  • Not zero-diff vs. v17.11.1 for simulations with data assimilation in EASE-grid tile space. Simulations in EASE-grid tile space without data assimilation are zero-diff except for roundoff differences in “tilegrids” and “tilecoord” parameters (ll_lat, ll_lon, ur_lat, ur_lon, dlon, dlat, area). Zero-diff for simulations in cube-sphere tile space with and without data assimilation.

  • Science changes:

    • Support for MODIS-based snow albedo (GEOSgcm_GridComp PR#618).
    • Support for CatchCN ensemble simulations (PR #584, GEOSgcm_GridComp PR#645).

  • Utilities:

    • Re-mapping of restart files (PR #551, GMAO_Shared PR#238, GEOSgcm_GridComp PR#571 and PR#658):
      • New GMAO_Shared utility remap_restarts.py, including fixes to re-mapping of CatchCN restart variables (not fixed for regrid.pl).
      • Deprecated perl script regrid.pl.
      • New GEOSldas utility process_rst.py (replaces process_rst.csh).
      • Re-mapping of LDASsa-formatted binary restarts is no longer supported.
      • Trivial non-zero diff changes (presence/absence) in optional restart fields (TSURF, WW, FR, CQ, CH).
      • Major cleanup of Catch[CN]-related routines for processing restarts in GEOSldas and GEOSgcm_GridComp.
      • Updated ldas_setup to python3.
    • Further cleanup and reorganization of EASE grid utilities and make_bcs (PR #586, GEOSgcm_GridComp PR#601 and PR#634):
      • Unified source code for EASEv1 and EASEv2 utilities, which causes roundoff differences.
    • Reorganized and added utilities in LDAS_App (PR #569):
      • Added matlab routines for generation of Tb scaling parameters, mwRTM parameters, and climatology files.
      • Added LADAS-related utilities and sample config files, incl. option for ensemble forcing of LDAS coupled to deterministic simulation in Hybrid4DEnVar.
      • Added script for rewinding existing GEOSldas run (PR #606).

  • Interface:

    • Increased character length of string variables to avoid truncation of input file paths/names (PR #574).
    • Changed ensemble member identifier string in HISTORY.rc to “_e[XXXX]” (PR #584).
    • Restored GEOSldas “debug” mode (PR #587, PR #589, and PR #591).

  • Infrastructure:

    • Updated environment, CMake, ecbuild, and MAPL (PR #604):
      • ESMA_env v4.8.0
      • ESMA_cmake v3.21.0
      • ecbuild v1.3.0
      • MAPL 2.33.0
    • GMAO_Shared v1.6.3
    • GEOSgcm_GridComp v1.17.2

  • Documentation:

  • Bug fixes and other minor changes:

    • Fixed units labels of several CatchCNCLM45 restart variables (GEOSgcm_GridComp PR#660)
