<p>Linhaipeng: /* Getting started */</p> <hr /> <div>=About WRF-GC=<br /> WRF-GC ([https://gmd.copernicus.org/articles/13/3241/2020/gmd-13-3241-2020.html Lin et al., 2020]; [https://gmd.copernicus.org/articles/14/3741/2021/ Feng et al., 2021]) is a new, online coupled model based on the the regional meteorology model, [https://www.mmm.ucar.edu/weather-research-and-forecasting-model WRF], and the chemical transport model, [http://acmg.seas.harvard.edu/geos/ GEOS-Chem]. The coupling structure is designed to be easy to use, massively parallel, and ready for the future. In particular, either one of the two parent models to be updated independently. This allows WRF-GC to take full advantage of the updates in WRF and GEOS-Chem, respectively, and stay state-of-the-science.<br /> <br /> WRF-GC is open-source and free to use.<br /> <br /> [[File:WRF_GC_two-way_Structure_submitted.png|700px|thumb|center|Architectural overview of the WRF-GC model (v2.0). The WRF-GC two-way Coupler (all parts shown in red) includes interfaces to the two parent models, as well as the state conversion and state management modules. The parent models (shown in grey) are standard codes downloaded from their sources, without any modifications. From [https://gmd.copernicus.org/preprints/gmd-2020-441/ Feng et al. (2021).] ]] <br /> <br /> <br /> The development of WRF-GC was led by [https://jimmielin.me/ Haipeng LIN], [[Xu FENG]], and [[Tzung-May FU]]. In addition, the GEOS-Chem Support Team provided valuable assistance in updating the GEOS-Chem code to accommodate the coupling.<br /> <br /> <br /> ==Version history==<br /> <br /> ===Version 2.0===<br /> (updated June 24, 2021)<br /> WRF-GC v2.0 ([https://gmd.copernicus.org/articles/14/3741/2021/ Feng et al. (2021)]) is an online two-way coupling of the Weather Research and Forecasting (WRF) meteorological model (v3.9.1.1) and the GEOS-Chem chemical model (v12.7.2). WRF-GC v2.0 is built on the modular framework of WRF-GC v1.0 and further includes aerosol-radiation interactions (ARI) and aerosol-cloud interactions (ACI) based on bulk aerosol mass and composition, as well as the capability to nest multiple domains for high-resolution simulations.<br /> <br /> Major features of WRF-GC v2.0:<br /> * Updated compatibility with the latest release of GEOS-Chem v12.8.1<br /> * Aerosol-radiation interactions and aerosol-cloud interactions that can be turned on/off<br /> * Nested-domain functionality<br /> * Online lightning NOx emissions<br /> * Restart run functionality<br /> * Bug fixes from v1.0<br /> <br /> ===Version 1.0===<br /> The first version of WRF-GC (v1.0) ([https://gmd.copernicus.org/articles/13/3241/2020/gmd-13-3241-2020.html Lin et al., 2020]) was released on January 4, 2019. A more mature and stable version (v 1.0) was released in Fall 2019. <br /> <br /> (updated Feb 26, 2021) We recommend that all users upgrade to WRF-GC v2.0.<br /> <br /> A few notes about v1.0: <br /> * The coupling between WRF and GEOS-Chem is one-way only, i.e., there is no feedback from GEOS-Chem to WRF. <br /> * The nested domain capability of WRF is not yet supported.<br /> <br /> <br /> ==WRF-GC reference==<br /> # '''Lin, H.''', '''Feng, X.''', '''Fu, T.-M.*''', '''Tian, H.''', '''Ma, Y.''', '''Zhang, L.''', Jacob, D.J., Yantosca, R.M., Sulprizio, M.P., Lundgren, E.W., Zhuang, J., Zhang, Q., Lu, X., Zhang, L., Shen, L., Guo, J., Eastham, S.D., Keller, C.A.

