JEDI-METplus

Workflow to interface JEDI component (generic-interface) and METplus for constituents model evaluation.

Clone the code

Clone this repo recusively with the command below git clone https://github.com/weiwilliam/JEDI-METplus.git <folder>

Supported platforms

• Platforms with JCSDA spack-stack package, now provide derecho_intel module loading script.

Supported (Tested) models

• Lambert CC projection: WRF-Chem
• Regular Lat-Lon (under testing)

Supported (Tested) measurements

• TropOMI NO2 and CO
• VIIRS AOD
• TEMPO NO2

Use of this interface

• Prerequisites: observation files in IODA format and model outputs in NetCDF (GRIB2 may be supported later).

1. Create Python venv under your repo, source ush/setup.sh </repo/path> <platform> <compiler>
2. Based on your application, copy a main yaml file from yamls/main and a hofx3d yaml file from yamls/hofx3d. <e.g., evaluate wrf-chem trace gas, copy main/main_wrfchem.yaml and hofx3d/hofx3d_lambertCC.yaml>
3. Update the main and hofx3d yaml files as needed. Check README.md under yamls/<main/hofx3d> for details.
4. Execute pyscripts/genint_vrfy.py <main yaml>

Installation of generic interface

1. Create the <repo>/genint-bundle/build folder
2. export GENINT_BUILD=<path/to/build/genint>
3. source ush/setup.sh <repo path> <platform> <compiler>
   • It will create the virtual env <repo>/venv first
4. cd <path/to/build/genint>
5. ecbuild <path/to/genint-bundle>
6. make -j<n>
7. ctest to check executables work properly
