@grantfirl Does more need to be done before this PR will be reviewed/merged? Still trying to understand the process with the production release branch. Thanks! |
|
@MatthewPyle-NOAA We just need to review it and @haiqinli needs to upload the test_changes.list file in ufs-community/ufs-weather-model#2147, assuming that we don't request changes. I'm also working on getting #147 and #159 in |

Thanks for the explanation, @grantfirl |

These are only whitespace changes. Is that intended? If not, please revert this change.

Why are you adding totprcp when you're not using it?

@grantfirl I will remove this unused variable. Thanks.

Same question. Please remove this change if you're not using totprcp.

@haiqinli Looks fine with the exception of some minor typo-like things. Once you address those, I'll approve. Please remember to commit the test_changes.list file that is generated now in the ufs-weather-model/tests directory for that PR. |

@haiqinli @mdtoyNOAA Will this change affect global and HAFS applications as well ? Have any tests been done to check the impact on applicaitons other than RRFS ?

We tested this change in the HR3 C768 FV3GFS and detected improvements to the 500hPa ACC scores.

Mike, that is good know. I'd assume this has major impact on surface winds and turbulent exchange coefficients as well. Did you also see positive impact on grid-to-obs stats ?

Mike, since this change is hardwired and will be include in HR4. Please record this change in our tracking spreadsheet.

@yangfanglin Keep in mind that this PR is just targeting the RRFS.v1 branch.

@MatthewPyle-NOAA I see. So the change is made locally and will not be committed back to the main repo.

@yangfanglin It may be included in a future PR targeting the main repo, but that will be a separate, future step.

In the 10m winds we see significant improvements in RMSE in both west and east CONUS. However, a slight degradation of windspeed bias in west (little change in bias in east).

For VSDB verification, go to:

The modifications to TOFD are the experiment "HR3GWD01". "HR2D13" is HR2.

tests are done at ufs-community/ufs-weather-model#2147. @grantfirl can you merge this pr? |
|
@MatthewPyle-NOAA You may go ahead to merge this pr if you have permission. |
|
@jkbk2004 I don't have that permission, at least not yet. |
|
I'll merge it for you |
Thanks! @climbfuji |

@climbfuji Thanks. I got a late start this morning. |
