PhD Position on Data Assimilation for Scenario Forecasting of Urban Heat – TU Delft – Delft

TU Delft

Job description

The Geoscience and Engineering department of TU Delft is looking for a PhD to work in the interdisciplinary project UrbanAIR.

With advanced weather models we can forecast atmospheric circulation at smaller and smaller scales. High-resolution simulations of the urban air flows form the basis of so-called digital twins that support decision making. Digital twins simulate different atmospheric scenarios in a changing climate and urban landscape. By quantifying the uncertainties in these projections, digital twins support the planning of climate adaptation and mitigation in cities. Where should we plant trees? Should we opt for high-rise buildings or keep the buildings low? What can we do to mitigate urban heat islands and keep the city cool?

To answer such questions, data assimilation systematically combines numerical models with data to explore different possibilities of what the true system could be like. Designing a data-assimilation method that can deal with the nonlinearity of the small-scale atmospheric circulation using a limited number of observations is not straightforward. Methods that can deal with the nonlinear dynamics of the urban atmosphere can be computationally demanding, and recent innovations suggest that efficiency can be improved.

To tackle this challenge, you will team up with UrbanAIR partners NORCE and TU Ilmenau to co-develop an improved data assimilation strategy for application in the urban atmosphere that can also be applied in other complex systems. You will explore recently developed methods and develop an enhanced data-assimilation approach that allows decision-makers to evaluate different scenarios against their decision criteria. The resulting approach will then be embedded into a digital twin of urban atmospheric circulation that will be co-designed with stakeholders in the cities of Barcelona, Antwerp, Rotterdam, Paris, and Bristol. In this multi- and transdisciplinary project, you will join the UrbanAIR project funded by the EU Horizon Europe funding programme. It involves five departments of TU Delft and 18 international partners across industry, academia and government.

As a PhD student at TU Delft, you will:

  • Familiarize yourself with nonlinear data-assimilation methods such as the , the , and the
  • Co-develop a scalable, adaptive, nonlinear data assimilation method based on recently developed methods
  • Explore innovative strategies to adapt the method to application for urban air circulation
  • Implement the resulting algorithm into a digital twin for application in selected cities in Europe.

 

This four-year project is part of a collaboration between TU Delft, TU Ilmenau, Germany, and NORCE in Bergen, Norway within the framework of the EU-funded project UrbainAIR. You will join TU Delft’s Department of Geoscience & Engineering, where you will find a vibrant and collaborative environment in which you will have the opportunity to interact with experts and fellow PhD candidates in data assimilation, atmospheric modelling, and numerical simulation. You will be encouraged to learn new skills and develop your own ideas, and you will share your findings at conferences and in peer-reviewed journals. These experiences will pave the way for diverse career paths in research institutes, governmental agencies, industry, (environmental) consultancy or academia.
