ACCESS-ESM1.6
Configuration release:
Configuration release-piControl-2.1
Configuration release-esm-piControl-2.1
Configuration release-historical-1.3
Configuration release-esm-historical-1.3
This is a minor configuration release, and the new configuration versions produce bitwise identical results compared to their previous versions. The changes will affect output filenames and netCDF metadata.
Updates
Change to ocean output filenames in the “standard” output profile to make them compliant with the ACCESS-NRI data specifications #1033.
Fix geospatial_lon_(min/max) and geospatial_lat_(min/max) global attributes for each component in post-processed netCDF output #1020.
Remove incorrect time: bounds attribute from static and instantaneous output variables #1035
How to use
Refer to the Run ACCESS-ESM1.6 instructions. This page includes instructions to get a MOSRS account as a prerequisite to running the model.
Details on the experiments outputs and where to find data are at Published Data - ACCESS-ESM1.6-Configs . Experiments will soon be available to access through the access-nri-intake catalog.
Limitations
High salinity in the Eastern Mediterranean Sea
Ocean age tracer doesn’t reflect true “age” of water, as it was reset to zero at the start of piControl experiments.
Some diagnostics were fixed after experiments had been run. In re-runs of piControl and esm-piControl experiments using the latest executable, ocean age tracer diagnostic are not bit-for-bit identical with published output. In re-runs of piControl experiment, atmospheric CO2 tracer diagnostics are not identical with published output.
Some drift in global water mass over time
Restart files are not backwards compatible with ACCESS-ESM1.5, due to different Land, Ocean BGC and Sea Ice models.
Configurations require a 1-year run length
Known Issues
Land-use Change: There are some unallocated variables representing tiles for land use. This means some land-use fields are not redistributed properly between years. The impact is well within the ensemble spread of the historical simulations.
Occasional failures converting atmosphere output to NetCDF
The model description paper in preparation will provide more details on these Features and Limitations.
