Spare the Air

The Bay Area Quality Management District set up the Spare the Air Program to spread awareness about the health effects of pollution and to encourage people to learn more about pollution prevention. You can learn more and sign-up to receive either e-mail or Automated Phone Alert notifications about Spare the Air days and air quality alerts by visiting the Spare the Air website.

iSmog iPhone App

iSmog displays air quality information for the San Francisco Bay Area on your iPhone, iPod or iPad. With just a tap on the screen, see an easy-to-understand map of environmental quality in the Bay Area’s five air basins built using data provided by the Bay Area Air Quality Management District (BAAQMD).

Use iSmog to monitor air quality conditions, be notified when poor air quality is forecast, and make more informed choices about environmentally friendly transportation options.
