The role of urban trees in mitigating air temperature and pollution in cities (M.Sc. Topic)

Diverse illustrations of an urban lanscape with trees — Representation of land use as well as RGB and 3D data of urban areas.

Background: Urban areas are facing increasing challenges associated with rising temperatures and air pollution, exacerbated by the effects of climate change and urbanization. In this context, the role of urban trees in mitigating these challenges has garnered significant attention from researchers, and urban planners. Trees in urban environments have been recognized for their potential to reduce temperatures and improve air quality through shading, transpiration, and the removal of air pollutants. Yet, it is essential to recognize that they can also pose challenges e.g. for air circulation.
Despite these recognized benefits and challenges, there is still no consensus on the effectiveness of urban trees and tree species in reducing temperature and air pollution.

Aim: Here, we aim to conduct a comprehensive assessment of the role of urban trees in reducing air temperatures and improving air quality in Zurich.

Methods: We will collect and analyze spatially and temporally extensive microclimate, pollution, and comprehensive tree canopy structure data. Remote sensing data coming from airborne laser scanning (ALS) or other sources will be processed. The field measurement will happen in the summer and mobile sensors will be used for the measurements. Analysis: GIS and statistical analyses will be used to assess the microclimate relationship with tree traits and the statistical significance of potential trends.

Wanted: Highly motivated student interested in modelling who is willing to learn about trees in urban environments.
The project has a flexible starting date.

You will get to:

Learn how and why urban environments are influenced by tree species and, more importantly, practical knowledge about the use of specific sensors, and gain important statistical skills for your future work.
Expand your network by discussing your work with experts from the intersecting fields of forest sciences and urban science.
Be a co-author on a publication resulting from this work.
Be part of a motivated, fun, and energetic team of scientists.

Supervisor: Dr. M. Beloiu Schwenke, Dr. Martin Mokros (Lecturer in Earth Observation at University College London)

The project aims to start preferably as soon as possible.
