The WegenerNet climate station network in the Feldbach region (southeast Styria/Austria) consists of more than 150 climate stations that have been measuring small-scale weather and climate developments with unprecedented levels of accuracy since 2007. In an area of ​​around 22 km × 16 km (average station density: one station per ∼2 km²), parameters such as air temperature, relative humidity, precipitation and, at selected stations, wind speed and direction, as well as soil moisture are recorded with 5-minute resolution.

In 2020, the 2D ground station network was expanded into a 3D open-air laboratory for climate research with very high spatial and temporal resolution. The measuring devices used for this consist of
1. A polarimetric X-band Doppler weather radar for recording precipitation data in the troposphere above the ground station network.
2. A troposphere profiling radiometer (combined microwave/infrared radiometer) for measuring temperature and humidity profiles, as well as liquid water and water vapor content in the troposphere over the WegenerNet area.
3. An infrared radiometer for precise, spatially gridded measurement of the height of the cloud base and the 3D cloud structure over the WegenerNet area.
4. A GNSS ground station network called GNSS-StarNet, for high-resolution measurement of the water vapor content and precipitable precipitation water over the WegenerNet area. The network consists of six GNSS stations, which are arranged in a star shape.

In addition, the WegenerNet climate station network in the Gesäuse region (formerly "Johnsbachtal") in the Ennstal/Gesäuse National Park area is a smaller "sister network" of the Feldbach region and represents a supplement in the Alpine region. The network has seventeen meteorological and two hydrographic stations, which have been gradually built since 2007. The stations are located at altitudes from below 700 m to over 2100 m and measure parameters such as temperature, humidity, precipitation, radiation and wind with a 10-minute resolution.
