National Environment Agency (NEA) reports annual maximum 24-hour mean concentrations for sulphur dioxide in Singapore’s air quality monitoring network. Figures in micrograms per cubic metre follow WHO Air Quality Guidelines (global update 2005) for long-term comparison. The annual CSV from 2000 through 2022 supports environmental health research alongside other NEA pollutant series on data.gov.sg. Analysts can track industrial and maritime emission influences on ambient SO2 peaks.
