The dataset spans from October 27 to November 5, 2024, and is divided into three temporal phases: Pre-Diwali (October 27\u201330), Diwali (October 31\u2013November 1), and Post-Diwali (November 2\u20135). Satellite-derived aerosol products, including Aerosol Optical Depth (AOD), Absorbing Aerosol Index (AAI), and Ultraviolet Aerosol Index (UV-AI), were accessed from the MODIS Terra and Copernicus datasets using the Google Earth Engine (GEE) platform. Meteorological parameters such as 2\u00a0m air temperature, dewpoint temperature, relative humidity, surface pressure, and boundary layer height were also retrieved via satellite observations using GEE. All data sources are publicly accessible, and scripts for data extraction, processing, and analysis have been made available on GitHub for reproducibility.
