P7.1 preliminary experiments

Model Updates

As code changes are being reviewed and merged in the UFS weather model authoritative repository, I have created two feature branches in my ufs-weather-model fork including the latest model updates to begin running preliminary P7.1 experiments:

• feature/p7.1 This branch includes the GOCART revision we have been testing, with both AOD and FENGSHA fixes.

• feature/p7.1-gocart-dev This branch features NASA's pre-release version of GOCART 2G (2.0 rc1). This version includes:

  • Active brown carbon component (BR).
  • Additional OC biogenic emissions: OC_ISOPRENE, OC_LIMO, OC_MTPA, OC_MTPO
  • Updated optical property labels in GOCART2G_GridComp.rc (AOD fix included):

    aerosol_monochromatic_optics_wavelength_in_nm_from_LUT: 470 550 670 870
    wavelengths_for_profile_aop_in_nm: 550               # must be included in LUT
    wavelengths_for_vertically_integrated_aop_in_nm: 550 # must be included in LUT

  • Configuration files for GOCART2G subcomponents must be renamed as <name>2G_instance_<name>.rc. For example, DU2G_GridComp_DU.rc becomes DU2G_instance_DU.rc
  • Diagnostic output for stratospheric AOD. This requires providing the atmospheric pressure at the tropopause (TROPP). We can use a constant value in AERO_ExtData.rc for the time being. For instance:

    TROPP      'Pa'         Y    N       0     0.0      1.0     TROPP  /dev/null:10000.

  • Latest FENGSHA update

Both of these branches also include:

• proper deep convective transport of aerosols
• full mass conservation for prognostic (non-hydrometeor) tracers
• ability to run the UFS weather model in fully-coupled mode with prognostic aerosols (build with APP=S2SW)

Please checkout either of those branches as follows:

git clone -b feature/p7.1 --recursive https://github.com/rmontuoro/ufs-weather-model.git

or:

git clone -b feature/p7.1-gocart-dev --recursive https://github.com/rmontuoro/ufs-weather-model.git

Workflow Updates

To start testing the branches above with a preliminary (fully-coupled) P7.1 configuration, I've also created a new global workflow branch in my forked repository. This branch supersedes the current feature/aerosols and includes a draft P7.1 case file:

• feature/p7.1
  • Add -u <url> option to checkout.sh to download the ufs-weather-model code from a non-authoritative repository
  • Add case file for P7.1 (prototype7.1.yaml)

You may checkout this global workflow update as:

git clone -b feature/p7.1 --recursive https://github.com/rmontuoro/global-workflow.git    

To use one of the branches above, please download the source code as follows:

cd sorc/
sh checkout.sh -c -r <branch> -u https://github.com/rmontuoro/ufs-weather-model.git

then build using option -c for either atmosphere-aerosol or fully-coupled (P7.1) configurations, or -a only for atmosphere-aerosols runs:

sh build_all.sh -c

Aerosol Configuration Files

Updated configuration files for GOCART 2.0 rc1 (ufs-weather-model branch feature/p7.1-gocart-dev above) are available in the rc.hera folder of this repository's branch feature/p7.1-gocart-dev.

These files can be used as a template for P7.1 experiments. Note that brown carbon (br) has been disabled in current configurations. However, the component can be turned on for testing purposes using the following settings in GOCART2G_GridComp.rc:

ACTIVE_INSTANCES_CA:   CA.oc  CA.bc  CA.br

and configuration file CA2G_instance_CA.br.rc. Two additional tracers also need to be added as done for the BC and OC components.

My runs are here:

run directory /scratch2/NCEPDEV/naqfc/Barry.Baker/p71_2016*

COM /scratch2/NCEPDEV/naqfc/Barry.Baker/COM/p71_2016*

DATA /scratch2/NCEPDEV/naqfc/Barry.Baker/DATA/p71_2016*

@lipan-NOAA is backing these up on HPSS for me

@bbakernoaa @lipan-NOAA May I know which path did you back up at HPSS. I did not see the path as @rmontuoro recommended.

[lipan-NOAA]

@zhanglikate @bbakernoaa @rmontuoro I will archive all ours run to that directory.

Kate, would you let me know where are your outputs located ?

@lipan-NOAA Here are all of my output:

@lipan-NOAA I copied the gocart AOD output from RUNDIR into output DIR and put them into the "chem" folder. Thanks.
