FRCGC Carbon Cycle Component Models: Terrestrial model
•Sim-CYCLE by Itoh & Oikawa (2002)
•20 PFTs without dynamic vegetation
•5 compartments for each PFT
“DGVMization” of Sim-CYCLE
Individual basis model, which explicitly treat 3D forest-structure within 30m x 30m patches
Foliage : biomass, crown diameter, crown depth Stem : biomass, height, sapwood & heartwood diameter Root : biomass
Individual characteristics
--- Shape of crown and stem are approximated by cylinder
DGVM: Dynamical Global Vegetation Model
-> Incorporation of the effect of biome-shift into Sim-CYCLE
FRCGC Carbon Cycle Component Models: Oceanic model
•4-compartment ecosystem model (Oschlies & Garcon, 1998)
•Treatment of carbonate system as recommended by OCMIP
•MIROC 3.2 Intermediate Resolution Version (no flux adjustment)
“borrowed” from the K-1 project
•Atmosphere:
CCSR/NIES/FRCGC AGCM 5.7
T42L20
Online aerosol
•Ocean:
COCO3.4 (developed by CCSR, Univ. of Tokyo)
(0.5-1.0)°×1.4°, 43 Layers + BBL
Atmosphere-Ocean Coupled Model
Participation in C4MIP
• C4MIP: Coupled Carbon Cycle Climate Model Intercomparison Project– Strongly IPCC-conscious– Participants: Hadley (UK); IPSL (France); MPI
(Germany); LLNL, NCAR, Berkeley, Maryland, GFDL (US); CSIRO (Australia); FRCGC (Japan)
– Our “pacemaker”
Kyousei Integrated Synergetic System Model of the Earth
KISSME!
C4MIP Phase 1 Experiment
• Land-atmosphere coupled run– Do not really focus on climate-carbon cycle
interaction– CO2 as a simple tracer with sources and sinks
at the surface (including land use change)– Results due in Feb. 2005

C4MIP Phase 2 Experiment
• Experiments with full coupled model including the ocean (like KISSME)
• In parallel with Phase 1• Protocol yet to be firmly established• “Flying leap” experiments can be its prototype.
– 1%/yr increase of CO2 emission– Experiments w/ and w/o interactions between climate
and carbon cycle– Results due to Feb. 2005?
Preliminary results from a “climate of 20th century” run with the full
coupled model

Summary for Carbon Cycle Modeling
• Preliminary results with land-atmosphere and land-atmosphere-ocean coupled models
• Collaboration with the “sister project” K-1-> tune-up of the coupled climate model
• Participation in C4MIP-> Contribution to IPCC AR4
• Fine-tuning of the carbon cycle components is now being carried out --- Stay tuned!
