About LiveStation
Real weather data.
Not forecasts.
We believe in measured truth over predicted probability. Every data point on this platform comes from a physical sensor, at a real location, at a precise moment in time.
Our Mission
Understanding the fundamental difference between observation and prediction.
What we provide
- Measured temperature at 14:32:17 UTC
- Actual wind speed from anemometer readings
- Real precipitation amounts from rain gauges
- Precise barometric pressure at station altitude
What we don’t do
- Predicted temperatures for tomorrow
- Probability-based weather models
- City-wide averages or interpolated data
- Weekly outlook or long-term projections
Why does this matter? Forecasts are educated guesses based on models. Observations are facts. When you check our data, you see what the weather is, not what someone thinks it might be.
How It Works
From physical sensor to your screen. The journey of a weather measurement.
Physical Sensor
A calibrated instrument measures atmospheric conditions. Thermometers, anemometers, barometers, rain gauges—each sensor captures one aspect of the weather.
Weather Station
Multiple sensors are combined into a station. The station logs data at regular intervals, typically every 1 to 10 minutes, depending on the network.
Official Network
Stations transmit data to centralized networks like Météo-France's RADOME and ÉTENDU networks. Data is timestamped and stored by the source systems.
Open Data API
Data is published through open-data platforms under licenses like Etalab v2.0, making it accessible with attribution requirements.
LiveStation
We display and process the data to make it easier to explore. The goal is better visualization and navigation around observations.
Data Sources & Transparency
Clear information about where data comes from and how it’s licensed.
France's national meteorological service. A primary source for public observation data used on this site.
Professional-grade automatic weather station network covering metropolitan France.
Extended observation network complementing RADOME with additional stations for geographical coverage.
The open data license allowing reuse with attribution and transparency about updates.
Data integrity commitment
- We do not interpolate or fill gaps with estimates
- Timestamps are preserved as received from source APIs
- Missing data is shown as missing
- Attribution is maintained per license requirements
