PyBox: An automated box-model generator for atmospheric chemistry and aerosol simulations

Air pollution and climate change are two of the biggest multidisciplinary challenges in society today. The need to understand the chemical and physical processes in the atmosphere that dictate the impacts of both has created a wide range of research platforms. These include numerical models. Volatile organic compounds (VOCs), emitted from both natural and anthropogenic sources, are oxidised in the atmosphere to form lower-volatility species that form organic particulate matter in the atmosphere through gas-to-particle partitioning. Chemical mechanisms, such as the Master Chemical Mechanism (MCM) (Jenkin, Saunders, Wagner, & Pilling, 2003), have been built to hold information of all relevant species and reactions in the atmosphere.
