Wetterpark Offenbach, Germany. The Deutscher Wetterdienst (German pronunciation: [ˌdɔʏ̯ʧɐ ˈvɛtɐdiːnst]) or DWD for short, is the German Meteorological Service, based in Offenbach am Main, Germany, which monitors weather and meteorological conditions over Germany and provides weather services for the general public and for nautical, aviation, hydrometeorological or agricultural purposes.
The scale of dBZ values can be seen along the bottom of the image. dBZ is a logarithmic dimensionless technical unit used in radar. It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).

Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
Its major payload is an X-band (3.1 cm) radar sensor, with different modes of operation, which allows it to provide multiple imaging modes for recording images with different swath width, resolution and polarizations, see the figure for more details. In stripmap mode (spatial resolution of 3m), it needs 10 weeks to map global Earth's landmass.
Bayerischer Rundfunk was founded in Munich in 1922 as Deutsche Stunde in Bayern. It aired its first program on 30 March 1924. It aired its first program on 30 March 1924. The first broadcasts consisted mainly of time announcements, news, weather and stock market reports, and music.
A plan position indicator (PPI) is a type of radar display that represents the radar antenna in the center of the display, with the distance from it and height above ground drawn as concentric circles. As the radar antenna rotates, a radial trace on the PPI sweeps in unison with it about the center point. It is the most common type of radar ...
In addition to range, the more common two-dimensional radar provides only azimuth for direction, whereas the 3D radar also provides elevation. Applications include weather monitoring, air defense, and surveillance. The information provided by 3D radar has long been required, particularly for air defence and interception. Interceptors must be ...
Radar geo-warping is the adjustment of geo-referenced radar images and video data to be consistent with a geographical projection.This image warping avoids any restrictions when displaying it together with video from multiple radar sources or with other geographical data including scanned maps and satellite images which may be provided in a particular projection.
