SCREEN SPR : A SCREENING MODEL FOR ASSESSING THE AIR QUALITY IMPACT OF STATIONARY SOURCE

Abstract

The Air quality modeling systems were imported from SCRAM of US Environmental Protection Agency (EPA). The suggested modeling system included SCREEN3, AERMOD, ADMS and CALPUFF were provided by EPA in the form of FORTRAN source codes. However, the programs were written as console applications, and they are inconvenient to the end users. It is necessary to develop a software tool which runs in windows platform. SCREEN-SPR is a software package as similar to the USEPA SCREEN3Model was developed in C# language and run on the VisualBasic platform which can be used as a tool for assessing the air quality impact of stationary source with preliminary estimation scheme (screening scheme). Also, theSCREEN SPR model is used to calculate the maximum Ground Level Concentration (GLC)of pollutant which prevail at the shortest downwind locations from the source under the combinations of various possible wind speed andits corresponding atmosphericsabilityclassesfor thegiven inputs such as source details and plant emission characteristics.
