Air Quality Modeling - ufs-community/ufs-srweather-app GitHub Wiki

This page is for the main_aqm branch to support Air Quality Modeling (AQM) and Smoke and Dust (SD). This is available on Hera, Orion, and Hercules as of 10/31/2024.

Quick Start Guide

1. Clone the "main_aqm" branch of the authoritative repository:

   git clone -b main_aqm https://github.com/ufs-community/ufs-srweather-app.git
   cd ufs-srweather-app/sorc
   

2. Build the app:

   • Air Quality Modeling (coupled):

   ./manage_externals/checkout_externals -e Externals_aqm.cfg
   ./app_build.sh -a=ATMAQ
   

   • Smoke and Dust (uncoupled):

   ./manage_externals/checkout_externals -e Externals_smoke_dust.cfg
   ./app_build.sh
   

3. Set up the user-specific configuration:

   cd ../parm
   cp config.[application].yaml config.yaml
   

   Where [application] is aqm for air quality modeling, orsmoke_dust for smoke/dust modeling.

   Set the following parameters in config.yaml for the automatic initial-submission and re-submission by cron:

   workflow:
     USE_CRON_TO_RELAUNCH: true
     CRON_RELAUNCH_INTVL_MNTS: 3
   

   This means that cron will submit the launch script every 3 minutes. Note that you should create your crontab with "crontab -e" first, if this is your first time using cron.

4. Load the Python environment for the workflow:

   module purge
   source ../versions/run.ver_[machine]
   module use ../modulefiles
   module load wflow_[machine]
   

   Where [machine] is hera, orion, or hercules.

5. Generate the workflow:

   ./generate_FV3LAM_wflow.py
   

6. Run the workflow only if USE_CRON_TO_RELAUNCH: true was not set in config.yaml(see Step 3 for the automatic resubmission by cron):

   cd ../../expt_dirs/[EXPT_SUBDIR]
   ./launch_FV3LAM_wflow.sh
   

   Repeat this launch command until you have SUCCESS or FAILURE on your terminal window.
