Municipalities are required to develop an Air Quality Management Plan (AQMP) in order to work towards mitigating the negative impacts of air quality on human health and the environment. The 2016 AQMP for the City of Johannesburg (CoJ) incorporated photochemical modelling to assist in air quality “hotspot” and scenario analyses. The complex emission source profile of CoJ (like many urban areas) necessitated the use of a one-atmosphere chemistry model. The Comprehensive Air Quality Model with Extensions (CAMx) photochemical model was used to accomplish this. A regional and CoJ specific emissions inventory was developed for both management and modelling purposes; which fed into the model hotspot analysis (also as a baseline) and the basis of the scenarios. This paper will present the various methodologies employed to effectively apply CAMx in CoJ, results and strengths and limitations encountered in the process.
