Unit VII Assessment#1 Gaussian Plume Models Essay

Unit VII Assessment#1 Gaussian Plume Models - Essay Example Screen 3 models are an air pollution dispersion method used to investigate environmental aspect and condition of the atmospheric air (Livermore, 1998).it is a model designed to estimate worst case ground level concentrations of a single source as well as that in a cavity zone and the concentrations resulting from inversion break and shoreline fumigation. Therefore, SCREEN3 is a screening version of the ISC3 modeling. Its initial modeling works towards removing the need for a complicated modeling and helps in saving time and resources (Gaujar, 2010). It was developed in 1995 following the Gaussian plume modeling to cover regional scales. (Nieuwstadt and Dop, 1975). SCREEN3 has various advantages compared to other modeling types. First, it investigates ground level concentrations over large zones saving on time consumptions and minimizing resource inputs. It also covers models over any terrain while setting up any sources and pollutants in one file, it sets thresholds concentrations quickly while identifying specified value. In addition it analyses results in different formats such as graphical, text and use of tables (Nieuwstadt and Dop,
