| Zusammenfassung |
| The Feldbach region in southeast Austria, characteristic for experiencing a rich variety of
weather and climate patterns, has been selected as the focus area for a pioneering
weather and climate observation network at very high resolution: The WegenerNet
comprises 151 meteorological stations measuring temperature, precipitation, and other
parameters, in a tightly spaced grid within an area of about 20 km x 15 km centered
near the city of Feldbach (46.93°N, 15.90°E). With its stations about every 2 km2,
each with 5-min time sampling, the network provides regular measurements since
January 2007. Quality-controlled station time series and gridded field data (spacing
200Âm x 200Âm) are available in near-real time (data latency less than 1–2Âh)
for visualization and download via a data portal (www.wegenernet.org). Detailed
information is available in the recent description by Kirchengast et al.Â(2014) and via
www.wegcenter.at/wegenernet.
The network is set to serve as a long-term monitoring and validation facility for weather
and climate research and applications. Uses include validation of nonhydrostatic models
operated at 1-km-scale resolution and of statistical downscaling techniques (in particular for
precipitation), validation of radar and satellite data, study of orography–climate relationships,
and many others.
The poster gives a brief introduction to the WegenerNet design and setup, its processing
system and its data products, with a focus on recent developments. The latter include
calibration of weather radar data (by calculating the reflectivity–rain rate transfer function of
each single radar image), derivation of soil moisture from matric potential data (for inclusion
in the International Soil Moisture Network), and the development of a versatile
semi-automatic maintenance system. Also some example results are shown, including
extreme weather events and climate variability over the 8-yr period from 2007 to
2014.
