This study uses machine learning (ML) models for a high-resolution prediction (0.1°×0.1°) of air fine particular matter (PM2.5) concentration, the most harmful to human health, from meteorological and soil data. Iraq was considered area implement method. Different lags changing patterns four European Reanalysis (ERA5) variables, rainfall, mean temperature, wind speed relative humidity, one parameter, moisture, were used select suitable set predictors using non-greedy algorithm known as simulated annealing (SA). The selected simulate temporal spatial variability PM2.5 concentration over during early summer (May-July), polluted months, three advanced ML models, extremely randomized trees (ERT), stochastic gradient descent backpropagation (SGD-BP) long short-term memory (LSTM) integrated with Bayesian optimizer. distribution annual average revealed population whole is exposed pollution level above standard limit. changes in temperature moisture humidity month before can predict May-July.

Atmospheric fine particles (PM2.5) have been found to be harmful the environment and human health. Recently, remote sensing technology machine learning models used monitor PM2.5 concentrations. Partial dependence plots (PDP) were explore meteorology mechanisms between predictor variables concentration in “black box” models. However, there are two key shortcomings original PDP. (1) it calculates marginal effect of feature(s) on predicted outcome a model, therefore some local effects might hidden. (2) requires that for which partial is computed not correlated with other features, otherwise estimated feature has great bias. In this study, PDP’s analyzed. Results show contradictory correlation temperature can given by Furthermore, spatiotemporal heterogeneity PM2.5-AOD relationship cannot displayed well The drawbacks PDP make unsuitable exploring large-area effects. To resolve above issue, multi-way recommended, characterize how concentrations changed temporal spatial variations major meteorological factors China.

This review comprehensively explores progress of concentration prediction, covering bibliometric trends, time series data characteristics, deep learning applications, future development directions. article obtained on 2327 journal articles published from 2014 2024 WOS database. Bibliometric analysis shows that research output growing rapidly, with China United States playing leading role, recent increasingly focusing data-driven methods such as learning. Key sources include ground monitoring, meteorological observations, remote sensing, socioeconomic activity data. Deep (including CNN, RNN, LSTM, Transformer) perform well capturing complex temporal dependencies. With its self-attention mechanism parallel processing capabilities, Transformer particularly outstanding addressing challenges long sequence modeling. Despite these advances, integration, model interpretability, computational cost remain. Emerging technologies meta-learning, graph neural networks, multi-scale modeling offer promising solutions while integrating into real-world applications smart city systems can enhance practical impact. provides informative guide for researchers novices, providing understanding cutting-edge methods, systematic paths.
