2. Gradient Technique and Micrometeorological Technique

Try these first

1. 1.

   What is flux in environmental terms?

   Hint

   Think about flow rates.

2. 2.

   Define the gradient technique.

   Hint

   It involves comparing concentrations.

3. 3.

   What does the gradient technique help determine?

   • Soil pH
   • Flux measurements
   • Temperature variations

   Hint

   Think about its purpose in environmental studies.

4. 4.

   True or False: The Thornwaite-Holzman equation considers both concentration and turbulent diffusion.

   • True
   • False

   Hint

   Consider what the equation represents.

5. 5.

   Calculate the flux if the concentration of a pollutant at height 1 is 600 µg/m³ and at height 2 is 400 µg/m³ over 10 meters with a diffusion coefficient of 2 m²/s.

   Hint

   Use the gradient formula to solve.

6. 6.

   Explain how non-instantaneous concentration measurements could lead to errors in estimating flux.

   Hint

   Reflect on temporal changes in pollutant levels.
