Doctoral student student in meteorology (PA2018/4520) Deadline for applications 28 February 2019

Jobb assignment

Clouds containing ice at sub-zero temperatures cover wide areas of the globe. Their phase changes during global warming have been predicted to influence climate change.  Their severe weather, in the form of hail or freezing rain on the ground or on air, causes much damage. Initiation of ice inside clouds is crucial because the numbers of crystals in clouds control the production of snow, freezing rain, graupel and hail. Initiation of ice affects the latent heating and dynamics of clouds.  However, there is much uncertainty about ice initiation.
The work will involve numerical modeling. Lab observations from a partner institution of a new process of fragmentation of ice will be represented. The role of the process will be assessed for individual clouds with our aerosol-cloud models. After validation of the simulations, various analyses will be performed for four basic cloud-types. This will involve coding with FORTRAN 90 in a UNIX environment.

 

Doctoral student in Geobiosphere Science (PA2019/407) Deadline for applications 18 March 2019

Jobb assignment

Respiration in aquatic systems contributes to globally significant emissions of carbon dioxide, but calculations of respiration in the open water (the pelagic) are uncertain. One main source of uncertainty is the conversion factor RQ (respiratory quotient), used to convert measured respiration rates from oxygen units to carbon units. It has long been assumed that this ratio is 1 (one carbon dioxide molecule produced per consumed dioxygen molecule), but new findings suggest that the RQ variations can be large and systematic. As PhD student in this project you will carry out field measurements combined with laboratory experiments to test a number of hypotheses about how spatiotemporal variations in the RQ of lakes are governed by chemical, biological and physical factors. You will apply chemical analytical methods combined with microbial analyses and innovative measurement methods in the field.

We seek a PhD student to the project ‘Understanding the role of freshwater respiration in the carbon cycle – a reconsideration of the pelagic respiratory quotient’, who will be admitted to the research education in Geobiosphere Science at Lund University.Applicants are expected to hold a university degree (preferably MSc. or equivalent) in natural sciences. A degree in subjects like Geochemistry, Physical Geography or Ecology is preferable.
