@fischer-ncar can I merge this before you start beta11 testing?

[fischer-ncar]

@jedwards4b Yes you can merge this. I'm only going to update the cmeps tag to include #329 for beta11 testing. I want the
testing to go as smooth as possible so I can start the holiday vacation.

[jedwards4b]

No we need to merge #327 as well and I think this one should be included too.

[fischer-ncar]

Okay, I'll include this pr and #327 in beta11 testing.
