gironde.qdna.fr: family outings, weather and air quality around Bordeaux
A personal project kept since July 2026 under the name QDNA: a free public-data service for the Gironde and the Landes. It lists family outings around Bordeaux, sorted by age, and combines weather, air quality and pollen for 482 communes.
History. Launched in July 2026 on wildfires, the service was refocused in August on weather and air quality. In October it gained a family-outings agenda, now the first thing on its home page. The figures below come from its about page, re-read on 11 October 2026.
The service in figures
| Name | Gironde aujourd'hui, at gironde.qdna.fr |
|---|---|
| Family outings | events in Bordeaux Métropole and up to 20 km around it, sorted by age from 0 to 17 and by type, re-checked and republished every three days |
| Commune pages | 482 communes of the Gironde and the Landes, each with its own weather and air-quality page |
| Public sources | OpenAgenda (public events), IGN's Géoplateforme (municipality of each venue), ATMO Nouvelle-Aquitaine (ATMO index and official stations), ATMO France (national reference data and pollen scale), the Sensor.Community citizen network and Open-Meteo (observations, hourly forecasts, alerts and Copernicus pollen) |
| Frequency | outings re-checked every three days; air quality and sensors refreshed every 5 minutes; pollen every 3 hours; weather recomputed every hour |
| Status | in production since July 2026, personal non-professional project, served by Cloudflare, no account and no cookie, voluntary accessibility statement published |
What the site does
On the home page, carousels by age band show the next outings: workshops, shows, nature outings, museums or story time. Each entry gives the date, the exact venue, the target age, whether it is free and the official link. That link is re-read before publication, a screenshot of the page is checked and IGN's geocoding confirms the municipality.
For weather and air, the service brings together what public sources publish separately: the regulatory ATMO index, readings from official stations and citizen sensors, weather, alerts and pollen. Every commune has its own page, which compares each pollutant with the WHO 2021 guidelines. The site states that it is not an official service.
How it works
Every three days, an agent orchestrator triggers the agenda pipeline. It collects open events, sorts them by age and type with a language model running locally, then re-reads each official page. Pages that block robots are re-read in a real mobile browser, and cancelled events are dropped.
After each publication, an automated visual check reviews the home page on desktop, tablet and phone, in light and dark themes: number of cards, images, overflow and script errors. New or changed pages are then reported to search engines, and the llms.txt files follow the agenda.
The limits are shown on the site itself: lower accuracy of citizen sensors, publication delay of the ATMO index and uncertainty of two-day forecasts. Pollen is also an estimate drawn from the Copernicus model, rated with Atmo France's scale, not the official index published by the association.
Why this project
gironde.qdna.fr is a personal project, kept on a non-professional basis. It is a testing ground for the methods described in QDNA's analyses: cross-checked open data, verification before publication, content readable by search engines and language models alike. QDNA is not a company and provides no services.
