Weather radar (GOP-2)

Weather radars measure the range resolved radar reflectivity factor (Z) in dBZ from which the surface rain rate (RR) is commonly derived using Z-RR relations of the form Z=a·RR^b. In addition Doppler radars provide the radial velocity (v) and sometimes also the spectral width (σ). Polarimetric radars can also observe the differential reflectivity (ZDR) and the linear depolarization ration (LDR).

For GOP operational radar products by the DWD network and original 3-D radar measurements will be made available. Research radars operated by universities, research centers and DWD will also be included. The PQP project VERIPREG (Paulat et al. 2005) will produce hourly precipitation maps from a combination of radar (composite of precipitation scans) and in situ rain gauge data. The PQP project QUEST will use the 3D radar reflectivities to evaluate the forecasted hydrometeor distributions via forward simulation by a polarimetric radar operator.
