		:summary = "BBNAP19 is an adaptively parameterized, global absolute P-wave tomographic model following the methodologies of Li et al., (2008) and Burdick et al., (2017). ak135 (Kennett et al., 1995) is used as the global reference model. New data has been added in eastern U.S. and Canada, so we provide only the North American component of the model. While the adaptively parameterized grids at upper mantle depths are shown in the supplementary material of published manuscript, here we provide the model sampled at 0.25x0.25 degrees and 50km depth to facilitate smooth plotting. The 3D grid contains the columns: depth (km), latitude (deg), longitude (deg), dVp (percentage relative to ak135), vp (absolute vp in km/s)." ;
