Historical 1-hr PM2.5

NEA regional PM2.5 monitoring underpins this Singapore air-quality archive of historical one-hour readings. The CSV Historical 1-hr PM2.5 supports haze post-mortems, health impact studies, and calibration of air-quality models across 2014–2020 coverage. Environmental scientists and journalists covering Singapore transboundary smoke episodes can download microgram-per-cubic-metre values for time-series analysis. Pair the collection with NEA pollutant guideline datasets for regulatory context.

Historical 1-hr PM2.5

National Environment Agency hourly historical PM2.5 readings for Singapore, measured in micrograms per cubic metre and covering April 2014 through May 2026 across more than 105,000 rows. Each record gives a timestamp together with concurrent readings for the North, South, East, West, and Central regions, allowing fine-grained comparison of fine-particulate pollution across the island. Air-quality researchers, health analysts, and developers use the series to study haze episodes, daily pollution cycles, and long-run PM2.5 trends. The long, consistent hourly history also suits model training and dashboards that need continuous pollution data.
