  • CONSTRAINTS ON UPPER INNER-CORE STRUCTURE FROM WAVEFORM INVERSION OF CORE PHASES 
    Garcia R. (2002)
    The determination of the inner-core boundary structure is key to understanding the mechanisms of inner-core growth, iron solidification and anisotropy formation in the inner core. A waveform inversion of a worldwide data ...
  • GLOBAL P AND PP TRAVELTIME TOMOGRAPHY: RAYS VERSUS WAVES 
    Montelli R.; Nolet G.; Masters G.; Dahlen F.A.; Hung S.H. (2004)
    This paper presents a comparison of ray-theoretical and finite-frequency traveltime tomography for compressional waves. Our data set consists of 86 405 long-period P and PP-P traveltimes measured by cross-correlation. The ...
