CMAQ
CMAQ (Community Multiscale Air Quality Modeling System (CMAQ) is a suite of Fortran 90 programs that work in concert to estimate ozone, PM, toxic compounds, and acid deposition throughout the troposphere.[1]
Installed Version
CMAQ 5.2 is installed on Proteus. Use the modulefile:
cmaq/intel/2015/5.2
This sets the environment variables CMAQ_HOME, CMAQ_DATA, and paths

The code is compiled as MPI parallel, as well as multithreaded, linking to Intel's Math Kernel Library (MKL) for performance.
