To answer each question adjust the one of the controls available, take note of the effect, then restore the settings to default before moving to the next question. Weather Factors 1. Does increased or decreased cloud cover reduce the effects of low level ozone and result in a better AQI? Why is this? 2. What is temperature inversion? Which setting reduced low level ozone best and why? 3. What happened to the low level ozone readings as you increased the wind in smog city? Why is that? Is wind also potentially a problem? Explain. 4. Raising the temperature in smog city resulted in poorer AQI scores why? 5. Lowering temperatures also had a negative effect on the AQI, why? Emissions 1. Watch the landscape of smog city as you alter the energy sources scale. Although the AQI does not move much as you do this if you moved it to the far left can you think of another scale you could change that would create a positive combined effect? 2. Reducing vehicles off road and on lowers the AQI and the low level ozone. Why? Population 1. Why does an increase in population affect the low level ozone? Ideal Conditions An ideal AQI of 20 can be reached with these settings 1. Why are these ideal setting not always possible? AQI CLOUD: 3 INVERSION: 1 WIND: 4 TEMPERATURE: 4 ALL EMISSIONS & POPULATION 1 20 3 1 4 4 1 2. Which scales could you adjust in your own life/town that would be practical and still lower your AQI?
