Smog City Modeling
-> Which man-made contributing factor has the most influence over ground level ozone production?

In this activity, you will create an experiment and use the Smog City simulator to run the experiment. You will need a computer with internet access and a copy of the Student Worksheet.


  1. Access the Smog City web site (
  2. Click "Run Smog City” from the left-side navigation bar.
    • NOTE: Smog City is a JAVA Applet that runs in your Microsoft Internet Explorer or Netscape Navigator browser. For offline use, follow the Download link for instructions on downloading Smog City to your computer.
  3. Once Smog City loads to your computer, take note of the following areas of Smog City, including Weather Condition, Population Level, and Emissions Levels. All areas have “clickable” choices. Mouse-over or click on the choices.
    • NOTE: in the status bar at the bottom of the your browser, there is information about each choice when the mouse is hovering over one of the settings.
  4. Click the Red “Reset” button.
  5. Look at all the choices again. Notice how each of the choices are pre-set to a certain level. These are called the default settings. In the chart on your student worksheet (see example below), circle or highlight the default setting for each choice. The first setting, Maximum Daily Temperature, has already been completed for you.
