Air monitoring is a critical part of air quality management, plays a vital role in understanding the complex nature of air pollution formation and providing information to develop effective control strategies. New monitoring technology is needed to support new air quality challenges. Low-cost sensor technologies provide more cost-effective ways to monitor air quality and help the public learn more about air quality in their communities. This webinar will discuss advances in air sensing technologies, particularly in air sensor data quality and applications of this new technology. It will also provide perspective on air sensors potential for regulatory applications and the performance of air sensors.
