Information about SMOKE - 22 September 2006 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-CEP 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. A full description of SMOKE, and its capabilities is available at http://www.smoke-model.org The most recently released version of SMOKE (version 2.2) may be downloaded from http://www.smoke-model.org A user manual, including file formats, a separate test case and other relevant links are available on the SMOKE page. Click on "Download SMOKE" to access the SMOKE code and specific installation instructions for your system. Additional inventory documentation and SMOKE datasets developed for the Clean Air Interstate Rule (CAIR) are available at: http://www.epa.gov/air/interstateairquality/technical.html
