Definitions for "WRR"
The World Radiometric Reference, which provides the basis for all measurements by radiometers in the world. Every five years, many of the best absolute cavity radiometers undergo an intercomparison at PMOD/WRC (Davos, Switzerland). The most stable, accurate, and precise instruments provide the World Radiometric Reference for the coming years. Any credible radiometer measurement must be traceable to the WRR.
