The IGBP-AIMES Project

Analysis, Integrtation and Modelling of the Earth System
• Directions:
• Synthesis of the findings from the different IGBP Projects into a coherent framework
• Coupling between the biogeochemical system and the physical climate system (link between IGBP and WCRP)
• Coupling the natural system with the human system (link between IGBP and IHDP)

Institutional Networking
• Better involve research institutions that have a broad approach in Earth System Research
• These institutions could provide resources in support of IGBP science.
• AIMES would offer to these institutions a platform to develop joint projects, discuss scientific achievements, develop a vision for future research, organize specific activities such as model intercomparisons, develop educational activities (PhD and post-doc program) etc.
• This network would establish links between developed and emerging countries.

Analysis, Integrtation and Modelling of the Earth System
• Specific Actions related to GEIA:
• From stactic (natural) emission inventories to emission models to be coupled with chemical-transport atmospheric models.
• From static (anthropogenic) model inventories to emission models that account for the human dimension (economic models)
• From Carbon-Climate to Carbon-Chemistry-Climate modeling (and intercomparision).
• Dynamic vegetation models
• Scenario activities

• Integrated history of natural and human system change: spatially explicit, mapped globally
• Scale: last 8000 years, with higher spatial and temporal resolution for the last 300 and 100 years
1. Test coupled biophysical-human models against the integrated history
2. Project future of the ‘human enterprise’ with more confidence and skill, based on models tested against the integrated history

Conclusions
• AIMES should be different from GAIM. It will have to define themes (analyses, modeling) that involve many of the IGBP Projects, and has interfaces with WCRP, IHDP and Diversitas.
• It should remain focussed on a limited numbers of initiatives, but these should be challenging and at the frontier of what is possible.
• The focus should be on the science.• The involvement of emerging countries is key.
