ClimaAtmos.jl Release Notes

Main

v0.27.9

v0.27.8

Features

New option for prescribing clouds in radiation

When prescribe_clouds_in_radiation is set to true, clouds in radiation is prescribed from a file (monthly cloud properties in 2010 from ERA5). PR 3405

ETOPO2022 60arc-second topography dataset.

  • Update artifacts to use 60arc-second ETOPO2022 ice-surface topography dataset. Update surface smoothing functions to rely only on spectral Laplacian operations. Update raw-topo gravity wave parameterization dataset. Update interfaces in make_hybrid_spaces to support new inputs using SpaceVaryingInput utility. Include a simple example to generate spectra from scalar variables. PR 3378

v0.27.7

Features

Reproducible restarts for simulations with clouds with RRTMGP

  • Reset the RNG seed before calling RRTGMP to a known value (the iteration number). When modeling cloud optics, RRTGMP uses a random number generator. Resetting the seed every time RRTGMP is called to a deterministic value ensures that the simulation is fully reproducible and can be restarted in a reproducible way. Disable this option when running production runs.

    Note: Setting this option to true is behavior-changing. PR 3382

Bug fixes

  • Update RRTMGP to v0.19.1, which fixes the sea salt aerosol lookup table. Sea salt aerosol is added to the target amip config. PR 3374

  • Fixed radiation diagnostics conflicting with each other. Prior to this change, adding multiple diagnostics associated to the same variable would lead to incorrect results when the more diagnostics were output at the same time. PR 3365

  • ClimaAtmos no longer fails when reading restart files generated with versions of ClimaAtmos prior to 0.27.6. PR 3388

v0.27.6

Features

Ozone model is now a dispatchable type

The prescribe_ozone flag was turned into a type, allowing for prescribing arbitrary ozone concentrations. The two types that are currently implemented are IdealizedOzone (implementing a static profile from Wing 2018), and PrescribedOzone (reading from CMIP6 forcing files).

Aerosol and ozone data can now be automatically downloaded

Prescribed aerosol and ozone concentrations 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.

Bug fixes

  • Fixed incorrect time/date conversion in diagnostics when restarting a simulation. PR 3287

  • Switch to hyperbolic tangent grid stretching, which only requires z_elem and dz_bottom. PR 3260

  • Fixed restarts with radiation and idealized ozone.

v0.27.5

  • Update RRTMGP and allow multiple aerosols for radiation. Note: Don't use sea salt as there is an issue with the lookup table. PR #3264

v0.27.4

  • Add artifact decoding from YAML PR #3256

v0.27.3

  • Add support for monthly calendar diagnostics PR #3235
  • Use period filling interpolation for aerosol time series PR [#3246] (#3246)
  • Add prescribe time and spatially varying ozone PR #3241

v0.27.2

  • Use new aerosol artifact and change start date PR #3216
  • Add a gpu scaling job with diagnostics PR #2852

v0.27.1

  • Allow different aerosol types for radiation. PR #3180
  • Switch from Dierckz to Interpolations. Interpolations is type-stable and GPU compatible. The order of interpolation has decreased to first. PR #3169

v0.27.0

  • Change radiation_model in the radiation cache to rrtmgp_model. PR #3167
  • Change the idealized_insolation argument to insolation, and add RCEMIP insolation. PR #3150
  • Add lookup table for aerosols PR #3156

v0.26.3

  • Add ClimaCoupler downstream test. PR #3152
  • Add an option to use aerosol radiation. This is not fully working yet. PR #3147
  • Update to RRTMGP v0.17.0. PR #3131
  • Add diagnostic edmf cloud scheme. PR #3126

v0.26.2

  • Limit temperature input to RRTMGP within the lookup table range. PR #3124

v0.26.1

  • Updated RRTMGP compat from 0.15 to 0.16 PR #3114
  • Removed the filter for shortwave radiative fluxes. PR #3099.

v0.26.0

  • Add precipitation fluxes to 1M microphysics output. Rename col_integrated_rain (and snow) to surface_rain_flux (and snow) PR #3084.

v0.25.0

  • Remove reference state from the dycore and the relevant config. PR #3074.
  • Make prognostic and diagnostic EDMF work with 1-moment microphysics on GPU PR #3070
  • Add precipitation heating terms for 1-moment microphysics PR #3050

v0.24.2

  • Fixed incorrect surface fluxes for uh. PR [#3064] (#3064).

v0.24.1

v0.24.0

  • . CPU/GPU runs can now share the same yaml files. The driver now calls AtmosConfig via (; config_file, job_id) = ClimaAtmos.commandline_kwargs(); config = ClimaAtmos.AtmosConfig(config_file; job_id), which recovers the original behavior. PR #2994, issue #2651.
  • Move config files for gpu jobs on ci to config/model_configs/. PR #2948.

v0.23.0

  • . Use ClimaUtilities for TimeVaryingInputs to read in prescribed aerosol mass concentrations. This PR is considered breaking because it changes AtmosCache adding a new field, tracers. PR #2815.

  • . Use ClimaUtilities for OutputPathGenerator to handle where the output of a simulation should be saved. Previously, the output was saved to a folder named $job_id. Now, it is saved to $job_id/output-active, where output-active is a link that points to $job_id/output-XXXX, with XXXX a counter that increases ever time a simulation is run with this output directory. PR #2606.

v0.22.1

  • Reduced the number of allocations in the NetCDF writer. PRs #2772, #2773.
  • Added a new script, perf/benchmark_netcdf_io.jl to test IO performance for the NetCDF writer. PR #2773.
