The Sparse Matrix Operator Kernel Emission (SMOKE) model was developed by the Environmental Modeling Center at MCNC under cooperative research agreements and contracts with the U.S. Environmental Protection Agency (EPA). Development of SMOKE continues at UNC-IE and is partially supported by CMAS.

The emissions data used in this release of CMAQ were prepared with SMOKE.

SMOKE code is open source Fortran90 code, and is consistent with the netCDF I/O API convention used by CMAQ.
