Prof. Alcherio Martinoli from EPFL will give a talk on Jan. 12th at 11:00 in Salle Minquiers.
High-Resolution Air Quality Sensing and Mapping in Urban Settings
In this talk, I will describe our efforts in the area of distributed sensing for air quality assessment in urban settings based on the achievements of two recent multi-PI collaborative projects (OpenSense and OpenSWISS), financially supported by the Swiss research initiative NanoTera.ch. Our research aims at providing high-resolution air quality maps through the integration of heterogeneous measurement sources in order to understand the health impacts of air pollution exposure. We target the development of end-to-end systems, ranging from the actual sensing and estimation of the field to the visualization of recommendations on the smartphone of the user, passing through a backend server system able to handle very large amount of data. In particular, our research leverages novel mobile sensing technologies that can provide air quality data with unprecedented temporal and spatial resolution, thus opening exciting new opportunities for the study of urban air quality and its impact on health.
Our work differentiates from other similar projects for its strong effort in ensuring data quality, in particular by leveraging on-line calibration methods, techniques for mitigating the impact of mobility effects, and thorough quantitative comparison of the data delivered by novel sensing technologies with those delivered by traditional high-end reference stations. In the context of OpenSense, we also provided innovative mapping techniques obtained with advanced physics-based modeling methods augmented by data provided by sparse reference stations or with a combination of dense measurements augmented by statistical, data-driven models.
While I will briefly describe all the different aspects of the project, I will specifically focus on the contribution of our laboratory (DISAL) for which mechatronics and robotics expertise was necessary.
