| Zusammenfassung |
| Research in recent years has shown that data from commercial microwave link networks can
provide very valuable precipitation information. Since these networks comprise the
backbone of the cell phone network, they provide countrywide coverage. However
acquiring the necessary data from the network operators is still difficult. Data is
usually made available for researchers with a large time delay and often at irregular
basis. This of course hinders the exploitation of commercial microwave link data
in operational applications like QPE forecasts running at national meteorological
services.
To overcome this, we have developed a custom software in joint cooperation with
our industry partner Ericsson. The software is installed on a dedicated server at
Ericsson and is capable of acquiring data from the countrywide microwave link
network in Germany. In its current first operational testing phase, data from several
hundred microwave links in southern Germany is recorded. All data is instantaneously
sent to our server where it is stored and organized in an emerging database. Time
resolution for the Ericsson data is one minute. The custom acquisition software,
however, is capable of processing higher sampling rates. Additionally we acquire
and manage 1 Hz data from four microwave links operated by the skiing resort in
Garmisch-Partenkirchen.
We will present the concept of the data acquisition and show details of the custom-built
software. Additionally we will showcase the accessibility and basic processing of real time
microwave link data via our database web frontend. |
