Challenge Problems
Push your limits with challenges.
Question 1
A scientist measures water vapor concentrations at two heights, finding 2 mg/m³ at 1m and 5 mg/m³ at 4m. Using the gradient technique, calculate the expected flux if the diffusion coefficient is 0.5 m²/s.
💡 Hint: Ensure to apply the correct heights and concentration values.
Question 2
Discuss the variation in flux measurements taken at different times of the day. How might temperature and wind influence your readings?
💡 Hint: Consider how environmental changes impact measurement conditions.
