Share 96 20:17 Air Quality Historical Data Platform Institution & University Registration Selecteer een taal▼ Share: aqicn.org/data-platform/register/ Special COVID-19 If you are looking for a data set covering many cities/countries during the COVID-19 period (January 2020 until now), go to the COVID-19 data page. Can you find more than 100M bytes of CSV data-set covering more than 380 cities. -- Since the beginning, the World Air Quality Index (WAQI) project team has always been keen on providing a transparent Air Quality Information to the world citizens. The WAQI project has also always been keen on providing historical Air Quality Data to relevant institutions and organizations working in the area of environmental awareness, air quality monitoring, as well as health and epidemiological studies. Here are few of our partners and colleagues to which we have been providing historical air quality data information: United Framework In order to make the historical Air Quality Data dissemination even more relevant, the World Air Quality Index team has been investigating with the most relevant international institutions the possibility to setup an open data framework. Here are fews of the institutions we have engaged: WHO - World Health Organization UNEP - United Nation Environmental Program UNIDO - United Nation Industrial Development Organization WMO - World Meteorological Organization GEO - Group on Earth Observations WRI - World Resource Institute CCA - Climate & Clean Air Coalition UNFCCC - United Nations Framework Convention on Climate Change The open data framework objective is to provide unlimited and free access the world historical and real-time Air Quality data from the 100+ countries covered on aqicn.org Everyone - both institutions as well as citizens - agrees that this is not only a good idea, but that it should *just* happen. Free Downloadable Database Database Download The daily average air quality data for all of the stations can be downloaded freely from the form below. Note that all the figures are converted to AQI using the US EPA standard: i.e. we do not publish the raw concentrations, but only the AQI. Enter the name of a station, eg Beijing Or select on the station your previously visited or nearest stations: Wuhan北京BrusselsAarschotCorroy-le-grandVilvoordeNeder-over-heembeek 0~25 25~50 50~75 75~100 100~125 125~150 150~175 175~200 200~300 300~400 >400 -- Notes: If you want to download multiple stations at once, covering the COVID-19 period, go to the COVID-19 data page instead. You can find a ~28MB downloadable data-set covering more than 380 cities worldwide. The Air Quality data is currently only available for the past 7 years, from 2014 until now. If you need data before this period, we recommend to either contact the originating EPA, or consider using estimates based on remote sensing data. You can for instance check the catalog from the AERIS/ICARE project, which is archiving satellite data since 2000. In the above data, we publish the "Individual pollutant" Air Quality index. For instance, if you check the figures for PM2.5, they correspond to the PM2.5 individual AQI (noted as AQIPM2.5). If you want to calculate the overall AQI, aka composite AQI, you need to take the maximum of all individual AQI: AQI = max( AQIPM2.5, AQIPM10, AQIO3, ...) Last if you need the real-time data instead, try the API page. It's free too! Inquiry & Registration If the above data does not work for you, and you are from an international institution, organization or university you can register your interest with the form below. Note that this registration is only at intent level, for us to consolidate the list of all interested parties, and does not bound you, nor the world air quality index project, to any obligations. Institution & University Registration - subscription form Your information Enter your name - eg "John Doe" Enter your email address - eg "john.doe@mail.com" Enter your organization - eg "Harvard Business School" Enter your position - eg "Student, Researcher, Head" Data information Data Period - eg "June 2018" to "August 2018" Start date Stop date Data Frequency Daily Data Units Raw Concentration Enter the name of the stations you need the data for - eg "Beijing" Name of a station, eg Beijing Or add one of the previously visited station Wuhan北京 Tell us a bit more Write few words about your request - eg: "I would like to get the daily max AQI for Berlin for Winter 2014", "I would like to know the hourly concentration of SO2 for Civil Lines in Delhi on June 18th 2015", "I would like to support your project and give you hand", .. Contributing or Supporting this Project ✋The World Air Quality project might look like one of those big projects coming from big organizations... but it is actually just a small, but lean, team behind it. Despite its expensive outreach, the project has never received any financial support from any of NGO nor from any government🌸 The project income comes online advertising, but it is just enough to pay the cloud infrastructure. So, yes, all contributors are having a real job at the same time🙏 Yet, rather than asking for financial support, we prefer asking for contributors who can help with their time. Check the contribute page for more info. ❤️❤️❤️ If you do not have time to contribute, but still would like to help and support our project, what about getting one of our cool GAIA air quality monitoring station? ☀️💨👌 🌏🌎🌍 Data Credits The open data framework would not be possible without the work from the worldwide EPA, which should get the credits for their monitoring programs. About the Air Quality and Pollution Measurement: About the Air Quality Levels AQI Air Pollution Level Health Implications Cautionary Statement (for PM2.5) 0 - 50 Good Air quality is considered satisfactory, and air pollution poses little or no risk None 51 -100 Moderate Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion. 101-150 Unhealthy for Sensitive Groups Members of sensitive groups may experience health effects. The general public is not likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion. 151-200 Unhealthy Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion 201-300 Very Unhealthy Health warnings of emergency conditions. The entire population is more likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion. 300+ Hazardous Health alert: everyone may experience more serious health effects Everyone should avoid all outdoor exertion To know more about Air Quality and Pollution, check the wikipedia Air Quality topic or the airnow guide to Air Quality and Your Health.
