Okay, well, I don't know if this phenomenon has a name...maybe call it the
"send and spot" troubleshooting solution, but literally 10 seconds after I
sent the email I discovered that I had given the config file the wrong
array name (APCP_A06, when it should be APCP_06).

DOI! Sorry to bother. You may disregard this help ticket.

Subject: Re: Error with MODE: cannot read from netcdf file

Jeff,

Thanks for letting us know you figured it out.

FYI, in the next couple of months, we plan to transition
met_help at ucar.edu over to GitHub Discussions at:
   https://github.com/dtcenter/METplus/discussions

We'll be sending out info about this transition soon. But I wanted to
give you a heads up.

Thanks,
John Halley Gotway
