Multiple choice

Which of the following is NOT a common type of air quality model?

  1. Dispersion models

  2. Chemical transport models

  3. Source-receptor models

  4. Statistical models
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Statistical models are not typically used for air quality modeling as they do not explicitly simulate the physical and chemical processes that govern air pollution.

Multiple choice
