Summary
NA04, van der Lee and Frederiksen (2005) , is derived from inversion of the fundamental and higher mode Rayleigh waveforms using the Partitioned Waveform Inversion technique, Nolet (1990). The data set used includes waveforms from about 1400 regional seismograms recorded at North American digital broadband seismic stations (including the USArray Transportable Array waveforms). The NA04 3-D model is expressed as the velocity difference in m/s relative to the 1-D averaged Earth model MC35 .
