The SoundCity Project MONICA aims to provide a very large scale demonstration of multiple existing and new Internet of Things technologies for Smarter Living. The solution will be deployed in 6 major cities in Europe. MONICA demonstrates a large scale IoT ecosystem that uses innovative wearable and portable IoT sensors and actuators with closed-loop back-end services integrated into an interoperable, cloud-based platform capable of offering a multitude of simultaneous, targeted applications. All ecosystems will be demonstrated in the scope of large scale city events, but have general applicability for dynamically deploying Smart City applications in many fixed locations such as airports, main traffic arterials, and construction sites. Moreover, it is inherent in the MONICA approach to identify the official standardisation potential areas in all stages of the project. MONICA will demonstrate an IoT platform in massive scale operating conditions; capable of handling at least 10.000 simultaneous real end-users with wearable and portable sensors using existing and emerging technologies (TRL 5-6) and based upon open standards and architectures. It will design, develop and deploy a platform capable of integrating large amounts of heterogeneous, interoperable IoT enabled sensors with different data capabilities (video, audio, data), resource constraints (wearables, Smartphones, Smartwatches), bandwidth (UWB, M2M), costs (professional, consumer), and deployment (wearable, mobile, fixed, airborne) as well as actuators (lights, LED, cameras, alarms, drones, loudspeakers). It will demo end-to-end, closed loop solutions covering everything from devices and middleware with semantic annotations through a multitude of wireless communication channels to cloud based applications and back to actuation networks. Humans-in-the-Loop is demonstrated through integrating Situational Awareness and Decision Support tools for organisers, security staff and sound engineers situation rooms.

Each year, pollution claims thousands of lives across Europe, yet city administrations struggle with limited resources and the need to balance the multiple and uncertain effects of potential solutions. PUREPOLIS is set to transform urban health by pioneering advanced tools that empower policymakers to take high-impact action. At its core, PUREPOLIS drives data-driven, citizen-powered, and science-backed decision-making. A breakthrough Citizen Science Application (PR1) will enhance engagement and real-time monitoring. The Near Real-Time Pollution Source Apportionment tool (PR2) and Risk-based Health Impact Assessment framework coupling epidemiology and toxicology approaches (PR3) will precisely link exposure to 35 pollutants and their combination across air, noise, water, and soil to 10 critical health risks, including wellbeing. To maximize the efficiency of Zero Pollution Measures, PUREPOLIS will deploy cutting-edge analysis (PR6) to assess their effectiveness in terms of health, economic, and climate impacts, embracing a complexity perspective. These insights will feed into a Dynamic Abatement Strategies Toolbox (PR7), ensuring seamless policy integration into co-created, tailored comprehensive strategy for each of the two case studies in France and Spain, optimising co-benefits with multiple policy sectors. PUREPOLIS also pioneers a Vulnerability framework (PR4) and Behaviour framework (PR5) to drive behavioural changes for more successful interventions and foster equitable and sustainable solutions. Beyond core cities in France and Spain, a next-gen Digital Twin (PR8) and policy reports (PR9) will ensure replicability, scalability, and real-world impact across Europe. With nineteen partners from eight countries over thirty-six months, PUREPOLIS is an unprecedented step forward for healthier, more resilient cities. By fusing science, digital innovation, and citizen-driven action, PUREPOLIS sets a new gold standard for pollution mitigation in Europe.
