Dear David:
 
Today I am finally able to provide you with the model of California velocities
and (2-D, surface) strain-rates for interseismic periods,
as you requested.
 
If you will navigate to this URL:
http://peterbird.name/oldFTP/temporary/for_David/
you will see a set of files prepared for you.
The most important is probably the 64-MB file,
interseismic_table.txt   .
 
I also provide the other 2 parts of the equation:
(longTermAverage) = (interseismic) + (meanCoseismic)
which can refer either to the velocity vector field or to the strain-rate
tensor field.
 
The grid resolution is 0.01 x 0.01 degrees.
Inland grid limits are 31N, 41N, and -114E.
The western limit is either -125E, or the limit of the region modeled,
whichever comes first.  (However, as the western limit is always offshore,
it will not hinder your comparison to the SCEC Community Geodetic Model.)
 
Please also take a look at the set of 12 colored maps in JPG format for an
overview of what is contained in the 3 table files.
 
I believe that this model is better in both quality and resolution than the one
I sent to you about 5 years ago for the your previous comparison study.
 
The primary basis for this model is the NeoKinema model NSHM-WUS_2013001,
which I prepared for use in both UCEF3 and the NSHM-WUS 2014 update.
All input and output files (and source code) for this model are online at:

The actual production of the 3 tables I am sending you was by a new utility program,
StrainRates2015.  It contains many subroutines and methods already developed and
used in NeoKinema; the main difference is the high resolution of its output files.
 
Best wishes,
