x/y streaks in MPASSIT output #58

Open EricJames-NOAA opened 2 months ago

EricJames-NOAA commented 2 months ago

In carrying out some UPP testing, I found that the "U" and "V" 3D fields in mpassit output have nonphysical streaks along the x and y direction, respectively. You can see an example in this file on Jet:

/lfs5/BMC/wrfruc/ejames/rrfs2/stmp/conus12km/1.0.1/rrfs.20240527/03/mpassit/01/mpassit.2024-05-27_04.00.00.nc

I didn't find these artefacts in other fields, although I haven't confirmed if they exist in other cases.

It looks like we may be using a different version of MPASSIT than the HRRRv5 configuration. I confirmed the HRRRv5 MPASSIT output does not have this issue.

@EricJames-NOAA Thanks for the examination. The workflow does not compile the MPASSIT yet (it is a todo item as described in issue #25 )

Right now, MPASSIT copies everything from the HRRRv5 directory but stages them under a centralized FIX_RRFS2/ location. I guess there might be some parameters not setting correctly.
