The German Meteorological Service (DWD)
operates some 160 main MEteoDEA E100 weather stations and a
further 800 AMDA III secondary weather stations. It is important
that the registration, transfer and preparation of data, and also
the generation of reports and products takes place under a
uniform control and processing system with a standard user
interface. To meet this requirement, Ernst Basler + Partner has
developed ILM information logistics for measurement
networks.
This consists of a distributed system which administers the DWD
weather stations, receives the alarm reports, and pre-processes
measurement data, generates reports such as SYNOP (FM 12) or BUFR
(FM 94) and passes these on, or stores them in a suitable form.
The measurement data from about 1000 meteorological stations is
processed within only a few minutes, so that the international
distribution of meteorological measurements to the WMO can take
place punctually.
Software systems which have already been used successfully have
been integrated in the communication flow. The newly developed
sub-systems are largely autonomous and because they are not
dependent on the hardware and platform they can easily be
integrated in other architectures.
In order to improve failure prevention, many of the systems are
operated in duplicate at a second location. These secondary
systems are synchronised with the primary set-up, and if there is
a disturbance in one of the primary systems, the processing tasks
are taken on at the secondary location without delay. In this way
an overall availability of 99.95% per quarter can be
achieved.
