Air Pollution Questions

Multiple choice

What are the two main types of air pollution models?

  1. Deterministic and stochastic

  2. Eulerian and Lagrangian

  3. Gaussian and non-Gaussian

  4. Linear and nonlinear
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Eulerian models divide the atmosphere into a grid of cells and calculate the concentration of pollutants in each cell over time. Lagrangian models track the movement of individual air parcels and calculate the concentration of pollutants in each parcel over time.

Multiple choice

  1. Meteorological data

  2. Emissions data

  3. Air quality data

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Air pollution models require data on the weather, the emissions of pollutants into the atmosphere, and the current air quality in order to make accurate predictions.

Multiple choice
