Postdoctoral fellow in Aerosol-Cloud-Climate Interactions

At the Department of Meteorology (MISU) at Stockholm University we conduct research and education in an international environment within four main areas: Atmospheric physics, Dynamic meteorology, Physical oceanography and Chemical meteorology. In all these areas there is a strong focus on the climate and on processes important for the climate and its development. The department includes some 75 individuals, of which about 35 are teachers and scientists, 25 PhD students and 15 administrative and technical staff. The department is part of the Bolin Centre for Climate Research that, together with other departments at the university covers research of most of the important aspects of the climate system and the Swedish e-Science Research Centre (SeRC), where we together with KTH and other universities develop e-Science tools and infrastructure to promote scientific breakthroughs in climate science.

Project description
The overarching goal of the post-doc project is to investigate how aerosol perturbations propagate to large-scale cloud and climate variables via cloud microphysical properties, and based on this knowledge improve the description of relevant microphysical and dynamical processes in a general circulation model. Previous studies have shown that climate models potentially overestimate the impact of aerosols on cloud properties compared to satellite observations, which could imply that the models give a too strong aerosol anthropogenic forcing estimate. We know that small-scale cloud feedbacks, such as changes in cloud drizzle and entrainment, may explain parts of the discrepancy between observations and large-scale models, but it is not clear how this knowledge should be implemented in models.

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 22 European partners. 

Main responsibilities
The main task is to use large-eddy simulation (LES) to analyze how an aerosol perturbation affects cloud micro- and macrophysical properties, and to use the LES as a tool to evaluate and understand discrepancies between large-scale models, satellite retrievals and in-situ observations. The knowledge will be used to improve the Earth System Model NorESM and the overall effect on clouds and climate will be evaluated. The work will be done in close collaboration with other FORCeS partners. The successful candidate will be able to shape the project together with the project leaders, within this general framework.

Qualification requirements
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.

Assessment criteria
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.

The degree should be in meteorology, oceanography, climate science or in a related field.

In the appointment process, special attention will be given to research skills within the general area of the announced position. Attention will also be given to the ability to work independently and as part of a group.

The applicant should have excellent knowledge of both oral and written English.

PhD students may apply for the position if they expect to receive the PhD degree before the starting date of the position.

Terms of employment
The position involves full-time employment for a maximum of two years, with the possibility of extension under special circumstances. Start date 1 April, 2022, or as per agreement.

Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
