National Environment Agency (NEA) publishes year-by-year CSV files of historical fine particulate matter (PM2.5) for Singapore from 2016 through 2024. Timestamps use Singapore Time in ISO 8601. Analysts studying haze episodes, long-term air quality trends, or public-health exposure can download separate annual datasets. Official metadata warns that records may be incomplete and are not quality-controlled like certified climate products. For authoritative climate reporting, NEA directs users to its climate sales contact.
Official description
Historical PM2.5 for Singapore. All timestamps are provided in Singapore Time (SGT), formatted in ISO 8601.

National Environment Agency CSV of historical PM2.5 readings across Singapore for the full 2024 calendar year. Records contain SGT timestamps, update times, region identifiers and coordinates, and regional one-hour PM2.5 values. Environmental and public-health researchers can reconstruct spatial and temporal air-quality patterns or haze episodes, while accounting for possible missing records and the absence of official climate-data quality control.
National Environment Agency historical PM2.5 fine particulate matter readings for Singapore across 2023, with ISO 8601 timestamps in Singapore Time. Columns cover date, timestamp, region and region ID, monitoring-station longitude and latitude, and one-hourly PM2.5 values for the five air-quality regions. Environmental researchers and air-quality analysts reconstruct 2023 pollution episodes; the file may contain gaps and is not quality-controlled climate data.
National Environment Agency historical PM2.5 fine particulate matter readings for Singapore across 2022, with ISO 8601 timestamps in Singapore Time. Columns cover date, timestamp, region and region ID, monitoring-station longitude and latitude, and one-hourly PM2.5 values for the five air-quality regions. Environmental researchers and air-quality analysts reconstruct 2022 pollution episodes; the file may contain gaps and is not quality-controlled climate data.
National Environment Agency historical PM2.5 fine particulate matter readings for Singapore across 2021, with ISO 8601 timestamps in Singapore Time. Columns cover date, timestamp, region and region ID, monitoring-station longitude and latitude, and one-hourly PM2.5 values for the five air-quality regions. Environmental researchers and air-quality analysts reconstruct 2021 pollution episodes; the file may contain gaps and is not quality-controlled climate data.
National Environment Agency historical PM2.5 fine particulate matter readings for Singapore across 2020, with ISO 8601 timestamps in Singapore Time. Columns cover date, timestamp, region and region ID, monitoring-station longitude and latitude, and one-hourly PM2.5 values for the five air-quality regions. Environmental researchers and air-quality analysts reconstruct 2020 haze and pollution episodes; the file may contain gaps and is not quality-controlled climate data.
National Environment Agency CSV of hourly PM2.5 readings across Singapore for calendar year 2019. Each record carries a date, a reading timestamp and an update timestamp in Singapore Time formatted to ISO 8601, the reporting region and its region id, the region's longitude and latitude, and the one-hourly PM2.5 value. Because readings are tagged by region and coordinates, users can map fine-particulate levels across the island and build hourly time series for haze episodes or seasonal comparisons. Air-quality researchers and public-health analysts use it for exposure and trend work, noting that records may be missing and have not undergone quality control.
National Environment Agency CSV of historical hourly PM2.5 readings across Singapore regions for calendar year 2018. Columns include date, timestamps (SGT, ISO 8601), region, coordinates, and one-hourly PM2.5. Air-quality researchers analyse spatial and temporal fine-particle patterns; the series may have gaps and is not quality-controlled climate data.
National Environment Agency CSV of one-hourly PM2.5 readings for Singapore across 2017, with date, timestamp, update timestamp, region name and id, region longitude and latitude, and the PM2.5 value. Timestamps are in Singapore Time formatted to ISO 8601. Air quality researchers use the year-long archive for exposure and haze episode analysis, noting that records may be missing and have not undergone climate-grade quality control.
This dataset contains historical hourly PM2.5 readings for Singapore from 10 February through 31 December 2016. Records include date and SGT timestamps, update time, region and region identifier, location coordinates, and one-hour PM2.5 values. It can support retrospective analysis of fine-particle pollution across regions and time, but the publisher warns that records may be missing and have not undergone the quality-control procedures applied to official climate data.
