CAROb shadowband radiometer

The multi-filter rotating shadowband radiometer (MFRSR) measures the direct normal, diffuse horizontal and total horizontal solar irradiances at six different wavelengths: 415, 500, 615, 673, 870, and 940 nm. Wavelength-dependent aerosol optical depths, ozone column, and the water vapor path can be retrieved from these measurements. The CAROb shadowband radiometer has been operating since May 20, 2013.
