WRF-PartMC

WRF-PartMC is a coupled model that combines the strengths of the Weather Research and Forecast (WRF) model (state-of-the-art mesoscale numerical weather prediction) with the strengths of the particle-resolved aerosol model PartMC (state-of-the-art aerosol dynamics and chemistry capable of resolving complex aerosol composition). This enables the use of high detailed aerosol representation at the regional scale.

Acquiring and building WRF-PartMC

  1. To clone the WRF-PartMC repository:

    git clone https://github.com/open-atmos/wrf-partmc.git

  2. Change into the clone repository:

    cd wrf-partmc

  3. To checkout the PartMC submodule:

    git submodule update --init partmc

  4. And if you have access to MOSAIC, you may check it out it by:

    git submodule update --init mosaic

  5. In order to compile with MOSAIC support, set the environmental variable:

    export MOSAIC=1

    This flag will signal to the WRF-PartMC build process to attempt to build MOSAIC.

  6. WRF-PartMC requires WRF-Chem to be built so set the environmental flag (WRF_CHEM) for WRF-Chem to be included by:

    export WRF_CHEM=1

  7. To configure and compile, follow the process for a standard WRF installation which is:

    cd WRFV3

  8. Set the netCDF path as done for WRF, typically can be done by:

    export NETCDF=$(nc-config --prefix)

  9. You should be ready to configure the model by:

    ./configure

    and select the compiler options as you would do in WRF. WRF-PartMC does not currently support domain nesting. You can still build WRF with nesting enabled but you'll be limited to one domain when enabling PartMC.

  10. To compile WRF-PartMC,

    ./compile em_real

Other choices may include em_rotational, em_les and em_scm_xy. See individual directories in test/ for any specific instructions.

Description of the directories found in this repo

  • WPS/ is the WRF preprocessor that creates the inputs for WRF (version 3.9.1)
  • WRFV3/ is the meteorology model and is a modified version of 3.9.1. NOTE: WPS and WRF should match in version number.
  • partmc/ is a submodule that points to a specific version that is for WRF-PartMC.
  • mozbc/ takes wrfinput and wrfbdy from ./real.exe and populates these files with values from the MOZART output.
  • emissions/ contains the program to create WRF-PartMC emissions from SMOKE source-apportioned data
  • boundary_and_initial_conditions/ contains programs to create initial and boundary conditions from the wrfinput and wrfbdy files using MOZART global model output.
  • interface/ is all the code required to interface WRF with PartMC
  • mosaic/ is the chemistry code which is available by request.
