Functie­omschrijving

KNMI in De Bilt is looking for a PhD student using NO2 satellite data for the National Reactive Nitrogen Knowledge Programme (NKS) who will use satellite data to arrive at improved estimates of emissions, concentrations, and deposition of nitrogen in the Netherlands. Do you want to do a PhD at an exceptional institute where science, technology and services come together? Then make this vacancy your new job and apply immediately.

Your job as a PhD-student NO2
Excess deposition of reactive nitrogen species on nature areas is troubling the Netherlands since decades. The quality of the deposition estimates is questioned by politicians, economic stakeholders, and the general public. To improve the scientific basis of the Dutch nitrogen policy, the Ministry of Agriculture, Nature and Food Quality (Ministerie van Landbouw, Natuur en Voedselkwaliteit, LNV) has initiated a National Knowledge Program on Reactive Nitrogen (Nationaal Kennisprogramma Stikstof (NKS)). This NKS aims to improve the measurement and modelling system that is used to evaluate the nitrogen deposition on Dutch nature areas.

The PhD-student at KNMI will use satellite data, complementary to conventional ground-based measurements of reactive nitrogen and modelling tools, to improve the understanding of the distribution of nitrogen oxide (NOx) emissions. In the first phase of the project, the aim is to optimize the comparison between observed and modelled nitrogen dioxide concentrations. In the next step, the focus will be on developing inverse methods to estimate NOx emission estimates from TROPOMI nitrogen dioxide (NO2) observations. Such emission estimates allow to distinguish the ultimate nitrogen deposition caused by Dutch NOx emissions from the nitrogen deposition caused by agricultural ammonia emissions or foreign sources. The activities of the PhD-student should lead to new approaches that improve the Dutch policy instruments beyond what is currently available.

The PhD-student will be based in the R&D Satellite Observations department at KNMI and work together closely with the Meteorology and Air Quality group at Wageningen University, RIVM, TNO, and other (inter)national partners in the NKS.

The ministry of LNV has asked RIVM, WUR, KNMI, TNO and University of Leiden to elaborate the question on whether and how the use of satellite data and ensemble modelling may improve the determination of the nitrogen deposition in the Netherlands. Within the framework of the NKS, these partners have written a research program in which the use of satellite data and ensemble modelling is explored and elaborated. The central aim of the program is: to reduce the uncertainty of the calculated nitrogen deposition on nature areas in the Netherlands. To this end, PhD-students based at KNMI (NOx - this vacancy) and the University of Leiden (NH3), will strongly collaborate with the other partners.

How do we work?
Through the partnership with Wageningen University, you will join the SENSE Research School. SENSE provides multidisciplinary training modules, offers a network of other PhD students, and helps you to set up and implement a feasible PhD plan.

Meer over jouw toekomstige afdeling

The Research and Development Satellite Observations (RDSW) department of the KNMI (the Netherlands) contributes to weather and climate research and monitoring of the Earth system by using satellite measurements as well as surface remote sensing, balloon, and aircraft observations. Its main research objectives are climate research, air quality and stratospheric ozone. The satellite activities of the department encompass the entire range from collecting user requirements, developing instrument concepts, generating the required satellite products, to atmospheric research using the satellite data. KNMI is the Principal Investigator institute for the Sentinel-5P mission with the TROPOMI instrument and is responsible for the development of retrieval products including nitrogen dioxide (NO2).
More information on the department can be found at: https://www.knmi.nl/research/satellite-observations.

There is a positive attitude. Colleagues are friendly with each other, like to have a cup of coffee together and are very approachable. The mix of men and women of different ages and with diverse backgrounds also contributes to a pleasant working atmosphere within the department.

Royal Dutch Meteorological Institute (KNMI)

The weather is temperamental, the ground moves and the climate changes. For our safety and prosperity, we need to know what risks and opportunities this brings. And: how we can best prepare ourselves. The Royal Dutch Meteorological Institute (KNMI) is the national knowledge and data center for weather, climate and seismology. Reliable, independent and focused on what the Netherlands needs. For a safe Netherlands that is prepared for the impact of weather, climate and earthquakes.

We use our core values - Development, Cooperation and Relevance - to achieve our ambition, both within and outside KNMI, nationally and internationally. We develop our knowledge and expertise and work together to create a single KNMI that makes a difference to society!

Talent as the basis, diversity as the strength
The KNMI is an inclusive organization. An organization that provides space for everyone and uses the strength of its diverse workforce to achieve better results together for the Netherlands. Inclusive means that everyone feels involved and valued; not in spite of their differences, but thanks to them.

Organisationally, KNMI falls under the Ministry of Infrastructure and Water Management.
The Ministry of Infrastructure and Water Management (IenW) is committed to a safe, accessible and liveable Netherlands. That is why the Ministry is working on powerful connections by road, rail, water and air. And IenW protects against flooding, ensures the quality of air, water and soil and the realization of a circular economy.
