Impact

Through CARES we aim to deliver a holistic re-assessment of natural marine sulfur emission on the atmosphere and climate, as well as improved and constrained mechanisms for the oxidation of DMS and CH3SH.

Our perturbed parameter ensembles (PPE) workshop offers an opportunity to rapidly impact the laboratory community within the first year of the project. We will write up the outcomes of this workshop to highlight the “known unknowns”, helping to focus laboratory studies outside of CARES to resolve these unknowns.

CARES will have impact on the field work community by providing a template for process-based measurement projects that are informed by PPE modelling from the outset to optimise experimental design.

CARES will also impact the climate and Earth system modelling communities. Working closely with the UKESM team in particular, we will leverage the international userbase of the UKCA component of UKESM to deliver improvements to the configurations of the UKCA they use for climate modelling.

CARES will also lead to major advances and outputs in high impact publications through the adoption of our chemistry schemes into the Earth System Models of our Project Partners, and the UKESM model for the next phase of the Coupled Model Intercomparison Project (CMIP7).

These advancements include quantifying and reducing the uncertainty in the natural marine aerosol background and hence anthropogenic radiative forcing from sulfur, and the improved quantification of future carbon budgets simulated with next generation ESMs.
