DNA09-P-S.grid - the model file
The P- and S-vel models are provided on a regular grid.
Columns are: radius(km) lat(deg) lon(deg) DNA09-P(% Vp anomaly) DNA09-S(% Vs anomaly)
Model grid:
32 deg N to 49 deg N with 0.2 deg node spacing = 86 nodes
125 deg W to 104 deg W with 0.2 deg node spacing = 106 nodes
5370 km to 6370 km radius, ie 0 to 1000 km depth, with 25 km spacing = 41 nodes
Order:
grid starts at 5370.00 32.00 -125.00 ie bottom south west corner
first scans through longitude to bottom south east corner
then scans with increasing lattitude
then scans with increasing radius
last grid point is 6370.00 49.00 -104.00 ie the sop north east corner

3DVisualizer - visualization software provided by UC Davis KeckCaves (free)
This model file can be read the 3DVisualizer. A run script and color pallets are provided.
The 3DVisualizer software is available from: http://keckcaves.ucdavis.edu
It runs on a Mac or Linuz box, is easy to install and use.
