There are two groups of methods used to measure dry deposition flux: surface analysis methods and atmospheric flux methods. The former group includes methods which analyze material accumulated on a surface. These methods include foliar extraction, throughfall and stemflow methods, use of surrogate surfaces, and snow sampling. The surface analysis methods provide a direct measurement of the amount of material delivered to a surface.
The atmospheric flux methods can be used to determine dry deposition from measurements of airborne concentrations and micrometeorological data. These methods include eddy correlation, the profile method, the tracer method, aerometric balance studies, eddy accumulation, and variance methods.
Details of the dry deposition measurement methods are available from various literature sources. The information from these sources was synthesized by M. J. Zufall and C. I. Davidson.
