Data Scientist

About This Position

Climate change, air quality, and the energy transition play a huge role in defining, implementing, and monitoring policy. To properly design and implement policies, it is crucial to understand emissions and concentrations of gases and substances, at both regional and national level and ideally in real-time. At the Environmental Modelling, Sensing & Analysis (EMSA) department, we use measurement equipment and sensor networks to monitor the concentrations of various gases and particles in the air. As a Data Scientist, you support the researchers within EMSA by managing, processing, and analyzing measurement data. You ensure that data is accurate, accessible, and available for both internal and external use.

What will be your role?

Researchers at EMSA measure and monitor concentrations of different gases and particles in the air in various locations and regions across the Netherlands. We do this using fixed and mobile measurement systems and state-of-the-art equipment. Examples include nitrogen compounds, greenhouse gases, and particulate matter characterisation. The data are centrally collected and stored following FAIR principles. These data serve as input for calculations related to models, emission factors, and policy.

Your mission is to help professionalize our data landscape and enable our scientists to work in an increasingly data-driven way. In addition, we are looking for someone who can, over time, help maintain, improve, and expand our existing IT systems.

Your responsibilities include

• Making data from the cloud available to analysts.
• Supporting analysts in the analysis, visualization, and interpretation of data.
• Maintaining and extending data acquisition software to read and control measurement instruments.
