Chinese scientists have introduced a new air quality simulation system, EPICC, designed to more accurately track fine particulate matter (PM2.5) and ground-level ozone. The model aims to improve understanding of complex pollution patterns, particularly in fast-growing regions where air quality challenges remain severe.
The model was developed through a large-scale collaborative effort involving 59 researchers from 13 institutions, including the Chinese Academy of Sciences, Tsinghua University and Peking University. Built with a modular structure, EPICC allows scientific components to be updated as new atmospheric research emerges, making it more adaptable than older models.
Researchers say EPICC significantly enhances pollution simulation accuracy by addressing key weaknesses in earlier systems, such as underestimating sulfate levels and overestimating ozone during summer months. The model is expected to support policymakers in designing more effective air pollution control strategies in China and other developing countries. The research has been published in Advances in Atmospheric Sciences.
