Simplified Atmospheric Transport Modeling System (ATMoS-4.0) for the SIM-air Tool
In the SIM-air tool, all the calculations, including the conversion of emissions to concentrations, are conducted in Excel, using the source-receptor transfer matrix. The transfer matrix, which enables the conversion of emissions to concentrations, is based on a dispersion model, which is not included the Excel analytical tool. This part of the calculations (generating the matrix) is conducted outside the SIM-air tool and then transferred into Excel to enable further analysis to health impacts and optimization. This paper describes a simplified dispersion model ATMoS-4.0 to generate the transfer matrix using minimum data inputs for direct use in SIM-air for urban applications.
