3.2. Installing CMAQ Source Code
After installing CVS, the IOAPI and netCDF libraries, and Fortran and C compilers on the hardware system, download the CMAQ
source code, scripts, and benchmark data files from the CMAS Center website (http://www.cmascenter.org). After registering to download CMAQ on the CMAS Center Software Clearinghouse users are redirected to a page that contains
links to download UNIX tar files of the CMAQ code, scripts, and benchmark data along with various documents describing the
installation and execution processes.
The following files and archives comprise the CMAQ distribution:
- README - text file describing the CMAQ installation
- CHEM_SOLVER_NOTES - text file containing comments on chemical solvers available in CMAQ and their relative computational performance
and numerical accuracy
- CVS_NETCDF - text file explaining the CVS configuration management system and the netCDF data system and how to set them up
- IOAPI - text file explaining how to get the I/O API system and set up the libraries
- SMOKE - text file describing the SMOKE emissions system and how to set it up (not required for the tutorial simulation)
- PARALLEL_NOTES - text file containing comments related to running the CMAQ CCTM in Linux MPICH clusters
- PROCESS_ANALYSIS_NOTES - text file containing comments related to running the CMAQ CCTM with process analysis
- PING_PDM_NOTES - text file containing comments related to running the CMAQ CCTM with plume-in-grid treatment
- TUTORIAL_PROCEDURE - text file describing how to work through the tutorial
- RELEASE_NOTES - text file containing a list of the changes since the last release
- MODELS.tar.gz - gzipped tar file (~2.3 Mb) containing model, tools and libraries source code CVS archives
- M3DATA.tar.gz - gzipped tar file (~106 Mb) containing the required datasets not produced by this package
- SCRIPTS.tar.gz - gzipped tar file (~17 Kb) containing C-Shell scripts to build and execute the CMAQ models
- M3DATA_REF.tar.gz - gzipped tar file (~315 Mb) containing reference data to compare with datasets produced by the tutorial
on a Linux workstation
The default CMAQ installation is configured for a Red Hat Linux system, and the Portland Group FORTRAN compiler.
