Air Quality Measurements (PM 2.5)

Official, stationary, outdoor measurements of particulate matter 2.5 micrometers or less in diameter (PM2.5) reported by government entities or international organizations

  • Source: OpenAQ
OpenAQ is an open-source project to surface live, real-time air quality data from around the world. Its “mission is to enable previously impossible science, impact policy and empower the public to fight air pollution.” This data include air pollutant measurements for PM10, PM2.5, sulfur dioxide (SO₂), carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), and black carbon (BC), from over 5,400 locations in 48 countries as of June 2017. Scientists, researchers, developers, and citizens can use these data to understand how air quality in different locations changes over time. OpenAQ has 5 criteria for including data sources in its platform: 1) Data must represent one of these pollutant types: PM10, PM2.5, SO₂, CO, NO₂, O₃, or BC; 2) data must be from an official-level stationary, outdoor air quality source, defined as data produced by a government entity or international organization; 3) data must be "raw" and reported in physical concentrations on their originating site; 4) data must be at the "station-level," not aggregated into a higher (e.g., city) level; 5) data must be from measurements averag...
