Challenge Problems
Push your limits with advanced challenges
A monitoring station needs to communicate the effectiveness of a new PM measurement technique compared to an existing one. Describe a strategy that could involve all three measurement methods.
💡 Hint: Consider how each method could complement the other's data.
Given the differences in measurement techniques, design an experimental study to evaluate the PM concentrations in an urban area using at least two different methods.
💡 Hint: Think about how you could set up the study to maximize data collection efficiency.
