Nonpara_GIT_NZ_v1

To gain new insights into ground-motion phenomena in New Zealand (NZ), we apply the non-parametric generalized inversion technique (GIT) in the Fourier domain to isolate the systematic source, path, and site effects from 20,813 seismograms, recorded by 693 sensors at 439 unique locations, from 1200 shallow crustal events (Mw &gt; 3) during the period 2000-2021. The online resource provides the inverted source and site spectra and/or parameters, including:<b>Files/Folders:</b>“<i>Source_parameters.xlsx</i>” contains source parameters for each event.“<i>DataSet_Source</i>” includes plots of inverted and theoretical source spectra for each event.“<i>Amp_mean_uncertainty.xlsx</i>” contains inverted site-response functions (mean with uncertainty estimated via bootstraping, and site metadata) at each of the 319 strong-motion stations (HN &amp; BN) used in “Site Response” section.“<i>DataSet_Amp</i>” provides plots of site-response curves at each site, and its corresponding azimuth coverage.Reference:<i>Zhu, C., S.
