Biogeochemistry Objective BG-2.4

Develop model frameworks to predict future impact of environment drivers and their interactions at local, regional and global scales including the quantification of uncertainty

Biogeochemistry Objective BG-2.4 contributes to meeting CEH Science Strategy Challenge III (to Improve predictions of climate change models by incorporating ecological, hydrological and biogeochemical processes) through improvement of model accuracy in the prediction of climate processes, and accuracy of representation of feedbacks of the drivers of climate change.

BG-2.4 research aims to:

  • Develop and support a community land surface model (JULES – Joint UK Land Environment Simulator) to provide the land surface component for Earth System models
  • Develop Bayesian methods for quantifying uncertainty associated with spatial up-scaling of biogeochemical models
  • Develop models for long-term projections of the impact of policy-driven land use change on the greenhouse gas balance in the UK and regionally within the UK

Areas of research

  • Biogeochemical modelling
  • Chemical risk at the catchment scale
  • CHESS - Climate, Hydrology and Ecology research Support System
  • Integrated modelling
  • Quantifying uncertainty

Collaborative research projects

Objective BG-2.4 participates in many collaborative projects. Examples include:

  • Joint UK Land Environment Simulator (JULES)
  • LULUCF – Land Use Change and Forestry component of the Greenhouse Gas Inventory for the UK
  • NSINK – Sources, sinks and impacts of atmospheric nitrogen deposition in the Arctic
  • TROBIT – Tropical Biomes in Transition
