Airborne particles play a critical role in environmental science with major implications for climate and air quality. Particulate matter (aerosols) is one of the most important factors for poor air quality and most of the estimated 4 million excess deaths per year stem from cardiovascular and respiratory diseases caused by particulate matter in the air. However, aerosols are highly complex and variable, especially in cities, due to their diverse sources (vehicle exhaust, industry, fuel-burning etc.) and atmospheric reactions and existing ground-based networks can give us only a very incomplete view on the urban aerosol distribution. For many cities, a new form of observation is required to provide aerosol air quality information to all and would transform our assessment of aerosol distributions and their likely health impacts.
Optical instruments on satellites are an important resource to monitor aerosols from space that can provide us with a wealth of details on aerosols not possible from ground-based observations. However, the spatial resolution of dedicated aerosol sensors is too coarse for cities. Consequently, many key questions on the urban aerosol distribution and their sources are unanswered, limiting our ability so far to make well-informed decisions for improving air quality within cities.
The recently launched Sentinel-2 can fundamentally change our approach to urban aerosols by allowing us to derive aerosol information on an unprecedented scale of tens of meters which is the relevant scale to pinpoint the different aerosol sources (roads, industrial facilities etc.), to diagnose aerosol variations across urban conurbations and to diagnose the impact of transport pathways within a city (street canyons).
In this project, we will make use of the power of the Sentinel-2 satellite to create a novel aerosol dataset with very high spatial resolution and use it to challenge our current understanding of urban aerosols. This studentship offers exciting science opportunities in the important and timely research area of urban air quality which is of large interest to the public and to policy makers. Results will be published in high quality journals and shared with government and local authorities, particularly through contacts in the Department for Environment, Food and Rural Affairs.
