EPREM Widespread SEP Events: Point observers

This record includes compressed archives of selected files from all simulation runs described in "Quantifying the Effects of Parameters in Widespread SEP Events with EPREM" by Young and Poduval. Each archive contains the following:

1. The runtime configuration file (eprem.cfg)
2. All point-observer output files (as NetCDF files with suffix .nc)

You can extract the archived datasets using commonly available utilities

• Files ending in .tar.gz can be uncompressed by running tar -cvzf [filename] (e.g., tar -cvzf baseline.tar.gz). This requires the tar and gzip utilities, which are standard on most *nix operating systems, such as Linux distributions and macOS.
• Files ending in .zip can be uncompressed by running unzip [filename] (e.g., unzip baseline.zip), which may require installing the unzip utility. Alternatively, many popular operating systems with a graphical interface, such as Windows and macOS, support opening a .zip file by double-clicking on the icon.

The EPREM source code is publically available. The point-observer files were produced by EPREM v0.14.0, which is available as a release tag from the source-code repository. The distribution archive is available from the companion record zenodo.org/records/17195904. Instructions on building the EPREM executable are available via the public repository or the distribution archive.

The basic command used to run each simulation, from within the directory containing the corresponding runtime configuration file, was mpirun -n 50 [path/to/executable] eprem.cfg. Note that this will print a runtime log to the screen and will generate hundreds of gigabytes of output data. In order to print the runtime log to a file, the authors recommend redirecting output as follows: mpirun -n 50 [path/to/executable] eprem.cfg &> output.log, which will print the runtime log to a file named output.log in the working directory. It is also possible to replicate these simulation runs on fewer processors at the cost of longer run times.
