We incorporate crustal thickness perturbations as model parameters in the inversions to properly consider crustal effects and suppress the leakage of crustal structure into mantle structure. This is possible since we utilize short\u2010period group\u2010velocity data with a period range down to 16\u2009s, which are strongly sensitive to the crust. The isotropic <jats:italic>S<\/jats:italic> velocity model shares common features with previous global <jats:italic>S<\/jats:italic> velocity models and shows excellent consistency with several high\u2010resolution upper mantle models. Our anisotropic model also agrees well with previous regional studies. Anomalous features in our anisotropic model are faster <jats:italic>SV<\/jats:italic> velocity anomalies along subduction zones at transition zone depths and faster <jats:italic>SH<\/jats:italic> velocity beneath slabs in the lower mantle. The derived crustal thickness perturbations also bring potentially important information about the crustal thickness beneath oceanic crusts, which has been difficult to constrain due to poor access compared with continental crusts.<\/jats:p>","DOI":"10.1002\/2014jb011824","type":"journal-article","created":{"date-parts":[[2015,5,15]],"date-time":"2015-05-15T15:34:04Z","timestamp":1431704044000},"page":"4278-4300","source":"Crossref","is-referenced-by-count":178,"title":["Joint inversion for global isotropic and radially anisotropic mantle structure including crustal thickness perturbations"],"prefix":"10.1029","volume":"120","author":[{"given":"Sung\u2010Joon","family":"Chang","sequence":"first","affiliation":[{"name":"School of Environmental Sciences University of East Anglia  Norwich UK"},{"name":"Now at Division of Geology and Geophysics Kangwon National University  Chuncheon South Korea"}]},{"given":"Ana M.
