This site shows air quality based on readings from Open Source sensors from Luftdaten.
You can compare readings from differet sensors/times using the drop down boxes in the pages with visualisations.
The data for this site come from the Luftdaten data archive.
About Particulates (from Wikipedia)
Particulate matter (PM) is microscopic solid or liquid matter suspended in the atmosphere of Earth. Sources of particulate matter can be natural or anthropogenic. They have impacts on climate and precipitation that adversely affect human health.
- The IARC and WHO designate airborne particulates a Group 1 carcinogen.
In 2013, a study involving 312,944 people in nine
European countries revealed that:
- there was no safe level of particulates
- for every increase of 10 μg/m3 in PM10, the lung cancer rate rose 22%
- the smaller PM2.5 were particularly deadly, with a 36% increase in lung cancer per 10 μg/m3 as it can penetrate deeper into the lungs.
- Worldwide exposure to PM2.5 contributed to 4.1 million deaths from heart disease and stroke, lung cancer, chronic lung disease, and respiratory infections in 2016.
- Overall, ambient particulate matter ranks as the sixth leading risk factor for premature death globally.

Shows air quality by day of the week and time of day. Each segment shows average (mean) air quality particulate readings for a one hour block. Red indicates the highest air pollution levels.
Shows air quality particulate readings as 24 hour means. Each point shows the average air quality reading for the 24 hours preceding it. This lets us measure the air quality against air quality indexes.
