The data warehouse is the central measurement data platform of MeteoSwiss. This is where the vast range of data from monitoring stations and many other sources is consolidated and processed according to standardised rules. The central database provides the foundation for the forecasts and analyses of MeteoSwiss. It is also available to external users.
As the national weather service, MeteoSwiss is entrusted with the recording, storage and management of wide-ranging meteorological and climatological data. Ground-based stations, weather radars and numerous other sources provide millions of measurement values in various formats each and every day. In order to manage this wealth of data, MeteoSwiss operates a data warehouse system. This includes a central database known as the data warehouse (DWH). The system also has a central metadata repository which contains all information on the description of the actual measured values and the management of the respective processes. The system also provides the tools for the preparation and processing (aggregation, quality assurance and amendment) of meteorological and climatological data as well as various other applications.
The DWH system provides quick, customised data access, both to current data and historical data series. MeteoSwiss produces the majority of its meteorological and climatological products – from its weather forecasts to its detailed climate analyses – using data from the DWH. External users can also access the data.
These measurement data are also available to external users via a variety of purchasing options. Please contact Customer Service for more information.
The data warehouse is made up of a four-layer architecture:
