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. The data was provided by the Environmental Protection Department of The Government of the Hong Kong Special Administrative Region. It was compiled in XML file format when originally downloaded via DATA.GOV.HK. For display on Esri ArcGIS Online, the information was subsequently populated to a feature layer containing the locations of the Air Quality Monitoring Stations. Please note that the Air Quality Monitoring Station locations displayed on the map are approximate only.
