Historical PM2.5 (2019)
Description
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.
