Liverpool’s air quality, much like many other UK’s cities, is some of the worst in Europe. Whilst we might understand how it is produced, complex urban layouts and meteorological conditions make it almost impossible to understand how it mixes, disperses and stagnates in our cities; the only way in which we can monitor this is to sense our cities. This research-based module focuses on students using statistical tools to interpret data from University of Liverpool outdoor pollution sensors, Liverpool City Council outdoor sensors, and Government sensors, as well your own sensor that students construct as part of this module. The module content will be provided in the first three weeks after which students will work on research-based projects, with intensive supervision. The module’s assessment gives students a taste of both the industry driven and academic world trhough a consultancy style group report and mimicking the process of presenting a paper at an acacemic conference.
