Air Quality Modelling Tools
Description
Repository for the Simple Interactive Models for better air quality set of tools. These tools demonstrate fundamental equations to calculate, visualize, and interpret air emissions and pollution. The tools are intended to make links between emissions, pollution dispersion, impacts, and potential solutions more accessible to a wider set of stakeholders. The tools include models as well as primers on different air quality topics.
Questions this resource can help answer
How can use simplified modeling to examine the impact of emissions control strategies on air quality in my city?
How do I use this resource?
This website provides a set of tools and resources that allows users to conduct their own modeling of air quality, as well as create scenarios that link emissions reductions to changes in air quality. The tool was developed for application in India, however, the models seem generalizable to other geographies. The key tools include the SIM-Air reduced complexity air quality model, which is a spreadsheet based tool with simple source-receptor conversions of emissions to sulfur dioxide, nitrogen dioxide, and PM concentrations. The tool also allows for scenario analysis for optimizing emissions reductions to meet air quality targets. There are also emissions calculators for mobile and stationary sources, also spreadsheet based. There is also a simplified lagrangian dispersion model that can generate a source receptor matrix for use in the SIM-Air model.
