On Scale of 0 to 500, Beijing’s Air Quality Tops ‘Crazy Bad’ at 755

From The New York Times:

“BEIJING — One Friday more than two years ago, an air-quality monitoring device atop the United States Embassy in Beijing recorded data so horrifying that someone in the embassy called the level of pollution “Crazy Bad” in an infamous Twitter post. That day the Air Quality Index, which uses standards set by the United States Environmental Protection Agency, had crept above 500, which was supposed to be the top of the scale.

So what phrase is appropriate to describe Saturday’s jaw-dropping reading of 755 at 8 p.m., when all of Beijing looked like an airport smokers’ lounge? Though an embassy spokesman said he did not immediately have comparative data, Beijing residents who follow the Twitter feed said the Saturday numbers appeared to be the highest recorded since the embassy began its monitoring system in 2008.”

Street Sensing: seeing tiny particles

If you’re in San Francisco, check out SPWS weather interpreter Tim Dye’s new project ‘Street Sensing: seeing tiny particles’, on Saturday, October 20 as part of a tech-art event in San Francisco at the Urban Prototyping exhibition.
‘Street Sensing: seeing tiny particles’ will use AirCasting to crowd source air quality measurements collected by citizens.  Attendees will have a chance to check out an AirCasting Air Monitor, LED Vest, and Android phone and troll the streets of downtown SF sensing tiny particles.
