Air Pollutant - Particulate Matter PM10 (24-hr Mean -99th Percentile)
NEA air quality open data in this collection reports annual 24-hour mean PM10 at the 99th percentile from 2000 through 2022, aligned with WHO Air Quality Guidelines (2005 global update). The CSV Air Pollutant - Particulate Matter PM10 (24-hr Mean -99th Percentile) supports long-term particulate trend analysis and policy evaluation against international reference levels. Environmental health researchers can compare Singapore’s PM10 extremes across years while noting the percentile metric rather than daily PSI readings. Annual frequency matches NEA’s published environmental statistics series.
Official description
Annual 24-hr means (99th percentile) for PM10 (µg/m3) are based on WHO Air Quality Guidelines (global update 2005).
National Environment Agency annual CSV of Singapore’s PM10 24-hour mean at the 99th percentile from 2000 through 2025. The series tracks high-end particulate pollution exposure used in air-quality reporting. Environmental health researchers and policy analysts monitor long-run PM10 peak-day intensity against haze and traffic emission trends.
