Title: Artificial Intelligence for PM2.5 Forecasting in Chiangmai: Enhancing Public Health and Environmental Policy

Abstract:

Particulate matter 2.5 poses a significant threat to human life. Over the past decade, there has been a substantial increase in the number of articles dedicated to studying and forecasting PM2.5 concentrations. Thailand, particularly Chiang Mai, has elevated levels of dangerous PM2.5 throughout the hot season. The primary objective of this study is to evaluate the efficacy of three widely used machine learning models — artificial neural networks, long short-term memory networks, and convolutional neural networks — in predicting the levels of PM2.5 particles in Chiang Mai. The raw data were obtained from the Pollution Control Department, Ministry of Natural Resources and Environment, Thailand, between January 2014 and June 2023, a total of 3,468 observations.
