It was noted that there are observations where GSIHofX is zero. See plot below. This is only occuring where the observation value is set to missing, so appears to be a quirk in the GSI. I am still trying to track down exactly where the logic is that is doing this, but this should not adversely affect JEDI validation.
Here are a few more examples of zero HofX from GSI caused by missing observations: This is fixed by output GSI HofX instead of getting HofX from Obs-(Obs-HofX)

This issue will be used to track progress on the development and validation of radiances in UFO for GDAS in four stages:
1. Validation with GeoVaLs from GSI:
varinv
(outputvarinv
instead ofvarinv0
)2. UFO development:
HydrometeorCheckAMSUA
into three separate checks for clarity --- work in progress TheHydrometeorCheckAMSUA
will be separated into three single checks: RainCheck, CloudCheck, and SurfaceEmissivityCheck, and these checks will be filtered over land and ocean separately.3. IODA-converter development:
4. HofX computation in FV3-JEDI with GDASApp workflow:
