6. Line Sources

Try these first

1. 1.

   Define what a point source is in air pollution context.

   Hint

   Think of a factory or power plant.

2. 2.

   What does AERMOD stand for?

   Hint

   Remember it's a regulatory model?

3. 3.

   Which of the following is a primary feature of AERMOD?

   • Steady-state modeling
   • Non-steady-state modeling
   • Chemical reactions involved

   Hint

   Recall what AERMOD is primarily used for.

4. 4.

   True or False: CALPUFF can model instantaneous releases effectively.

   • True
   • False

   Hint

   Think about the different states CALPUFF can handle.

5. 5.

   Given a scenario where two factories release pollutants intermittently, propose a method to assess the cumulative air quality impact using AERMOD.

   Hint

   Think about how to overlap emissions and calculate effects.

6. 6.

   Analyze a case where an explosion causes an immediate release of chemicals—how would you use CALPUFF to model this situation?

   Hint

   Focus on the nature of the release and the required adjustments.