<p>Linhaipeng: </p> <hr /> <div>= System Requirements =<br /> WRF-GC requires a set of compilers and libraries that are compatible with the WRF model and the GEOS-Chem High Performance model.<br /> <br /> Recommended system setup (as tested):<br /> <br /> * Compiler: [https://software.intel.com/en-us/intel-compilers Intel 15]. There is limited support for the PGI and gfortran compilers.<br /> <br /> * [http://mvapich.cse.ohio-state.edu/downloads/ MPI Library: MVAPich2 Version 2.3]<br /> <br /> * [http://www.zlib.net/ zlib]<br /> <br /> * [https://support.hdfgroup.org/HDF5/release/obtainsrc518.html HDF5 1.8]<br /> <br /> * [https://www.unidata.ucar.edu/downloads/netcdf/index.jsp NetCDF-C 4.6.1]<br /> <br /> * NetCDF-Fortran 4.4.4<br /> <br /> * [https://www.ece.uvic.ca/~frodo/jasper/#download JasPer 1.900.29]<br /> <br /> It is recommended that you install all libraries in the same location (using the --prefix=/your/directory/here when calling the configure script). <br /> <br /> For WRF to correctly find those libraries, you need to set the HDF5 & NETCDF environmental variables to point to the directory (which includes the bin, lib, include directories) where those libraries are installed. <br /> <br /> For example, if you have used /your/directory/here below, you should be able to see bin, lib and include directories under this directory and point the necessary environmental variables to them:<br /> <br /> $ ls /your/directory/here<br /> bin lib share include<br /> <br /> $ export HDF5="/your/directory/here"<br /> $ export NETCDF=$HDF5<br /> <br /> You are also recommended to review the [http://wiki.seas.harvard.edu/geos-chem/index.php/Installing_libraries_for_GEOS-Chem GEOS-Chem library installation] guide.<br /> <br /> = Installing WRF-GC =<br /> <br /> After obtaining the WRF and WRF-GC code in the [[Downloading WRF-GC]] step, you will need to set up the compile environment as follows:<br /> <br /> * Set the environmental variables WRF_EM_CORE = 1, WRF_NMM_CORE = 0, and WRF_CHEM = 1 in your shell.<br /> <br /> * Configure WRF using the hybrid sigma-eta grid option using the configure script, setting the distributed-memory parallel (dmpar) version of WRF with the Intel C and Fortran compilers. There is limited support for PGI and gfortran compilers, but they are not recommended for this alpha build.<br /> <br /> * After configuration please navigate to the WRF-GC "chem" directory, and issue the following command: make install_registry. '''This step is critical and must be done manually before compilation.'''<br /> <br /> * Compile WRF-GC using the ./compile em_real command.<br /> <br /> We suggest you to review the [http://www2.mmm.ucar.edu/wrf/users/docs/user_guide_V3.9/users_guide_chap1.htm WRF User's Guide (v3.9)] for additional installation information.</div>

<p>Linhaipeng: /* System Requirements */</p> <hr /> <div>== System Requirements ==<br /> WRF-GC requires a set of compilers & libraries that are compatible with the WRF model & the GEOS-Chem High Performance model.<br /> <br /> Recommended system setup (as tested):<br /> <br /> - Compiler: Intel 15.<br /> <br /> - MPI Library: MVAPich2 Version 2.3 (http://mvapich.cse.ohio-state.edu/downloads/)<br /> <br /> - zlib (http://www.zlib.net/)<br /> <br /> - HDF5 1.8 (https://support.hdfgroup.org/HDF5/release/obtainsrc518.html)<br /> <br /> - NetCDF-C 4.6.1 (https://www.unidata.ucar.edu/downloads/netcdf/index.jsp)<br /> <br /> - NetCDF-Fortran 4.4.4<br /> <br /> - JasPer 1.900.29 (https://www.ece.uvic.ca/~frodo/jasper/#download)<br /> <br /> It is recommended to install all libraries in the same location (using the --prefix=/your/directory/here when calling the configure script). For WRF to correctly find those libraries, you need to set the HDF5 & NETCDF environmental variables to point to the directory (which includes the bin, lib, include directories) where those libraries are installed.<br /> <br /> Obtain the WRF model and the WPS pre-processing system. Recommended version is WRF v3.9.1.1. Only WRF version 3.9+ is supported as it provides the hybrid sigma-eta vertical grid functionality required by GEOS-Chem.
