Air Pollutant - Nitrogen Dioxide

National Environment Agency (NEA) publishes annual mean nitrogen dioxide concentrations for Singapore based on WHO Air Quality Guidelines (2005 global update). The Air Pollutant - Nitrogen Dioxide CSV supports long-term air-quality monitoring and public health research from 2000 through 2022. Analysts can relate the series to transport emissions and urban exposure patterns. The indicator is reported in micrograms per cubic metre (µg/m³).

Air Pollutant - Nitrogen Dioxide

National Environment Agency annual CSV of Singapore's nitrogen dioxide annual mean concentration from 2000 through 2025. Each row pairs a year with the NO2 mean, giving a compact long-run series of ambient nitrogen dioxide levels, a pollutant associated largely with vehicle exhaust, power generation, and industrial combustion. Environmental researchers and policy analysts use it to assess progress against air-quality targets and to relate NO2 trends to traffic growth and changes in the energy mix. The series also serves as background exposure data for public-health and epidemiological studies in Singapore.
