Source-Receptor Matrix


  • Set ichem=1 so that each source location has its own concentration grid
  • Multiple sources run simultaneously
  • Model output results are treated as a matrix
  • Each row represents a source, a concentration grid cell per column
  • Each column receptor, the rows represent the contribution from each source
