Historical 1-hr PM2.5

Description

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.
