Description:

This data contains past 24 hours pollutant concentration in micrograms per cubic meter of air. The information is collected at various Air Quality Monitoring Stations where NO2 (nitrogen dioxide), O3 (ozone), SO2 (sulphur dioxide), CO (carbon monoxide), PM10 (respirable suspended particulates), and PM2.5 (fine suspended particulates) data is recorded at 60-minute intervals. Please note that the Air Quality Monitoring Station locations displayed on the map are approximate only. The source data is converted to Esri File Geodatabase format for sharing and reference purpose.
