Gaussian dispersion model software

Each copy contains everything you'll need to complete your project without paying for costly add-ons. Multi-Chemical Utility Boost your productivity drastically by specifying emissions from several pollutants emitted by the same source. No need to setup different projects for each pollutant! You can include your company logo, project number, and other project specific information. See below technical specifications for these three models:. This product is a Microsoft Windows-based program that can be installed in the following Windows operating systems:.

In this presentation, we discuss the hierarchy of model updates - bug fixes, formulation updates, and enhancements - and then describe the changes implemented by the US EPA into the model releases. This portion of the webinar describes the changes to the AERMOD modeling system including bug fixes, formulation changes, and enhancements.

Learn several ways to how to improve project runtimes. Our most commonly used air dispersion model and is applicable to a wide range of buoyant or neutrally buoyant emissions up to a range of 50km. Also suitable for complex terrain and urban dispersion scenarios. A non-steady state Gaussian puff model, suitable for long range transport, atmospheric chemistry, visibility and scenarios with complex wind fields, such as coastal and complex terrain areas.

A traffic dispersion model specifically designed for modeling emissions from vehicles. CALRoads can model timed intersections, parking lots and account from traffic patterns. Toxics Screening Model TSCREEN is a Gaussian model that implements the procedures to correctly analyze toxic emissions and their subsequent dispersion from one of many different types of possible releases for superfund sites.

CTSCREEN is a Gaussian plume dispersion model designed as a screening technique for regulatory application to plume impaction assessments in complex terrain. AERMET processes commercially available or custom on-site met data and creates two files: a surface data file and a profile data file. This file would contain elevation and hill-height scaling factors for each receptor in the air dispersion study.

Air quality models used to predict pollutant concentration near roadway intersections. We recommend that you get both models. A modeling program to assess air quality impacts near transportation facilities. It is based on the Gaussian diffusion equation and employs a mixing zone concept to characterize pollutant dispersion over the roadway.
