Simulation Data

The E3SMv1 simulation data is available on NERSC HPSS.

All native model output data has also been archived on NERSC HPSS using zstash.

If you have an account on NERSC, you can retrieve the data locally or remotely using Globus.

To download simulation data locally on a NERSC machine:

zstash extract --hpss=<HPSS path in table>

To download simulation data remotely using the zstash Globus interface:

zstash extract --hpss=globus://nersc/<HPSS path in table>

or

zstash extract --hpss=globus://9cd89cfd-6d04-11e5-ba46-22000b92c6ec/<HPSS path below>

Note that the data management tool zstash is available from the E3SM-Unified conda environment. An example of retrieving all cam.h0 (monthly atmosphere output files) between years 0030 and 0049 for the piControl simulation at NERSC locally is demonstrated as below in two steps:

  1. To activate E3SM-Unified environment by:

    source /global/common/software/e3sm/anaconda_envs/load_latest_e3sm_unified_pm-cpu.sh

  2. To retrieve files with zstash command:

    zstash extract --hpss=/home/projects/e3sm/www/WaterCycle/E3SMv1/LR/20180129.DECKv1b_piControl.ne30_oEC.edison "*.cam.h0.00[3-4]?-??.nc"

For more information, refer to zstash usage.

If you do not have access to NERSC, you can download simulation data directly through the NERSC HPSS web interface. Note that this will be slow and inefficient since you’ll have to download the tar files.

v1.LR simulations data has been archived on NERSC HPSS under:

/home/projects/e3sm/www/WaterCycle/E3SMv1/LR

and v1.HR simulations data under:

/home/projects/e3sm/www/WaterCycle/E3SMv1/HR

Scripts are not available to reproduce v1 simulations.

Some original run scripts (the scripts that were originally used to create the simulations) have been archived here here. If a script is not collected here, you can try looking for the provenance run script with:
zstash extract --hpss=/home/projects/e3sm/www/WaterCycle/E3SMv1/<LR or HR>/<simulation_name>/ case_scripts/run_script_provenance/*
