Special Issue Information

Dear Colleagues,

The rapid urbanization and industrialization of recent decades have significantly impacted global air quality, posing severe health and environmental risks. The increased prevalence of airborne pollutants such as particulate matter (PM), volatile organic compounds (VOCs), carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), polycyclic aromatic hydrocarbons (PAHs), and other hazardous pollutants has heightened the need for effective air quality monitoring and control mechanisms. Advancements in machine learning and data modeling have paved the way for innovative approaches to addressing these challenges, enabling precise pollutant detection, forecasting, and real-time intervention strategies.

This Special Issue on “Applications of Machine Learning and Data Modeling Techniques in Air Quality Monitoring and Control Mechanisms” seeks high-quality research and innovative solutions in this critical domain. Authors are invited to submit original research, case studies, or review articles on topics including, but not limited to, the following:

  • IoT-based air quality monitoring systems and their seamless integration into smart environments;
  • Ground vehicle-based sensor and unmanned aerial vehicle-based sensor monitoring systems;
  • Data-driven approaches for real-time air quality assessment and monitoring;
  • Development of machine learning models for air quality prediction and forecasting;
  • Innovations in data fusion and visualization for air quality analytics;
  • AI applications in designing effective pollution control strategies;
  • Predictive models for assessing health risks associated with air pollution exposure;
  • Case studies and practical implementations of air quality management systems.

To better inform the public about ambient air quality and associated health risks and prevent cardiovascular and chronic respiratory diseases in Macau, the local government authorities apply the Air Quality Index (AQI) for air quality management within its jurisdiction. The application of AQI requires first determining the sub-indices for several pollutants, including respirable suspended particulates (PM10), fine suspended particulates (PM2.5), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), and carbon monoxide (CO). Accurate prediction of AQI is crucial in providing early warnings to the public before pollution episodes occur. To improve AQI prediction accuracy, deep learning methods such as artificial neural networks (ANNs) and long short-term memory (LSTM) models were applied to forecast the six pollutants commonly found in the AQI. The data for this study was accessed from the Macau High-Density Residential Air Quality Monitoring Station (AQMS), which is located in an area with high traffic and high population density near a 24 h land border-crossing facility connecting Zhuhai and Macau. The novelty of this work lies in its potential to enhance operational AQI forecasting for Macau. The ANN and LSTM models were run five times, with average pollutant forecasts obtained for each model. Results demonstrated that both models accurately predicted pollutant concentrations of the upcoming 24 h, with PM10 and CO showing the highest predictive accuracy, reflected in high Pearson Correlation Coefficient (PCC) between 0.84 and 0.87 and Kendall’s Tau Coefficient (KTC) between 0.66 and 0.70 values and low Mean Bias (MB) between 0.06 and 0.10, Mean Fractional Bias (MFB) between 0.09 and 0.11, Root Mean Square Error (RMSE) between 0.14 and 0.21, and Mean Absolute Error (MAE) between 0.11 and 0.17. Overall, the LSTM model consistently delivered the highest PCC (0.87) and KTC (0.70) values and the lowest MB (0.06), MFB (0.09), RMSE (0.14), and MAE (0.11) across all six pollutants, with the lowest SD (0.01), indicating greater precision and reliability. As a result, the study concludes that the LSTM model outperforms the ANN model in forecasting air pollutants in Macau, offering a more accurate and consistent prediction tool for local air quality management.
