ChangeLog Entry

In src/Applications/GEOSgcm_App/ChangeLog:

==========================================================================
19Jun2015, Takacs,    CVS Tag: Heracles-4_0 (non-zero-diff to Heracles-3_0)
                       Module: GEOSagcm
------------------------------------------------------------------------------
1) Added MERRA2-DD option within GOCART Chemistry
2) Implemented CMPOPS (MERRA-1 and MERRA-2) within Quickplot, plus other plot updates
3) Modified Constituent Scaling to Preserve Dry Mass Mixing Ratio
4) Used REAL*8 selectively within Turbulence to preserve Constituent Mass during mixing
5) Added option for Triangular Truncation within MKIAU
6) Corrected subtle error related to REPLAY_Q = NO within MKIAU_GridComp
7) Added feature to write AGCM_IMPORT files during Regular REPLAY.  
   This results in Zero-Diff when using those files to force an EXACT REPLAY.
8) Merged updates from 2nd-Moment Microphysics, tag: t_HR051815_2M_updated
   Merged updates from branch: b_HR051815_donifan as of June 19, 2015
   (default, zero-diff when not used)
9) GMIchem: ExtData.rc is now used to import emissions, replacing Chem_UtilMPread.  
   When GMICHEM is the AERO_PROVIDER, the aerosols now populate the AEROSOLS bundle in the AERO state. 
10) B.Putman's updates to COSP Simulator 
11) M2R12K FV3 Dynamics
12) Convert to NC4 Restats automatically

Restart Changes: none
           Note: Converts to NC4 Restats automatically

Running Heracles 4.0

  • Heracles 4.0 Quick Start: This page describes the minimum steps required to build and run GEOS-5 Heracles 4.0 on NCCS discover and NAS pleiades. You should successfully complete the steps in these instructions before doing anything more complicated.

Heracles 4.0 Documentation

  • GEOS 5 Developer's Guide (pdf)
  • Hierarchical structure: Below is a (partially folded) view of the Ganymed-4_1 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.
