ACCESS GCM data processing tools
ACCESS Archiver:
The ACCESS Archiver is designed to archive model output from ACCESS simulations. It’s focus is to copy ACCESS model output from its initial location to a secondary location (typically from /scratch to /g/data), while converting UM files to netCDF, compressing MOM/CICE files, and culling restart files to 10-yearly. Saves 50-80% of storage space due to conversion and compression.
Supported versions are CM2 (coupled, amip & chem versions), ESM1.5 (script & payu versions), OM2[-025]. For use on NCI’s Gadi system only.

APP4 (ACCESS Post-Processor v4):
The APP4 is a CMORisation tool designed to convert ACCESS model output to ESGF-compliant formats, primarily for publication to CMIP6. The code was originally built for CMIP5, and was further developed for CMIP6-era activities. Uses CMOR3 and files created with the CMIP6 data request to generate CF-compliant files according to the CMIP6 data standards.
Supported versions are CM2 (coupled, amip & chem versions), ESM1.5 (script & payu versions), OM2[-025]. For use on NCI’s Gadi system only. Designed for use on ACCESS model output that has been archived using the ACCESS Archiver tool.

When to use these tools:
Below is a flowchart of ACCESS simulations, highlighting when and for what purpose to use the above described post-processing tools.
ACCESS Archiver: for use on raw ACCESS model output, to create an ‘archive’ of the model data.
APP4: for use on data that has been archived using the ‘ACCESS Archiver’, to create CMIP6-like structured datasets (‘CMORised data’) that can be used for analysis alongside CMIP6 data from the ESGF.
See ACCESS Data Management for CSIRO-specific workflows using these tools.
