These files are individual maps and input data for dynamic topography
estimates from

Becker, T. W., Faccenna, C., Humphreys, E. D., Lowry, A. R., and
Miller, M. S.: Static and dynamic support of western
U.S. topography. Earth Planet. Sci. Lett., 402, 234-246, 2014.

Data is in the Netcdf/GMT format and can be converted to ASCII via GMT
grd2xyz file.grd | gzip -c > file.dat.gz
where file.dat would be lon-lat-value, and value dynamic topography in [km].
