2.1. Application of Dispersion Models

Try these first

1. 1.

   Define dispersion models.

   Hint

   Think about their purpose in environmental monitoring.

2. 2.

   What is the difference between a point source and an area source?

   Hint

   Consider examples of each.

3. 3.

   What is the primary purpose of dispersion models?

   • To forecast weather
   • To simulate pollutant spread
   • To monitor global warming
   • To measure air pressure

   Hint

   Remember the context of pollution assessment.

4. 4.

   True or False: AERMOD is the same as CALPUFF.

   • True
   • False

   Hint

   Consider their definitions.

5. 5.

   A factory emits pollutants from multiple stacks. Describe how you would model their contributions and the challenges involved.

   Hint

   Consider what factors can complicate the additive nature of emissions.

6. 6.

   After releasing a tracer gas, field measurements indicated that the predicted concentration was significantly lower than actual observations. How would you adjust the model?

   Hint

   Think about what external factors might necessitate model adjustment.
