Cooperation DWD – German Federal States contract, agreement stations-meta-data exchange (name, location, sensors, etc.) DWD: definition of archive, granting of index-numbers for all stations right now via XLS-File planned via Web-Interface ESAU(ascii), BUFR, XML transferfrequence: xx:51 - xx+1:50 DWD ftp-server coordination of data-formats, measuring-frequence, data-transfer, etc. hourly exchange of measured-data Fed.State -> DWD measured-data DWD -> Fed.State measured-data (raw / reviewed), forecast-products (SNOW, RADOLAN, etc.) ESAU(ascii), BUFR, XML data-export via XML stationsinformation exchange Fed.State -> DWD station-modification, disturbances DWD -> Fed.State stations-meta-data-export for each state right now via XLS-File planned via Web-Interface TI21B - 11/2016 – TECO Guangzhou

How it should work in the future .. today future file-based Data-exchange Several Data-Formats via FTP Special File-Distribution-System file-based Data-processing A lot of Data-konversions and distribution of Files before DB-Storage DB-based Data-exchange DB-input-output-Format in XML DB is read-/writable from outside via DWD-API DB-based Data-processing No file-based Data-konversions; needed Files/Reports are created by DB-export.
