Optimized Air Quality Index and Meteorological Predictions with Machine Learning and IoT

Abstract

Air Quality Index (AQI) prediction and forecasting play pivotal roles in assessing and managing air pollution, contributing to public health and environmental sustainability. This paper provides a comprehensive review of recent advancements, methodologies, challenges, and future directions in AQI prediction and forecasting. Recent research has seen a surge in the development of machine learning, statistical, and hybrid models for AQI prediction. These models leverage various input data sources such as meteorological data, satellite imagery, and pollutant emissions data to enhance prediction accuracy. Furthermore, the integration of advanced techniques like deep learning and ensemble modeling has shown promising results in capturing complex nonlinear relationships and improving forecast precision. Challenges persist, including the need for real-time data integration, model interpretability, and addressing spatial and temporal variations in air quality. Additionally, the impact of emerging factors such as climate change and urbanization on AQI prediction requires further investigation. Future research directions focus on the development of hybrid models that integrate multiple data sources, including sensor networks and IoT devices, to improve spatial and temporal resolution. Moreover, there is a growing emphasis on the incorporation of uncertainty quantification techniques to provide probabilistic forecasts and enhance decision-making under uncertainty. In conclusion, this paper underscores the importance of AQI prediction and forecasting in addressing air pollution challenges and promoting public health. By advancing methodologies, addressing challenges, and exploring emerging research avenues, we can strive towards more accurate, reliable, and actionable AQI predictions for sustainable urban development and environmental stewardship.
