Over the past decade, fine soot pollution known as PM2.5 has become a major environmental health worry, sparking new federal regulations and a flurry of research on how these tiny particles can aggravate respiratory diseases and even kill. To help the public and researchers get a handle on this problem, Hazecam.net monitors real-time haze—part of which is made up of fine particles—at sites across the Northeastern United States.

Sponsored by eight state air-quality control divisions, the site's Web cams offer 15-minute snapshots of visibility at six urban and rural locations including Boston, New York City, and Mount Washington in New Hampshire. You can also get a historical perspective by perusing a gallery of good and bad air days, such as this murky shot of Boston from 8 March of this year. For each locale, Hazecam also displays real-time measurements of fine particles, ozone, and other pollutants.
