The Department of Health is conducting a New York City Community Air Survey (NYCCAS) together with CUNY/Queens College. The survey is conducted from 150 street-level sites all over New York City, and initial reports are planned to be released at the end of 2009. NYCCAS will, however, not look at individual neighborhoods, but at air quality in NYC as a whole. The air pollution measurements will be analyzed using a statistical procedure known as ‘land use regression’ which examines how pollution levels vary in relation to traffic, buildings, trees, and other neighborhood factors.
