The German Weather Service uses EBP's information logistics measurement networks to collect highly dynamic mass data in a highly available system.
The German Weather Service manages almost 200 full-time and approximately 1,000 part-time weather stations. These stations record well over 100 different measurement parameters, some of them to the minute. Data collection, transmission, and provision, as well as the generation of meteorological reports and products, are carried out in a uniform control and processing system. The individual processing steps are distributed across a total of five different main systems, which together ensure routine operation. The systems work largely autonomously and communicate with each other via standardized interfaces.
In addition to the fully automated processing of meteorological measurement data, one of the main functions of the graphical user interface is the manual management of the full-time and part-time measurement network with all associated stations, their administrative and measurement characteristics, their individual configuration settings, and the parameters they measure.
All server systems are subject to internal and external process monitoring. If critical system states are detected, the system automatically initiates appropriate measures to ensure routine operation.
The implementation of a hot standby system allows automatic failover to the secondary instance in the event of serious errors. The secondary instance is physically located at a different site. The primary and secondary instances constantly synchronize their internal process states so that the switchover can be performed within a few milliseconds. This enables an overall availability of 99.95% per quarter to be achieved – while processing five million full-time alarm, measurement, and correction values per day. An on-call team, available around the clock every day, takes care of solving short-term problems and malfunctions.
