Global impacts of aircraft emissions on air quality and nitrogen deposition

Global passenger air traffic has doubled in the 13 years prior to 2019, and is expected to double again over the next 20 years or so. Growing demand for aviation is met by a corresponding increase in jet fuel being burned by aircraft, releasing multiple pollutants into the atmosphere. Besides disturbing the Earth’s radiative balance, these...

Multi-Source Data Modelling to Understand the Effects of Tourism Demand on Air Quality in Italy

The goal of this research is to model and understand the effects of tourism demand on air quality by performing data integration on multi-source data. This research is aimed at researchers and practitioners aiming to perform multidisciplinary research in the fields of data science and geoscience, presenting the methods and challenges that arise...

How IOT solutions can help policymakers monitor heat and air quality in urban areas as a part of their smart city strategy?

Cities are the centres of communication, commerce, and culture. Although, more than 80% of global GDP is generated in urban districts, the cities consume two-thirds of global resources and produce more than 70% of global CO2 emissions. Rising population, escalating urban pollution, the effects of climate change urge cities to search for...

An efficient ensemble Kalman Filter implementation via shrinkage covariance matrix estimation: exploiting prior knowledge

In this paper, we propose an efficient and practical implementation of the ensemble Kalman filter via shrinkage covariance matrix estimation. Our filter implementation combines information brought by an ensemble of model realizations, and that based on our prior knowledge about the dynamical system of interest. We perform the combination of...

COVID-19: Research Directions for Non-Clinical Aerosol-Generating Facilities in the Built Environment

Physical contact and respiratory droplet transmission have been widely regarded as the main routes of COVID-19 infection. However, mounting evidence has unveiled the risk of aerosol transmission of the virus. Whereas caution has been taken to avoid this risk in association with clinical facilities, facilities such as spa pools and Jacuzzis,...

Implications of future atmospheric composition in decision-making for sustainable aviation

Aviation emissions lead to degraded air quality and adverse human health impacts, making air quality one of the leading environmental externalities associated with aviation. Aviation emissions have been growing steadily over the past decades, and, despite the current hindrance in air traffic due to the COVID- 19 pandemic, they are forecasted to...

Design of a nature-based air purifier

This report showcases the design process of an air purifier that is based on the technology ‘active botanical biofiltration’, is designed specifically for a target group and it serves as an exploration of solar power applied to the mentioned technology. Indoor air contamination is a big problem for our urbanized societies, as it causes chronic...

Regional sensitivities of air quality and human health impacts to aviation emissions

Emissions from civil aviation degrade air quality, and have been estimated to lead to ~16 000 premature deaths annually. Previous studies have indicated that aviation emissions in different regions have varying corresponding air quality and human health impacts. Given the global nature of aviation activity and its forecasted regionally...
