WP3 - Improved constraints on terrestrial processes



Leader : University of Exeter - Prof Peter Cox and Prof Pierre Friedlingstein
Input to Science and Environmental Policy : WP3 - Briefing Paper

Objectives

The overall objective of WP3 is to improve constraints on terrestrial ecosystem processes through targeted model evaluation and development. Extensive use will be made of the new observational datasets derived in WP1.

Specific objectives are to:

  • Assess the role of current and future drought for ecosystems and their cabon stocks in both Mediterranean and temperate regions.
  • Investigate the consequences of greater physiological diversity and adaptability in vegetation models for projections of ecosystem resilience in the face of environmental change.
  • Assess the role of forests as future carbon stores and their contribution to climate-carbon feedbacks and mitigation policies.
  • Assess the significance of species specific emissions of biogenic volatile organic compounds (BVOCs) for atmospheric chemistry and aerosols.
  • Bring these tasks together in a model intercomparison project.
