Challenge Problems
Push your limits with advanced challenges
A factory has multiple stacks emitting pollutants at different rates. Consider that the contributions can be calculated but will not yield precise predictions due to interactions. Develop a hypothetical scenario to describe how emissions might interact and affect air quality over a given area.
💡 Hint: Think about how weather can influence dispersion.
Create a set of observations that would justify switching from a point source model to an area source model, using data from air quality samples taken near a landfill.
💡 Hint: Consider the geographic spread of emissions.
