	As an instrument measures the fluctuations of a variable such as velocity, shear, or temperature with a sensor at one location for a period of time the effect of eddies is observed as they drift by the sensor. However, the eddies could be changing size and shape as they drift by the sensor. Solviev and Lukas reduce the practical suitability of any situation to requirement that the fluctuations are within 10% of its mean speed past the sensor<ref>Soloviev, A. and Lukas, R., 2003.

			Taylor’s frozen turbulence hypothesis (sometimes "frozen field" or "frozen eddy")<ref>Taylor GI (1938) The spectrum of turbulence. Proc Roy Soc Lond 164: 476–490 https://doi.org/10.1098/rspa.1938.0032</ref> is a primary assumption invoked when seeking to quantify turbulence physics using time-resolving sensors<ref>Higgins, C.W., Froidevaux, M., Simeonov, V., Vercauteren, N., Barry, C. and Parlange, M.B., 2012. The effect of scale on the applicability of Taylor’s frozen turbulence hypothesis in the atmospheric boundary layer. Boundary-layer meteorology, 143(2), pp.379-391. https://doi.org/10.1007/s10546-012-9701-1</ref>. Thus it is applicable to the shear and velocimeter approaches described here.
