===== Principle ===== | ===== Principle ===== | ||
+ | The Multifilter Rotating Shadowband Radiometer (MFRSR) is a passive instrument that measures global and diffuse components of solar irradiance at one broadband channel and at six narrowband channels, i. e. at 415, 500, 615, 673, 870, and 940 nm. Direct irradiance is subsequently calculated from the diffuse and global measured components. Each MFRSR measurement sequence includes measurements at four different shadowband positions: 1) at nadir (home position), 2) at the first side-band position, 3) sun-blocked, | ||
