Smkreport can only be used after at least Smkinven (for inventory import) has been run. Depending on the reporting options selected in the REPCONFIG input file, other processing steps may need to have been run. For example, to create a report of county total emissions after gridding, the Grdmat (for spatial allocation) program must have been run already to create the gridding matrix. Smkreport can use output files from the following programs: Smkinven, Temporal (for temporal allocation), Spcmat (for chemical speciation), Grdmat, Elevpoint (for elevated source selection), Laypoint (for plume rise calculations), and Cntlmat.
