Smog City

Smog City is an interactive air pollution simulator that shows how our activities and environmental conditions contribute to air pollution. See how ground-level ozone, a major ingredient of summertime smog, increases or decreases when you vary the

• weather conditions:
  • temperature
  • amount of cloud cover
  • wind speed
  • temperature inversion
• pollutant emissions from different categories:
  • cars and trucks
  • off-road vehicles like airplanes, trains and boats
  • factories
  • consumer products
• and population level.

You can set the weather factors to encourage ozone formation, and then try different ways of reducing emissions to keep ozone levels from becoming unhealthy. Find out how much the different emissions categories contribute to ozone levels.

Smog City was developed for the Sacramento Metropolitan Air Quality Management District, California using that area's weather, emissions and air quality data, so it may not simulate ozone formation in New Jersey exactly. But the concepts apply wherever ground-level ozone reaches unhealthy levels.
