# Where does the weather data in the application come from?

In the application it is possible to see what the weather was like in the area of any sensor at any given point in time going all the way back to when it was installed. This includes the amount of precipitation, the temperature, relative humidity and even wind speed and direction.

### Where does the data come from?

Depending on where in the world the sensor is installed, the weather data shown in the application is based on two sources primarily:

- [OpenWeatherMap](https://openweathermap.org/)
- [DMI Open Data](https://opendatadocs.dmi.govcloud.dk/DMIOpenData)

### How reliable is the data?

Weather data always comes with some uncertainty, and evaluating the quality and accuracy should be reserved for meteorology experts hence we encourage you to refer to the quality reports from [OpenWeatherMap](https://openweathermap.org/accuracy-and-quality) and [DMI](https://www.dmi.dk/friedata/guides-til-frie-data/sadan-males-data/) themselves.
