PhD student in Environmental Science focusing on atmospheric aerosol and cloud processes in the polar region

Updated: about 13 hours ago
Deadline: 15 Aug 2021

at the Department of Environmental Science . Closing date: 15 August 2021.

The Department of Environmental Science is one of the biggest departments at the Faculty of Science. The department consists of four units with more than 170 researchers, teachers, doctoral students and technical/administrative staff from over 30 countries. Research and teaching focuses on chemical contaminants, atmospheric science, biogeochemistry and (eco)toxicology. As an employee at the Department of Environmental Science you will be part of a dynamic environment with research in leading research areas and with a strong international profile.

Research on the Air Research Unit (ACESL) follows an interdisciplinary approach in understanding the composition of air and its influence of climate and human health. The majority of our research activities focus on understanding the life cycle and impact of tiny atmospheric particles known as aerosols. Here we use experimental methods such as field and controlled laboratory-based studies as well as various modelling tools.

Project description
The polar regions on Earth are changing faster than elsewhere which is manifested in a dramatic warming and a loss of sea ice at both poles. The underlying processes of the observed accelerated changes are not fully understood, yet they propagate through the entire global climate system with impacts on weather, ecosystems and geopolitics. Clouds and atmospheric aerosols play a major role in the polar systems and are among the main contributors to the overall uncertainties in projecting future climate.

This PhD project aims to investigate the role of aerosol sources (e.g., local vs. long-range transport), aerosol processing (e.g., removal or atmospheric aging) and their role in forming clouds. The successful applicant will analyse and interpret existing long-term and campaign-based data from various platforms in a context of biogeochemical processes, the state of the ocean, sea ice and atmosphere. This work will give needed input for the improvement of fully-coupled models. Participation at planned field expeditions in the Arctic is possible as well.

The PhD position will be part of the new European Horizon 2020 project CRiceS (​C​limate ​R​elevant interactions and feedbacks: the key role of Sea ​ice​ and ​S​now in the polar and global climate system). CRiceS overarching objective is to deliver an improved understanding of the physical, chemical and biogeochemical interactions within ocean-ice/snow-atmosphere system, new knowledge of polar and global climate, and enhanced ability of society to respond to climate change. As part of CRiceS, the PhD student will join a vivid international research community.

Qualification requirements
To meet the general entry requirements, the applicant must have completed a second-cycle degree, completed courses equivalent to at least 240 higher education credits, of which 60 credits must be in the second cycle, or have otherwise acquired equivalent knowledge in Sweden or elsewhere.

In order to meet the specific entry requirements, for doctoral studies in Environmental Science, at least 45 of the credits at the second cycle must be in one of the natural sciences (Biology, Chemistry, Earth Sciences, Physics, or Meteorology) including a 30 credits thesis project. The applicant should also have 30 credits in other natural science subjects different from the major.

The qualification requirements must be met by the deadline for applications.

The selection among the eligible candidates will be based on their ability to successfully pursue the research education. Special emphasis is put on the applicant’s knowledge and skills within the subject area, ability to express her/himself verbally and in writing, analytical aptitude, creativity, initiative and independence, and a capacity for working together with others. The evaluation will be made based on the relevance of past education and experience, grades from previous university courses (in particular at the advanced level), the quality and ambition of the independent project work, references, a cover letter motivating the candidate’s interest, and interviews.

The candidate must be willing to spend significant time abroad, e.g. to participate at international conferences or to join field campaigns at remote sites.
