Description:

This is work from @MicroTed

This NSSL-MP update makes some improvements under the hood. No changes to the public subroutine calls.

• More accurate saturation mixing ratio calculation (iqvsopt=1)
• Changed default droplet renucleation to irenuc=5, which allows extra nucleation at high supersaturation
• A default explicit rain breakup for 3-moment rain (irainbreak=2) has been added to reduce excessive median drop diameters in rain cores, which in turn increases evaporation and cool pool temperature deficits (were too warm).
• Imposed reflectivity conservation in graupel->hail conversion (ihlcnh=3) and Bigg freezing (both 2- and 3-moment)

This PR also contains changes to the CCPP scientific documentation for the SRW v3 release. Output is here: https://dtcenter.ucar.edu/GMTB/UFS_SRW_App_v3.0.0/sci_doc/index.html

Combined PR: #2718

This PR updates stochastic physics to enable the running of standalone tests along with the automation of standalone tests via Jenkins pipeline integration.

UFS RTs running now on Hera. Will update logs when finished.

[grantfirl]

All tests that failed are expected except for test_cpld_control_pdlib_p8_gnu which timed out.

[jkbk2004]

@grantfirl it sounds like you are on leave. Anyway, we can schedule when you come back.

@jkbk2004 OK, this has been updated to the latest develop branches.

[jkbk2004]

@grantfirl can you point to NOAA-EMC/MOM6@25ed632? We can combine #2718. Just need to point to https://github.com/kbooker79/stochastic_physics/tree/platform-1077

#2718

Is there a UWM PR associated with the MOM6 commit hash change?

[jkbk2004]

@grantfirl Git issue only: #2717. I did sanity check ok to update the hash.

[BrianCurtis-NOAA]

Have we verified that test_cpld_control_pdlib_p8_gnu is passing or still timing out?

[grantfirl]

Have we verified that test_cpld_control_pdlib_p8_gnu is passing or still timing out?

The latest RT log from Hera showed no problems with cpld_control_pdlib_p8_gnu.

The latest RT log from Hera showed no problems with cpld_control_pdlib_p8_gnu.

The test_changes.list has that test listed, so the process would include regenerating baselines for that file. If it was just a timeout, and not due to baselines changing, then we would want to update the test_changes.list to make note that it's not timing out any more and it's not expected to change baselines. Looking back at this PR for any reason would make me think this PR caused changes to that test.

I just wanted to make sure that before starting testing the gnu test passed. Maybe I missed it?

I didn't re-run the pretest, but it definitely should not change the results for it. Would you like me to try to re-run the test to compare against the previous baseline?

I don't wish to add anything to your plate, I'll run that test to confirm it compared to previous baselines

@BrianCurtis-NOAA Thanks very much, I appreciate it.

[jkbk2004]

I re-test cpld_debug_pdlib_p8 against 0416 baseline on hercules and confirm no problem.
