The position will be associated with the Horizon2020-funded project FORCeS (Constrained aerosol forcing for improved climate projections). FORCeS strives towards reducing the uncertainty in anthropogenic aerosol forcing, which is crucial for determining the actions needed to reach the Paris Agreement. SU is coordinating the project, which is a collaboration between 20 European partners.
The overarching goal of this post-doc project is to investigate emergent constraints on climate sensitivity, i.e. to use observations to define a plausible range of a measurable quantity that is related to climate sensitivity, thereby providing an indirect constraint on the latter.
A number of emergent constraints have been suggested and discussed in the literature, and in this project a critical and constructive evaluation of the emergent constraint method is called for.
This may include investigation of possible ways of combining emergent constraints in a multi-dimensional analysis, accounting for their potential inter-dependence; contrasting large-scale constraints (like those based on major volcanic eruptions or paleo-climate evidence) with constraints more localized in space and time; refining the applicability of regime-specific emergent constraints by recognizing them as constraints on certain processes, in certain regions, rather than of overall sensitivity; and/or defining new constraints based on knowledge of relevant feedback processes or naturally occurring variability in the climate system.
Applicants are expected to formulate a research plan within the realm given, which at employment will be further discussed and developed in collaboration with the project leaders.
The main task is to evaluate, develop and apply emergent constraints of climate sensitivity to current-generation climate models, and assess the implications for near-term climate evolution. The refinement of metrics for ESM evaluation, with the aim of “getting the right answer for the right reason”, is a key component in the evaluation and development of the FORCeS ESMs, and the work will be carried out in close collaboration with other FORCeS partners.
Postdoctoral positions are appointed primarily for purposes of research. Applicants are expected to hold a Swedish doctoral degree or an equivalent degree from another country, in atmospheric physics, meteorology, oceanography, climate science or in a related field.
The degree should have been completed no more than three years before the deadline for applications. An older degree may be acceptable under special circumstances, which may involve sick leave, parental leave, clinical attachment, elected positions in trade unions, or similar.
