About

The European Environment Agency runs the Air Quality Download Service for measurement time series that member and cooperating countries report under the Air Quality Directive. The service holds validated data (E1a) from 2013 onward, up-to-date data (E2a) transmitted continuously, and historical Airbase data from 2002 to 2012. Each Parquet file is one complete time series at a sampling point, named by its localId.

Through Fibric an operator pulls the series for the countries, cities, and pollutants you name, at hourly or daily aggregation, and sets them beside what your own building sensors report.

This is a reference listing. It documents what Fibric would read from EEA Air Quality Download Service and what it could propose, based on the publisher's published interfaces. Fibric builds it under a managed deployment when you request it; selecting it here installs nothing.

Inputs

  • Countries and cities available for filtering through GET /Country and POST /City
  • Pollutant notations and Eionet vocabulary URIs through GET /Pollutant
  • Zipped Parquet time series through POST /ParquetFile, filtered by countries, cities, pollutants, dataset, and date range
  • Background downloads through POST /ParquetFile/async and file listings through POST /ParquetFile/urls
  • File counts and sizes for a filter through POST /DownloadSummary before you fetch
  • Hourly, daily, or variable-interval series selected with aggregationType
  • Station data as WMS, WFS, and ArcGIS REST layers from air.discomap.eea.europa.eu

Proposed actions

Read-only. This feed informs operators; it changes nothing.

Proposed actions are target capabilities. Every action runs propose-first and needs a validated deployment and the appropriate permissions.

What you can build

  • Benchmark outdoor air across European sites

    Pull validated E1a series for the cities where you operate and compare PM10, NO2, and O3 exposure site by site. The operator drafts the comparison for your review.

    With Site Benchmark

  • Check outside air before the economizer opens

    Read up-to-date E2a readings near a building and flag hours when outdoor PM2.5 makes free cooling a poor trade. The proposal names the station and the hour.

    With Economizer Check, Indoor Air

  • Keep a record for environmental reporting

    Attach the EEA sampling point, dataset, and date range behind each figure you cite so the source can be reopened later.

    With Compliance Evidence

Requirements

  • A dataset number on each request: 1 for up-to-date E2a, 2 for validated E1a, 3 for historical Airbase
  • Country codes, city names, or pollutant notations for the filter you want
  • Parquet tooling on your side; files are zipped Parquet, not CSV or JSON
  • Storage for large pulls; a request over 600 MB returns status 206 and a partial file
Authentication
No key. Each download request accepts an optional email field so the EEA can contact you if a problem is detected.

Limits

  • Downloads are capped at 600 MB per request; use ParquetFile/urls and fetch files one by one above that
  • E1a validated data arrives once a year, reported by countries by 30 September for the previous year
  • Hourly and variable series are stamped in UTC+1; daily values keep the timezone each country reported
  • ParquetFile/urls ignores date and aggregation filters and returns whole-series file locations

Questions and answers

Which dataset number should you use for current readings?
Dataset 1, up-to-date data (E2a). The EEA labels it unverified and transmits it continuously. Dataset 2 is validated E1a data from 2013, reported once a year. Dataset 3 is historical Airbase data from 2002 to 2012. Dataset 5 is gap-filled E2a.
Does the service return JSON or CSV?
No. Time series come as zipped Parquet files, one per sampling point. Lookup endpoints for countries, cities, and pollutants return JSON. ParquetFile/urls returns a CSV of file URLs rather than the data itself.
What licence covers the data?
The EEA publishes the dataset under CC-BY 4.0 with the European Environment Agency as copyright holder. The catalogue record states no limitations to public access.
