PhD candidate atmosphere – biosphere modelling of nitrogen components
Do you want to contribute to better understand how nature areas in The Netherlands are exposed to nitrogen components? Would you like to obtain a PhD at a special institute where science, modelling and application come together? Then make this vacancy your new job and apply immediately.
The Faculty of Science Leiden and Institute of Environmental Sciences (CML) are looking for a PhD candidate
The Institute of Environmental Sciences of Leiden University is looking for a PhD student on the topic of "development of nitrogen atmosphere - biosphere exchange models". This project is carried out in close cooperation with the Meteorology and Air Quality Group of Wageningen University. The project is part of the National Reactive Nitrogen Knowledge Programme (NKS). This programme aims to improve estimates of the deposition of nitrogen on nature areas in the Netherlands.
What will you be doing as a PhD student of atmosphere - biosphere exchange modelling?
The deposition of reactive nitrogen in Dutch nature areas is a societal problem that causes a great deal of concern. The reliability of the official deposition estimates is questioned by (some) politicians, economic stakeholders and part of the public. In order to strengthen the scientific basis of Dutch nitrogen policy, the Ministry of Agriculture, Nature and Food Quality (LNV) has set up a National Knowledge Programme (NKS) on the theme of reactive nitrogen. This NKS focuses on improving the measuring and modelling tools used in the Netherlands to map nitrogen deposition in nature areas.
You will make use of existing and new (inter)national surface exchange measurements to improve the quantification of the atmosphere - biosphere exchange of nitrogen components in dispersion models. In the first phase of the project, observations and numerical models of surface exchange are systematically compared for the nitrogen components: reduced and oxidised nitrogen and aerosols. This includes data analysis and further development of parameterisations of the surface exchange process. The second step focuses on further developing modelling of the atmosphere-biosphere exchange with all aspects involved, such as surface characteristics, weather conditions and vegetation characteristics. A substantial improvement of the deposition models makes it possible to estimate the nitrogen deposition on nature areas more accurately with dispersion models. The PhD student's activities thus contribute to an improvement of the current policy instruments.
You will work with atmosphere – biosphere exchange measurements and models to improve the current models that quantify the nitrogen deposition in the Netherlands. You will cooperate closely with the Meteorology and Air Quality group of Wageningen University and the other knowledge institutions within NKS (RIVM, TNO, KMNI). You are part of a team that will work on different aspects of quantifying the nitrogen cycle using satellite observations and dispersion modelling at different scales.
The position has a variety of tasks like:
The ideal candidate is a team player and has experience in statistical modelling and programming, affinity with mathematics, ecological knowledge with an interest in ecology. Specifically:
You will be part of an ambitious team of researchers studying atmospheric composition, emissions and deposition of air pollutants at both the Institute of Environmental Sciences and the Meteorology and Air Quality chair group at WUR. In addition, you will work closely with the other knowledge institutions within the NKS, in particular RIVM and TNO. You will participate in scientific discussions and actively contribute to scientific publications of the research team.
The position starts by 1st November 2022. We offer a position for four years. You will be appointed in accordance with the Collective Labour Agreement for Dutch Universities. Salary ranges from € 2.514.- gross per month in the first year to € 3.247 gross per month in the fourth year based on a full-time position.
Leiden University offers an attractive benefits package with additional holiday (8%) and end-of-year bonuses (8.3 %), training and career development. Our individual choices model gives you some freedom to assemble your own set of terms and conditions. For international spouses we have set up a dual career programme. Candidates from outside the Netherlands may be eligible for a substantial tax break. For more information, see the website.
