National Environment Agency (NEA) tracks annual mean concentrations of fine particulate matter (PM2.5) in Singapore’s air. The CSV dataset supports environmental reporting referenced to WHO Air Quality Guidelines in the official description. Public-health researchers and air-quality modellers can study long-term PM2.5 trends for policy and awareness campaigns. This collection is a key Singapore open-data source for ambient air pollution and haze-related analysis.
Official description
Annual means for PM2.5 (µg/m3) are based on WHO Air Quality Guidelines (global update 2005).
National Environment Agency CSV of Singapore’s annual mean ambient PM2.5 concentration from 2002 through 2025, measured in micrograms per cubic metre. Public-health and air-quality analysts track fine particulate trends for haze episodes, health-impact studies, and long-run pollution monitoring.
