Celebrating under Hazy Skies: Particulate Matter Pollution during Diwali and New Year Festivities in Contrasting Environments - Dataset

The dataset contains measurements of particulate matter (PM) air pollution collected during festival events in two locations: Malda, India (during Diwali, 2023-2024), and Warsaw, Poland (during New Year's Eve, 2023-2024). Data includes concentrations of PM10, PM2.5, PM1 measured at different time intervals both indoors and outdoors. These measurements are intended to assess the impact of festival-related firecracker use on air quality.
