  abstract = {{T}he knowledge of the local soil structure is important for the assessment of seismic hazards. {A} widespread, but time-consuming technique to retrieve the parameters of the local underground is the drilling of boreholes. {A}nother way to obtain the shear wave velocity profile at a given location is the inversion of surface wave dispersion curves. {T}o ensure a good resolution for both superficial and deeper layers, the used dispersion curves need to cover a wide frequency range. {T}his wide frequency range can be obtained using several arrays of seismic sensors or a single array comprising a large number of sensors. {C}onsequently, these measurements are time-consuming. {A} simpler alternative is provided by the use of the ellipticity of {R}ayleigh waves. {T}he frequency dependence of the ellipticity is tightly linked to the shear wave velocity profile. {F}urthermore, it can be measured using a single seismic sensor. {A}s soil structures obtained by scaling of a given model exhibit the same ellipticity curve, any inversion of the ellipticity curve alone will be ambiguous. {T}herefore, additional measurements which fix the absolute value of the shear wave velocity profile at some points have to be included in the inversion process. {S}mall-scale spatial autocorrelation measurements or {MASW} measurements can provide the needed data. {U}sing a theoretical soil structure, we show which parts of the ellipticity curve have to be included in the inversion process to get a reliable result and which parts can be omitted. {F}urthermore, the use of autocorrelation or high-frequency dispersion curves will be highlighted. {T}he resulting guidelines for inversions including ellipticity data are then applied to real data measurements collected at 14 different sites during the {E}uropean {NERIES} project. {I}t is found that the results are in good agreement with dispersion curve measurements. {F}urthermore, the method can help in identifying the mode of {R}ayleigh waves in dispersion curve measurements.},
