CAM-SE AMIP in CESM1
05/23/11 CAM-SE ~1 degree AMIP (1981-2000) compared to obs with CCSM4 settings. This run uses 'aave' for all the remapping files and preind_rhminh=0.68, rhminl=.917, and uses new cam4 phys defaults in CESM1.
05/24/11 CAM-SE ~1 degree AMIP (1981-2000) compared to T85 AMIP run with same CCSM4 settings as T85 (except tunable params, which are as above).
Tuning new settings for HOMME in CESM1
05/22/11 4 year CAM-SE ~1 degree preindustrial run (w/ 2 year spin up) compared to obs with CCSM4 settings with nu_top=3.5e5 instead of 2.5e5. This run uses 'aave' for all the remapping files (else error), and preind_rhminh=0.68, rhminl=.917, uses new defaults in CESM1.
05/22/11 7 year CAM-SE ~1 degree preindustrial run (w/ 5 year spin up) compared to obs with CCSM4 settings. This run uses 'aave' for all the remapping files (else error), and preind_rhminh=0.68, rhminl=.917, uses new defaults in CESM1.
05/22/11 7 year CAM-SE ~1 degree preindustrial run (w/ 5 year spin up) compared to tuned fv09 with CCSM4 settings. This run uses 'aave' for all the remapping files (else error), and preind_rhminh=0.68, rhminl=.917, uses new defaults in CESM1.
05/22/11 7 year CAM-SE ~1 degree preindustrial run (w/ 5 year spin up) compared to tuned t85 preindustrial. This run uses 'aave' for all the remapping files (else error), and preind_rhminh=0.68, rhminl=.917, uses new defaults in CESM1.
High Resolution Runs for tuning
1 year HOMME ~1/4 degree preindustrial run (w/ 1 year spin up) compared to obs. This run uses 'aave' for all the remapping files, and climatology ocean dataset. rhminh=0.60, rhminl=.085, close to E balance, TOM and SURF slightly off.
