A hierarchical ensemble approach for multi-country PM10 forecasting using LightGBM and residual neural network
Syed Azeem Inam, Haider Rajput, Saddam Umer · 5 Jan 2026
Accurate day-ahead forecasting of particulate matter (PM10) concentrations is critical for public health interventions, regulatory compliance, and urban air quality management. However, existing approaches suffer from temporal leakage, single-city limitations, inadequate hierarchical modeling of geographic dependencies, and reliance on single-model architectures that fail to capture complex nonlinear pollution dynamics. This study presents a novel three-stage…
Assessing AQI of air pollution crisis 2024 in Delhi: its health risks and nationwide impact
Abhranil Bhuyan, Tapoban Bordoloi, Rabin Debnath et al. · 10 Jun 2025
Air pollution is a broad concern around the world due to its severe impacts on health as well as on the environment. In India, Delhi's growing air pollution has attained dangerous levels in 2024, ranking it among the world's most polluted cities. The city's Air Quality Index (AQI) regularly falls into the "severe" or "hazardous"…
Model performance and surface impacts of atmospheric river events in Antarctica
Marlen Kolbe, José Abraham Torres‐Alavez, Ruth Mottram et al. · 17 Mar 2025
There is increasing evidence that atmospheric rivers (ARs) drive extreme precipitation and melt events across Antarctica and that these impacts are more accurately captured in high-resolution models. However, a comprehensive evaluation of AR impacts, comparing the performance of models with varying resolutions and physics across multiple AR events, has not yet been conducted. In this…
Impact of different crop residue burning activities on seasonal variation in ambient air quality
Prashant Ravish, Smita Chaudhry, Abhishek Sharma · 15 Jul 2025
The large-scale burning of rice, wheat, and sugarcane residues significantly impacts air quality, contributing to climate change and severe health risks. This study aims to analyze the seasonal variations in pollutant levels along with meteorological factors. The findings revealed that rice residue burning leads to a 57.7% increase in the PM 2.5 concentration above the…
Analysis of spatiotemporal distribution of air quality index (AQI) in the state of West Bengal, India from 2016 to 2021
Buddhadev Ghosh, Harish Chandra Barman, Pratap Kumar Padhy · 8 Dec 2023
Abstract The ambient air quality is progressively declining, especially in emerging countries, due to increased urbanization, high demands of energy, and industrialization. High risks to human health and environmental degradation are associated with air pollution. The analysis of the Air Quality Index (AQI) serves as a valuable tool for simplifying the communication of air quality…
