@lipan-NOAA could you give a little more context for what is happening? Is this extremely localized and does it persist? Is this due to a specific species (OC, BC or DUST)? What is the wet scavenging settings?

I noticed that you did not use the latest develop branch for your configuration files. There are several updates and we have been seeing fairly stable runs.

What branch of the UFS-Aerosols are you using? Is this the feature/p7.1?

@bbakernoaa It happened everywhere near the surface for all species. I did not do any changes on scavenging settings, which are defined in rc.file. And I compared my rc.file to Kate's, except for extdata.rc and history.rc, there are no big differences. Since I am focusing on engineering test at this moment, I don't think it will make big differences.

I am still using feature/aerosols, and I am going to upgrade it to feature/p7.1.

bbakernoaa commented 3 years ago

@lipan-NOAA. I highly suggest you upgrade to feature/p7.1 there a few fixes in it and use the develop branch of this repository for the configuration files.

Could you provide some plots?

Btw the scavenging factors are not set in the .rc files. The values must be present in those values but only used internally for nasa. The values used in UFS-Aerosols are found in your case yaml file.

Please use the configuration repository so that we can keep track of setting and are sure of the co figurations. We went through this with GEFS and were never completely sure what exactly was being done.

@lipan-NOAA - Your global-workflow directory (/scratch2/NAGAPE/arl/Li.Pan/global-workflow/sorc/ufs_coupled.fd) shows that your experiment used a code revision not recommended for testing:

url: https://github.com/ufs-community/ufs-weather-model hash: 22613e8 (July 20)

This version does not include a crucial update to the convective transport that fixes the unrealistic high mixing ratios you reported. The update was applied on August 12.

Please follow the instructions listed in issue #14 and do not use model revisions other than those recommended in issue #14.
