Good Morning,

See below for the output from q config.  I will give PyGrADS a try and let
you know.

The end use of this data is going to be in allowing a colleague to
interpolate to ~4k locations around the globe so the thought was to put the
data into a format where our interpolation scripts could deal with it.  I am
sure there are much easier ways to do this but all of our attempts to try
this other ways have not been successful but if people have other
suggestions we are certainly open to hearing about them.  Thanks for all of
your help.

Hmm. I tried your script on my Mac OS X with v1.9.0-rc1 and it worked just
