San Diego has more cars and residents than ever before, yet the city's air has been clearing up.
County Supervisor Ron Roberts announced today that San Diego has now met the EPA's 1997 ozone standards.
Local air quality officials want residents to see that progress in the palms of their hands. That's why they're working with the state's Air Resources Board on a mobile website that delivers hourly air quality updates to Californians.
The site is accessible from smartphones and tablets, using GPS technology to connect with the state's nearest air pollution sensor. San Diego County's Air Pollution Control Officer Bob Kard says a color-coded system tells users how clear the air is in their region.
"It really is a warning scale to say 'green is good, yellow is be cautious,' and you get down into other colors where you do not want to exercise," Kard said.
The California Air Resources Board's mobile website can be found at mobile.arb.ca.gov/breathewell.
