Aviation Weather Forecast

In order to carry out the ascent of a drone safely, it is important to check the current weather conditions before the flight. Until now, the weather forecast data could be viewed in the dipul Map Tool. In addition to the Map Tool, the current weather forecast data from the German Weather Service can now be accessed via an API (Application Programming Interface) from dipul. With this new function, the weather forecast data for the next 24 hours can be viewed. The programming interface is designed as an OpenAPI specification and is provided as a REST API for the dipul weather service of German Air Traffic Control (DFS).

The forecast data is generally suitable for UAS operation. 

  • This API enables access to the following weather forecast data:
  • Wind speed and direction for various altitudes
  • QNH (air pressure reduced to sea level according to ICAO standard atmosphere)
  • Temperature for various altitudes
  • Precipitation (rain)
  • Precipitation (snow)
  • Cloud cover (total and for various altitudes) 
  • Relative humidity for various altitudes

with forecasts for up to 24 hours up to 250 metres above ground.

The underlying weather data comes from the high-resolution forecast model ICON-D2 of the German Weather Service (DWD). This model provides a horizontal grid resolution of 2 km and is updated at 3-hourly intervals, allowing for detailed and frequently updated forecasts. Further information on the ICON-D2 weather forecast model is provided by the DWD at (german only):
