| dc.description.abstractEn | The net flux of carbon dioxide between soils and the atmosphere is dominated by soil respiration, one of the largest CO2 fluxes in the carbon cycle. Recent studies place the magnitude of this flux somewhere between 68 and 98 Pg C yr-1 at the global scale and indicate that it has steadily increased over recent decades. More robust estimates of global soil CO2 fluxes are desirable and could be obtained from the atmospheric budgets of other tracers such as, carbonyl sulfide and the oxygen isotope composition (´18O) of atmospheric CO2 and soil water. However, the partitioning of photosynthesis and soil respiration using these tracers hinges on a better understanding of how soil micro-organisms modify the atmospheric concentrations of CO18O and COS at large scales and how to represent these new tracers in land surface models. Within this presentation we will demonstrate how multi-tracer datasets and evolving models can constrain the parameterisation of key processes in land surface models and help tackle the problem of equifinality in simulations predicting the land surface response to recent and future changes in climate. | |
