Weather radar
Interesting facts about the weather radar
Since summer 2019, the Institute of Geography and Spatial Research (CC-MoRe research group) has been operating a dual-polarized X-band Doppler weather radar from Furuno to investigate the influence of climate change on precipitation in Graz and the surrounding area.
A significant advantage over precipitation measurements at individual observation sites is that a weather radar provides spatially and temporally high-resolution and area-wide data.
In addition, the radar data should in future make a valuable contribution to the early detection of extreme weather situations and thus reduce economic damage due to increasing severe weather events.
There are two mobile phone masts in the immediate vicinity of the weather radar (south-east and south-west); the radar does not measure any signal in this area.
The visible ring around the radar is caused by different radar-specific sensitivities for measurements in the near and far range. Due to the higher sensitivity of the modulated pulse for measurements in the far range, a visible ring is created at the transition between unmodulated and modulated pulse (at a distance of approx. 8 km), particularly in the case of weak precipitation.
