Biogeochemistry Objective BG-2.2

Measure and model surface-atmosphere exchange of energy, carbon, water and their responses to land use and climate changes

Biogeochemistry Objective BG-2.2 contributes to meeting CEH Science Strategy Challenge II (to identify processes linking physical and chemical changes in the environment with ecosystem responses) through integration of data and models to increase our understanding and ability to accurately predict changes in energy, carbon, and water cycling as a result of change in land-use or climate.

BG-2.2 research aims to:

  • Improve representation and develop and test updated parameterizations of boreal / arctic land-surface processes
  • Assess the impact of bioenergy crops on surface energy, water and greenhouse gas balance and  monitor long-term changes in soil and water. Develop process-based models of water and greenhouse gas exchanges
  • Improve representation and develop and test updated parameterizations of African land-surface processes
  • Derive land-use change from Earth observation
  • Develop new parameterizations of photosynthesis and transpiration for JULES (Joint UK Land Environment Simulator) and test against tower flux data
  • Develop and test methane flux models and test against tower flux data and Earth observation data
