Micro Rain Radar (MRR-PRO)

The Micro Rain Radar (MRR-PRO) instrument is made by Metek.

Product Description The newly developed hardware of the MRR-PRO combines the unique Micro Rain Radar technique of the MRR-2 and a high performance processing unit which significantly improves all operating parameters. The system allows precise measurements of the Doppler spectra caused by hydrometeors and yields the rain rate, liquid water content and drop size distribution for the liquid phase. All computations including automatic melting zone detection are integrated in the outdoor electronics. The system has been evolved to be a powerful stand-alone profiler for investigations of precipitation and cloud dynamics with very low installation and logistics effort.
