Human activities have emitted huge amounts of pollutants into the Earth system since the Industrial Revolution with the usage of fossil fuels (Crippa et al., 2018). Consequently, these emitted air pollutants deteriorate air quality and exert climate consequences (e.g., global warming and related devastating hazards), which poses a threat to human health and ecosystem balance on Earth (Kang et al., 2019). It is very challenging but extremely important to precisely predict air pollution and climate change under different mitigation scenarios, thereby providing scientific evidence for policymakers to make wise decisions and minimize losses due to unavoidable consequences. In recent years, data science has progressed rapidly to develop new understanding from data-driven approaches, and the advance in modern observations (such as satellite remote sensing and in situ observational network) provides large amount of data for the better understanding of atmospheric pollution (Chen et al., 2020) and climate change (Chen et al., 2022). The marriage of these two advances has attracted considerable attention as a powerful tool to tackle complex issues, and more applications have been developed in air pollution prediction and big data analysis in climate science (Jones, 2017). The aim of this Research Topic was to advance our understanding of air pollution and climate change using machine learning methods. Within this Research Topic, five articles with contribution from 32 authors are published. Key messages from each article are highlighted in the following paragraphs.
Ma et al. combined an ensemble machine learning model and satellite observations to generate a pollution distribution map for the electric power system in Yunnan Province, China. They found that this new method and remote sensing data are very helpful in identifying high-pollution areas and therefore could be useful for advising policymakers.
Wang et al. developed a deep learning-based emulator for a sophisticated gas-phase chemical scheme. This emulator is 300–750 times more efficient than the original scheme module. They coupled this emulator with an air quality model and showed a similar accuracy to that of the original module. Their work well demonstrates the high potential of machine learning in advancing process-based models.
Ke et al. developed a data science model to optimize the outcomes of an air quality numerical model. They found that this approach can largely improve model’s capability in predicting highly polluted events in China. Their work demonstrates a promising prospect of machine learning in environment forecast and pollution precautions.
Zhu et al. applied a deep learning approach to calibrating surface air temperature forecast in Xinjiang Province, China. They found that high forecast biases are mainly distributed over mountain regions, and the proposed approach is able to improve the forecast skill.
Yuan et al. used the periodical canonical correlation analysis method to analyse multi-angle simultaneous polarization observations of particulate matter in the atmosphere in Shanghai, China. They found that this advanced data analysis approach is better than traditional methods (such as locally weighted linear regression and autoregressive moving average) in predicting particulate matter concentrations in the atmosphere.
Overall, this Research Topic highlights new prospects that modern machine learning methods bring to us to address challenges in the complex atmospheric and climate system. We hope that more interdisciplinary studies will be carried out at the interface of data science and atmospheric science. Finally, we would like to thank all the authors and the reviewers for their contributions.
