the DP-SCREAM out-of-the-box regardless of machine used.
You should be running with the most up-to-date version of SCREAM master. Support for older versions of the SCREAM code base is not provided at this time.
