ClimaCoupler.jl Release Notes

main

ClimaEarth features

Sea-surface temperature and sea ice concentration data can now be automatically downloaded

Sea-surface temperature and sea ice concentration require external files. Now, a low-resolution version of such files is automatically downloaded when a higher-resolution version is not available. Please, refer to ClimaArtifacts for more information.

A higher resolution land-sea mask is now used and automatically downloaded - PR #1006

A 60 arcsecond land-sea mask constructed from topographic data is now used. Topographic data is automatically downloaded and a land-sea mask is constructed by identifying where elevation is greater than 0. Note, this can lead to misidentification of ocean in some areas of the globe that are inland but below sea level (Dead Sea, Death Valley, ...).

Code cleanup

Output path update - PR #1058

Previously, ClimaEarth simulation outputs were saved in a path experiments/ClimaEarth/output/$mode_name/$job_id/artifacts/. This PR removes mode_name has from this pattern, so output will now be in experiments/ClimaEarth/output/$job_id/artifacts/. Note that any external scripts that assume an output path will need to be updated.

Remove ClimaCoupler.Diagnostics module - PR #953

The ClimaCoupler Diagnostics module had become redundant with ClimaDiagnostics.jl, a package designed to provide robust diagnostics across the CliMA ecosystem. Here we remove ClimaCoupler.Diagnostics and instead use ClimaDiagnostics.

We're able to retrieve most of the diagnostics we want directly from ClimaAtmos and ClimaLand, but also want some that come from coupler-computed quantities, such as F_turb_energy. In this PR we add this coupler quantity to our output diagnostics using the ClimaDiagnostics interface.

This PR also removes the AMIP paperplots function, but this functionality is replaced by the generalized make_plots function.

Remove PostProcessor module - PR #1022

After switching to use ClimaDiagnostics.jl and ClimaAnalysis.jl for our diagnostics, the PostProcessor module is not needed. This PR follows directly from the Diagnostics module removal.

Maintenance

  • Update to JuliaFormatter v2. PR #1024
  • Update CI to use Julia v1.11. Introduce Manifest files for Julia 1.11, in addition to the existing generic Manifests. PR #1026

Various ClimaEarth cleanup - PR #1070

This PR does a few cleanup tasks in the experiments/ClimaEarth/ directory:

  • Update the ClimaEarth README.
  • Delete the viz_explorer.jl, which was previously used to create animations of simulation fields, but is not currently being used. Note that these animations will no longer appear in buildkite output.
  • Move functions in the io_helpers.jl file to the Utilities module and delete this file. This should not change any behavior.
  • Move checkpoint_sims function to the Checkpointer module and delete the user_logging.jl file. This should not change any behavior.
