Notes from Aug 09, 2006
The primary goal of this meeting was for Dunne to provide a tentative assessment of ESMDT activities in the last quarter in preparation for a presentation on same to the Science Council.
Progress towards ESM - John D
- Dynamic ecology and biogeochemistry that does not "break" radiative
and hydrological cycles
- Initialization of carbon system
- ESM has to "wait" on CM development - code and simulation
- ESM simulation depends on CM simulation
- ESM response depends on human activities
ESM2.1 strategy - see white paper
- Code frozen by June 1 - found problems on land side
- Returning land model
ESM3 and "ESM3 enhanced" models described in white paper
Update on what added on ocean biology side
- Explicit zooplankton
- River fluxes of DIC, Alk, NO3
- CaCO3 sedimentation
- NO3 atm fluxes
- Fan iron fluxes
- Working on N/P cycling tuning, 4 type shortwave surface fluxes
Update on land
- Mainly work on SM2.1
- Revision of radiative transfer in canopy - fixing formulation error
- Carbon initialization studies show - large coupling shock using
offline models (soil), historical land use beginning 1700 gives large
shock, issue of initialization of control and historical runs
- Fixed namelist and PP run went 30 years
Interactions with other teams and Modeling Services
- LM3 code - LMDT
- 4 band shortwave albedo - Modeling Services, impacts other teams
- Regression test suite on ESM as it is being developed - Modeling
Sevices (Fei?)
What is status of science?
- We apparently can run ESM with climate remaining stable - no flux
adjustments
- Prototype ran for 237 years
What are steps involved to get successful run?
- Mixed layer ocean - atmosphere model tests of land model
- Initialization of land model
- Development of ocean biology and initialization
