Pollutant Standards Index (PSI)
National Environment Agency (NEA) publishes realtime open data on Singapore’s Pollutant Standards Index (PSI), including overall and regional readings. The legacy API dataset covers 24-hour PSI together with pollutant concentrations and sub-indices used in national haze and air-quality reporting. Researchers and app developers can integrate historical PSI feeds dating from February 2016 for situational awareness during transboundary smoke episodes. The collection anchors NEA’s environmental monitoring releases on data.gov.sg alongside other air-quality statistics.
