NEA monitors carbon monoxide in Singapore’s ambient air through this annual pollutant collection. The CSV tracks maximum eight-hour mean CO concentrations referenced to WHO guidelines, complementing other NEA air-quality datasets on ozone, PM2.5, and more. Environmental researchers and air-quality modellers working on Singapore urban emissions can use the 2000–2021 series for trend analysis and regulatory context. Download the member dataset Air Pollutant - Carbon Monoxide (Maximum 8-Hour Mean) for machine-readable values.
Annual maximum 8-hr means for carbon monoxide (mg/m3) are based on WHO Air Quality Guidelines (for Europe, 2000).
National Environment Agency annual CSV of Singapore’s maximum 8-hour mean carbon monoxide (CO) levels from 2000 through 2025. Environmental and public-health analysts monitor peak CO exposure against air-quality standards.
