Deutscher Wetterdienst Open Data Server

The Deutscher Wetterdienst (DWD) Open Data Server is the official open data portal of Germany's national meteorological service. Established under a legal mandate from the German Weather Service Act, its primary purpose is to provide free public access to a vast and diverse collection of weather, climate, and environmental spatial data. The repository serves a wide range of users, from researchers and developers to businesses and the general public, by offering data essential for applications in science, technology, and public information. The scope of data is comprehensive and includes: Weather Data: Numerical model forecasts, radar data, and current measurements/observations. Climate Data: A large archive of historical and processed climate data, accessible via the integrated Climate Data Center (CDC) subtree. Specialized Formats: Many datasets are also available through OGC-compatible web services (WMS, WFS) for integration into Geographic Information Systems (GIS). The platform operates on the principle of free provision, though it notes that service and availability levels for the open server are not guaranteed. For critical business or operational processes requiring higher data integrity, dedicated service agreements are available. The repository is actively maintained, with news feeds and change logs to inform users of updates and extensions to the data offerings.
