Documentation for GEOS GCM v10

Revision as of 06:47, 19 March 2021 by Mathomp4 (talk | contribs) (→Changelog)

This page lists pages with information on setting up and running GEOS GCM version 10. Earlier and later versions of GEOS may differ in details that, while minor, will require different steps for building and running, so caveat utilitor.

Running GEOS GCM

  • GEOS GCM Quick Start: This page describes the minimum steps required to build and run GEOS GCM v10 on NCCS discover and NAS pleiades. You should successfully complete the steps in these instructions before doing anything more complicated.

  • Hierarchical structure: Below is a (partially folded) view of the Jason 3.0 hierarchy where each node is a GridComp. Some of the nodes are folded (marked with a circle at the end) for clarity - clicking the composite node reveals the sub-nodes.

Changelog

[10.17.0] - 2020-11-25

Zero-diff to previous release: YES

Restart Changes: NO

Major changes include:

  1. The way the model is build has changed. Manage externals is no longer supported. Mepo is now the default and replacement manager for multiple repositories.
  2. Add dependency to turn on BUILD_SHARED_LIBS for NCEP_Shared.
  3. Splits the RRTMG k_g tables into separate files.
  4. Bugfix to change Intel Debug flags for MOM6 and FMS.
  5. gcm_run.j bugfix for tile_hist running MOM6.
  6. Update plots and stats to be consistent with recent CVS tags.
  7. Bugfix for C99 compliance on MacOS.
  8. Updates to CI and other subrepos.

[10.16.3] - 2020-11-02

Zero-diff to previous release: YES

Restart Changes: NO

Changes include:

  1. Added fixture section to components.yaml

[10.16.2] - 2020-10-28

Zero-diff to previous release: YES for default catchment, NO for CatchmentCN

Restart Changes: NO

The latest release is a 0-diff change when running the default catchment. However, it is a non-0-diff change when running CatchmentCN.

  1. Updates to land:
    1. SurfParams: Introduced separate parameter collections for different land model choices that are being cross-checked against the land model choice.
    2. Updates to reproduce Fanwei Zeng’s LDASsa Catchment-CN simulations (science-validated, published) using the 'CN_CLM4' option.
  2. Restructure/Refactor DO_OBIO (see Issue #362)
  3. Add Docker authentication for pulls.
  4. Add logger for NaN detection (at a WARNING level) for QSAT and DQSAT codes.
  5. Make plots/configure portable when using someone else's build.
  6. Allow longer job names for PBS/SLURM.
  7. Update to MAPL.

[10.16.1] - 2020-10-14

Zero-diff to previous release: YES for AGCM, NO for coupled model

Restart Changes: YES (OLRB06RG and TBRB06RG variables added to irrad_internal restart)

Major updates include:

  1. Add TOA RRTMG Band6 (window region) IR diagnostics.
  2. Include new diagnostics for the constraints and new plots for them.
  3. Clean up clumsy logic in GEOS_OpenWaterGridComp.F90 Issue #356
    1. removes the AOIL_COMP_SWITCH
    2. AOIL now properly works with the coupled model (non 0-diff)
    3. maintains 0-diff for uncoupled mode
    4. computations to update the state variables (TW, SW, HW and other internals) are now performed via a call to AOIL_v0.
    5. AOIL_v0 also provides following two options that are turned OFF by default:
      • provide a more gradual decay of diurnal warming as observed in nature: WARM_LAYER_GRAD_DECAY
      • update turbulent heat fluxes after the state variables have been updated: UPDATE_FLUXES_AOIL_SECOND_STEP
  4. Upgrade to MAPL 2.3 with a number of changes listed here.
  5. Fixed regrid_forcing.x and regrid_forcing_esmf.x so they will work with MAPL2.2 and beyond.
  6. Logging config improvements and bugfixes.
  7. Fixed a bug in ExtData when extrapolating on a Leap Day.
  8. Added a deflate and bit shaving option to Regrid_Util.x.
  9. Fix bug with using coarse grids in History and ExtData.
  10. Lowers the amount of jobs used during make -jN install in build.csh to mitigate possible segfaults.
  11. Updated the NCPUs detection in various post scripts to be SLURM-aware.

[10.16.0] - 2020-09-28

Zero-diff to previous release: NO

Restart Changes: NO

The only change in this release is moving back to using int() not nint() in GEOS_Shared/GEOS_Utilities.F90 which may cause crashes if the Debugging flags are on. Nevertheless, this is a non zero-diff change to the gcm.
