Particle Falls is a public artwork that provides a real time visualization of particulate pollution in the San Fernando Corridor in the form of a large-scale projection on the side of the AT&T Building in San Jose California and on mobile devices.
Particle Falls a night time projection, allows viewers to see current levels of fine particulates cascading down the facade of the AT&T building in San Jose using the large-scale projection technology. The project includes a nephelometer, which measures the smallest particle, PM2.5. The global monitoring of this particle is one of the most recent developments in aeronomy. Fewer bright particles over the waterfall mean fewer particles in the air.
A large-scale public art installation acts as a monitor, an alarm and a thing of beauty all at the same time by using particulate air pollution as a basis for a cascading waterfall flowing down the side of a building.
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.
Signage on site and particlefalls.org have been designed as companions to the public work. The signage provides information about local particulate pollution levels and their effects. A simple particulate pollution visualization designed for android mobile devices at particlefalls.org provides real time animation of current levels at the site. The number of ‘drops’ landing on the mobile screen is linked to current particulate levels, as if drops from the waterfall are landing on the viewer’s hand. Particlefalls.org also provides links to air quality monitoring information from the local Bay Area Air Quality Management District and the national AirNOW program.
