This deliverable contains, as a hyperlinked on-line Multimedia document, a short description and introductory documentation of the main air quality models used for the MUTATE model server.
The basic air quality model used in MUTATE is the Inudstrial Source Complex model (ISC) of the US EPA. ISC is a steady-state Gaussian dispersion model that is available both in a short-term version for individual episodes of, say,
one hour averaging time, or as a seasonal long-term model. ISC-3, while using the basic Gaussian steady-stae solution to the dispersion equations that is based on the simplifying assumption of a homogeneous wind field throughout the mdodel domain, introduces a number of corrections and modifications that makes the model more suitable for complex terrain.
A more recent version of the ISC famili of models is the new AERMOD system that is developed from ISC.
ISC (Industrial Source Complex Model) has been specifically developed to simulate air pollution due to an industrial plant, taking accurately into account the effect of high stacks on the behaviour of the pollutant plume. It may be applied in urban or rural environment with a moderately complex terrain. Its numerous options allow to compute the dry deposition of the pollutant downwind the stacks, to model the plume hight accounting for the hydrodinamical effects, to simulate the impact of linear, area and volumetric sources. It works with non reactive pollutant, including particulate matter, but may include a first order decay.
The program has two versions. In the long term version (ISCLT), it computes average concentration values on an area of few hundred square kilometers for a period like a season or a year, on the basis of the correspondent meteorological data. The short term version (ISCST) computes mean concentration values for a period of one or few hours.
