I suggest we put them in fix/gdas/ims or something like that.

[jiaruidong2017]

@CoryMartin-NOAA do you think which is better: either fix/gdas/obs/ims or fix/gdas/ims?

[CoryMartin-NOAA]

good question, I like your suggestion of adding obs

[KateFriedman-NOAA]

@CoryMartin-NOAA @jiaruidong2017 We're talking about a new timestamped fix subfolder (everything under fix/gdas/ has it's own versioning). Based on the comments above it looks like you want the following new fix subfolder for the new files: ../fix/gdas/obs/YYYYMMDD/ims and we'll then need a new version variable in versions/fix.ver for this new subset (e.g. gdas_obs_ver). Is that correct and/or sound good? Are you anticipating additional subfolders at the same level as ims?

I'll make the YYYYMMDD timestamp the date I create the folder and pull the files in...if that works for you guys. Let me know and I'll pull the files in. Thanks!

[CoryMartin-NOAA]

Works for me, @KateFriedman-NOAA thanks! and yes I think we envision some other mapping files for other observation types (such as VIIRS land products) in the future (not in this immediate version)

[KateFriedman-NOAA]

@CoryMartin-NOAA Sounds good!

I have created the discussed new subfolder structure and copied the files into it. Please see here on Hera:

Please confirm it looks good and we'll sync it to the other platform fix sets.

We now need to add export gdas_obs_ver=20240213 to versions/fix.ver. Do you have a branch you're planning to send that update in? If not, we'll want to submit a separate PR to add it.

[CoryMartin-NOAA]

Is it okay if that is included in the PR that will include changes to workflow scripts to grab these files from that location? Or would you prefer separate PRs?

[KateFriedman-NOAA]

Absolutely! Including in such a PR would be perfect. Make sure to have that PR close this issue too. Thanks!

[jiaruidong2017]

Thanks @KateFriedman-NOAA for your efforts.

[KateFriedman-NOAA]

FYI, the new files have now been synced to both WCOSS2s and Jet. Orion/Hercules will be synced shortly.

[CoryMartin-NOAA]

Thanks Kate, I'm working on the PR I mentioned today.
