About PiSpace Air

What you can look up

Search for a city to see available outdoor air quality information, forecasts and nearby monitoring stations. Check the source and measurement or forecast time on each result. Use Compare to inspect the same pollutant across up to three places.

The site brings together public observations and atmospheric model output. Instrument coverage is strongest in the European sources used by the service. The broader forecast catalogue gives an area estimate for supported places.

How the service works

PiSpace Air is noncommercial and available without a visitor account. The public pages cite their data providers and show gaps when suitable information is unavailable. The source agencies and national services remain the best place to check official notices and long-term assessments.

Editorial policy

Guides cite the agency or dataset behind technical claims. Worked examples use illustrative numbers. City and station pages label the data source, time, units and coverage. Forecasts and observations are presented separately so readers can tell which values come from a model and which come from an instrument.

We check reported problems against the cited source and update the affected text or attribution when a correction is needed. To report an error, use the Contact page when an address is listed. Include the page link and the reading, time or paragraph in question.
