@hongli-wang , is this the issue associated with PR #482?

[CoryMartin-NOAA]

@RussTreadon-NOAA I believe it is, but before closing we should wait for confirmation from @hongli-wang

[hongli-wang]

@RussTreadon-NOAA Yes, it is associated with PR #482. Thanks.

[RussTreadon-NOAA]

@hongli-wang , thank you for the confirmation.

Future development requires a more detailed issue. The issue should be opened at the start of development and document all your commits. Once development is ready to be considered for merger into develop, a PR can be opened. The PR should reference the issue. Merging and closing the PR will then automatically close the issue.

I will manually close this issue.
