Continental Breakfast, AM & PM Break in Expo Lunch on own in hotel outlets

Slido code 2081622 Sensor evaluation programs have been an important catalyst to the adoption of air quality sensor technology and to the improvements in reliability, comparability, and fitting for real-world use. The Air Quality Sensor Performance Evaluation Program (AQ-SPEC) at South Coast Air Quality Management District and the Afri-SET program in West Africa are two such sensor evaluation programs. This plenary will provide insights learned from over twelve years of sensors evaluations and the transition of these programs from exploratory efforts into comprehensive sensor evaluation centers. This plenary will cover early motivations and history, scientific and logistical challenges encountered, and the major accomplishments over the evolution of the evaluation programs. Drawing on extensive field and laboratory sensor evaluation efforts, the session will synthesize what has been learned about the current state of particle and gas sensor performance from both the AQ-SPEC and Afri-SET evaluation programs. A hypothetical comparison of evaluation results against several performance standards will also be discussed in this plenary. The plenary will discuss the growing need to evaluate non-criteria pollutants sensors and provide a look ahead at future capacity and opportunities for evaluation centers.

The Future of Air Quality Data: Who’s Accountable When It Matters Most? Air quality data has never been more accessible. Sensors are everywhere, and real-time readings are already driving alerts, forecasts, and recommendations that people, nonprofits, and governments act on. Data is shaping policy decisions and health initiatives — and its reach is expanding rapidly into AI tools, property valuations, insurance models, and beyond. As data travels farther and faster than ever, critical questions emerge: Who is verifying accuracy? What's at stake when the data is wrong? Who’s responsible? This session is a candid conversation about what accountability looks like as monitoring networks scale and the stakes get higher. Attendees will explore these questions in small group discussions, followed by a practitioner panel sharing insights and concrete actions to help ensure air quality data is handled with the care communities deserve. Lunch is provided. Pre-registration required**
