New Mexico artist Andrea Polli stands in front of her digital-media installation 'Particle Falls' at the debut of the artwork in Downtown on Saturday, Nov. 15, 2014. Taking readings from the air monitor mounted on the building across the street , the piece provides a real-time visualization of air quality at the location, sending a cascade of blue lights cascading down the side of the Benedum Center, which appears to sparkle as fine particulate matter is detected in the air. Scientists at the Center for Atmospheric Particle Studies at Carnegie Mellon University will use the air quality data generated by the installation for research.

Taking readings from the air monitor mounted on the building across the street , the piece provides a real-time visualization of air quality at the location, sending a cascade of blue lights cascading down the side of the Benedum Center. The blue waterfall-like projection appears to sparkle as fine particulate matter is detected in the air, becoming more active as cars or busses pass by. Ranking in the worst 10 percent of U.S. cities for average annual particle pollution, Pittsburgh is the fourth city to host the installation. It is funded by The Heinz Endowments’ Breathe Project.

TribLIVE commenting policy

You are solely responsible for your comments and by using TribLive.com you agree to our Terms of Service.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.

While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.

We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.

We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
