Difficulties in Measuring Wet and Dry Deposition on Forest Canopies and Soil Surfaces
The identification of the important wet- and dry-deposition processes.
The determination of the nature of the effect, i.e. cumulative versus episodic, relative to the depositional process.
The quantitative measurement of the deposition rates of each process.
