Recommended CAM tuning and dycore parameters for use in
CAM3_5_07 (ACMEv0)
1.1 Source Code for both runs
For complete details, see Appendix 1 below
CESM1_2_rel06 (same as CESM1_2 release)
CAM updated to CAM 5_3_07 (which has homme1_3_33 and the needed IBM xlf RRTMG
bugfix)
Source code changes applied to svn checkout ( see svndiff.out )
● For Mira: add compiler option to Macros: -qxlf2003=polymorphic
● Patch so CAM-SE can use the physics package energy fixer
● CICE bugfix involving “aice” (for coupled only)
● Optional, non-answer changing patches:
Source code changes in SourceMods in case directory:
● micro_mg1_0.F90 (to change “Dcs” in source code)
● progseasalts_intr.F90 (to change sea salt scalefactor=0.65)
● ice_dyn_evp.F90 CICE change from Mat and aice bugfix
● POP_HaloMod.F90 optional. support for new POP decompositions
1.2 Dycore and Physics settings recommended for all resolutions:
Set in ‘user_nl_cam’, except for DCS, Sea salt scalefactor and zmconv_tau.
NE120 Physics settings (from NE120 tuning)
convection:
● cldfrc_rhminl = .91 ! ne120 tuned value
● cldfrc_dp1 = 0.025 ! default 0.10
● zmconv_c0_lnd=.0035
● zmconv_c0_ocn=.0035
● zmconv_tau = 3000 ! requires source code change in zm_conv.F90
● dcs=600e-6 ! requires source code change in micro_mg1_0.F90
aerosols:
● soil_erod = '/your/system/path/inputdata/atm/cam/dst/dst_1.9x2.5_c090203.nc'
● SEASALT:scalefactor=0.65 ! NCAR default: 1.35
● dust_emis_fact = 1.05D0 ! NCAR ne30 default: 0.55
NE30 Physics settings for CSSEF project (atmosphere test-bed )
● Use same as NE120. See Forcing and I/O additions below
NE30 Tuned physics. (for F1850 RESTOM=0)
● Use NE120 aerosol tunings
● dtime=1800 (ATM_NCPL=48) ! NCAR default, set in env_run.xml
● cldfrc_rhminl = .8975 ! NCAR default
● cldfrc_dp1=.035 ! tuned for RESTOM=0
● zmconv_c0_lnd=.0035 ! NE120 values
● zmconv_c0_ocn=.0035 ! NE120 values
● zmconv_tau = 3600 ! NCAR default
● dcs=400e-6 ! NCAR default. hardcoded in micro_mg1_0.F90
Dycore settings for all resolutions:
energy_fixer = -1 ! requires CAM physics energy fixer enabled via source code patch
! in physpkg.F90
statefreq = 1200
! optional: turn on interpolation of history output:
! interpolate_analysis = .true.,.true.,.true.,.true.,.true.,.true.,
! interp_gridtype = 2 ! to interpolate to a Gauss grid. (default is FV fixed)
! dycore settings
se_ftype=0
rsplit = 3
qsplit=1 tstep_type=5 ! add tstep_type to CAM’s namelist_definition.xml file.
vert_remap_q_alg = 1 ! I think this is the default, may not be needed
Dycore resolution specific settings:
! ne30 (1 degree):
se_nsplit=2 hypervis_subcycle=3 ! dtime=1800
se_nsplit=1 rsplit=2 hypervis_subcycle=3 ! dtime= 600. rsplit=3 is ok, just slower
nu=1e15 nu_div=2.5e15 nu_q=1e15 nu_p=1e15
! ne120 (¼ degree):
se_nsplit = 4 hypervis_subcycle=4 ! dtime=900
se_nsplit = 3 hypervis_subcycle=3 ! dtime=600
nu=1e13 nu_div=2.5e13 nu_q=1e13 nu_p=1e13
ncdata = '/gpfs/mira-fs0/projects/ClimEndStation/taylorm/cam_ic/f1850c5_m3.cam.i.0007-01-01-

bnd_topo = '/gpfs/mira-fs0/projects/ClimEndStation/taylorm/cam_ic/USGS-
gtopo30_ne120np4_16xconsistentSGH.nc'
! ne240 (1/8 degree):
se_nsplit = 5 hypervis_subcycle=4 ! dtime=600
nu=1e12 nu_div=2.5e12 nu_q=1e12 nu_p=1e12
! armx8v3 (1 degree -> 1/8 degree):
se_nsplit = 5 hypervis_subcycle=8 ! dtime=600
nu=8.0e-8 nu_div=20.0e-8 nu_p=8.0e-8 nu_q=-1 (uses 8.0e-8)
CSSEF runs: all resolutions (NE30 and var-res) will use the NE120
physics tunings and physics timestep (dtime) as above with the
following additions:
ne30 (1 degree) Free-Running simulation for January to August 2011
Use the same settings for physics as high resolution runs
RUN_STARTDATE = “2011-01-01” ! set in env_run.xml
dtime=600 ! set in env_run.xml by ATM_NCPL=144, “dtime” in user_nl_cam will be ignored

Tunings used by the High-Res and CSSEF projects

Our first attempt to capture the provenance of the B1850 ACMEv0 simulation is here:

tar files associated with the B1850 simulation

The V0 simulations were run with CESM1_2_rel06 (the ACME repo starting point, tag v0.0), upgraded to CAM5_3_07, and then with additional minor bug fixes. These upgrades are captured on the ACME maint-0.0 branch, tag "v0.0.1". Recently, Titan was upgraded and the updates necessary to run on Titan. the maint-0.0 branch was further updated so that the code can run on Titan as of 8/2014. These latest updates are tag "v0.0.2". See Branch, Tag, and Version name conventions
