                       Module: GEOSagcm
------------------------------------------------------------------------------
1. A bug fix in RRTMG shortwave found by Max that will fix the SW Albedo issues Gary has seen in x0029 (Land & Radiation Consistency)
2. An update in FV3 that allows us to use the non-monotonic advection schemes for momentum and thermodynamic 
   variables without any degradation in edge effects, plus the truly linear PPM schemes in the sponge layers.

Restart Changes: none

==========================================================================
06Dec2017, Takacs,    CVS Tag: Icarus-3_2_p5 (non-zero diff to Icarus-3_2)

__Nov2017, Takacs,    CVS Tag: Icarus-3_2 (zero-diff to Icarus-3_1 when NOT running Brown Carbon)
                       Module: GEOSagcm

3) Changed BKGAVE default to 0 (from 2/3 * CORRECTOR_DURATION).   (non-zero diff)
   A better approach is to use:  IAU_DIGITAL_FILTER: YES

Restart Changes: none

==========================================================================
__Nov2017, Takacs,    CVS Tag: Icarus-3_1 (zero-diff to Icarus-3_0 when NOT running NewLand)
                       Module: GEOSagcm
------------------------------------------------------------------------------
1) Implement Code to enable option for running NewLand


==========================================================================
04Oct2017, Takacs,    CVS Tag: Icarus-3_0 (non-zero diff to Icarus-2_0_p1)
                       Module: GEOSagcm
------------------------------------------------------------------------------
1) Implement R8 version of FV3 VLAB p3 dynamics. Note, current R4 version loses Dry-Mass. R8 version conserves.
2) Updated Single-Moment Physics (MOIST Processes)
3) AGCM now runs RRTMG Shortwave Radiation and Chou-Suarez Longwave Radiation by default (NOTE: cannot use old solar_internal restarts)
4) Implement cubic time-interpolation option for MKIAU in REPLAY (Default: Linear)
5) Updates to MAPL_Base and MAPL_cfio
6) Updates to QuickPlots
7) Implement bugfix to cloudnew.F90 as in Icarus-1_0_p2
8) Changed Dry-Mass value in rs_scale.F90 from 983.24 mb (MERRA-2 value) to 983.05 mb due to use of GMTED topography.
   Mean TOPO difference:  1.58436898227561 meters
   Note: 983.05 mb is very similar to value based on ERA-Interim data.
9) Modified GEOS_TurbulenceGridComp.F90 with more REAL*8 code to improve Dry-Mass Conservation
10) Due to updated FVCORE, GWD BGSTRESSMAX Default changed from 1.2 to 0.9 for 72-levels (Note: 132-levels probably requires re-tuning).

NOTE:  Regular REPLAY to itself FAILS under certain Predictor/Corrector configurations.
      (Reason UNKNOWN)  P3_C6 and P0_C1 seem to work properly.

Restart Changes: YES
                 RRTMG requires new solar_internal restart.
                 Simply delete old restart, and bootstrap new RRTMG restart.

Running Icarus 3.4

  • Icarus 3.4 Quick Start: This page describes the minimum steps required to build and run GEOS-5 Icarus 3.4 on NCCS discover and NAS pleiades. You should successfully complete the steps in these instructions before doing anything more complicated.

Icarus 3.4 Documentation

  • Hierarchical structure: Below is a (partially folded) view of the Icarus 3.4 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.
