Particle Falls

Although air is invisible, it has a major impact on public health. Santa Clara County received a failing grade for air quality in the American Lung Association’s 2009 State of the Air Report and currently surpasses unhealthy short-term pollution particles a yearly average of 11 days, the 24th highest level in the US. The number of people that airborne particulate pollution kills each year has tripled in California. Despite the invisibility of air, modern sensors can detect tiny particulate pollution levels in real time. Particulate pollution can be measured by laser light scattering, and Particle Falls provides a real time visualization of particulate pollution in the San Fernando Corridor using the latest projection technology. The project focuses on the smallest particle, PM2.5, since the global monitoring of it is one of the most recent developments in aeronomy.
