I have been able to successfully run a test run of the hofx using the NBAM GNSSRO operator. Next I tried running the same experiment again using the MetOffice GNSSRO operator. It failed with errors I do not understand.

Here is my yaml input file:

And here is what I think is the most relevant part of the error message:

Hi @stephenh could you or someone you know who is familiar with this operator please take a look at my runtime problem when you get a chance.

Thanks,

Hi @mjm, sorry about the lack of response. I’ve forwarded this issue to the JEDI core team in our Slack messaging. Hopefully, someone will pick it up soon.

Two possible issues while using FV3 and UKMet RO operator:

State/control variables are different for FV3 and the operator

Vertical levels: UKMet models are staggering (uv are not at the same levels as for T and humidity) in a vertical direction but FV3 doesn’t.

It would be good to check these two parts first.

Hi @mjm is this problem resolved?

I have run the UK metoffice operator using the same yaml as yours except that I have a different date and JEDI version.  
The version I am using is a little bit different from yours in the geometry section. please see  
[https://github.com/JCSDA-internal/fv3-jedi/blob/develop/test/testinput/hofx\_nomodel.yaml](https://github.com/JCSDA-internal/fv3-jedi/blob/develop/test/testinput/hofx_nomodel.yaml)

While I have the same configuration in the entire “observations” section, I run through the operator successfully. Sorry that I can not reproduce your error. If you want more discussion please feel free to send direct email to me at hailingz@ucar.edu and I may use your data for further debugging.
