Project description
Black Carbon lifecycle.

Black carbon (BC) particles formed during incomplete combustion processes influence our environment by being detrimental to human health and may influence the climate on many different scales. This project aims towards forwarding our knowledge about these particles and their lifecycle in the atmosphere, from source to sink. Through better knowledge about their life cycle, we can assess the impact that BC particles have on our environment, both near the sources and in remote locations. The goal is not to learn about every process in detail, but to review the sequence of events during their lifecycle to better identify key processes. For instance, particular interest is given to the interaction between BC particles and clouds.
The research will mainly rest on analysis of long-term observational data, with concurrent documentation of various microphysical properties such as BC concentrations, aerosol size distributions, aerosol optical properties and other supporting information. The main data provider is the Ny-Ålesund research community on Svalbard. The aerosol microphysical data goes back to the year 2000. Data from other stations are also likely to be included in the analysis. Although the main focus is on analysis of large data sets, some small dedicated field work is anticipated in order to compare the results from the analysis with the latest instruments available to characterize BC particles.

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 hp/HEC thesis project. The applicant should also have 30 hp/HEC 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.
