looks good.

This. PR depends on two UFO PRs. One updates the GMI clouds index retrieval referring to algorithm used in GFS and the other one adds an optional input "absolute threshold vector" in the Background Check filter, which enables us to read the maximum observational errors from the observation_chronicle tables.

@jianjunj Is this PR still in active development? I am planning on merging jcb-gdas into the gdasapp repo, and I'm trying to figure out which jcb-gdas PRs can be merged quickly. If this PR cannot be merged quickly, it will have to become a gdasapp PR.

[jianjunj]

@DavidNew-NOAA Let me check whether these updates still stand.

[RussTreadon-NOAA]

@jianjunj : What is the status of this PR? We can not move forward with GDASApp PR #2031 until this PR is either (a) merged into jcb-gdas develop or (b) closed without action.

Tagging @DavidNew-NOAA and @CoryMartin-NOAA for awareness.

[jianjunj]

@DavidNew-NOAA @RussTreadon-NOAA Just let you know I am making some minor update right now. Will get back to you soon.

[RussTreadon-NOAA]

@jianjunj and @DavidNew-NOAA

This PR adds two new files

• observation_chronicle/atmosphere/gmi_gpm.yaml
• observations/atmosphere/gmi_gpm.yaml.j2

Given this, we could

1. close this PR
2. get GDASApp PR #2031 into GDASApp develop
3. open a GDASApp PR to merge the above gmi_gpm files into GDASApp parm/jcb-gdas.

What do you think?

[jianjunj]

@RussTreadon-NOAA @DavidNew-NOAA This PR can be merged now.

[RussTreadon-NOAA]

@jianjunj : Can you confirm that merger of this PR into jcb-gdas develop will not break anything in GDASApp develop? We can merge given your confirmation.

[DavidNew-NOAA]

@RussTreadon-NOAA This PR is just adding an observation which I'm assuming isn't turned on in any of our obs lists anywhere, since until this PR, no YAML has existed for that observation. I think we can be fairly confident that nothing will break.

[RussTreadon-NOAA]

I entirely agree, @DavidNew-NOAA. Just wanting to @jianjunj to chime in as the developer responsible for these changes.

Thank you for updating his branch with develop. Let's merge so you can keep moving forward.

[DavidNew-NOAA]

Will merge now. Thanks @jianjunj and @RussTreadon-NOAA

@RussellManser-NCO I didn't expect that since it didn't activate the assimilation of GMI data. Since I was wrong before, however, I am running these ctests now.
