UV Multi-Filter Rotating Shadowband Radiometer (UV-MFR 7): Ultraviolet (UV) Multi-Filter Rotating Shadowband Radiometer (Model UVMFR-7), an instrument that measures global, diffuse, and direct UV solar irradiance at the same time. The recording channels are centered around seven wavelengths (300, 305, 311, 317, 325, 332 and 368 nm) with Nominal Full Width Half Maximum at 2 nm. Measurements are performed every 10 seconds and averaged values are stored every 1 minute. It is designed to operate automatically and autonomously in remote locations with only periodic manual cleaning of the fore optic.
