Ultraviolet Multifilter Rotating Shadowband Radiometer UVMFR-7
The Model UVMFR-7 Ultraviolet Multi-Filter Rotating Shadowband Radiometer is an instrument that measures diffuse and total global irradiance, and computes direct irradiance at four or seven narrow-bandwidth wavelengths in the UV-B and UV-A regions. It extends the YES shadowband instrument family into the UV-B, providing the atmospheric scientist with a low-cost precision tool for measuring narrowband UV-B total, direct, and diffuse spectral irradiance. Real-time UVMFR-7 data is available at sites across the US by browsing http://uvb.nrel.colo state.edu The UVMFR-7 provides spectral irradiance data with stability equal to that of spectroradiometers but at a fraction of the cost. In addition, unlike most global spectroradiometers that only provide total horizontal irradiance, the UVMFR-7 makes diffuse, and direct normal measurements. Direct beam spectral irradiance data provides optical depth information that can be used to track the absolute calibration stability of the instrument. Most UV-B field spectroradiometers for making narrowband irradiance measurements demand constant attention by highly skilled personnel. The UVMFR-7 is designed to operate automatically and autonomously in remote locations with only periodic manual cleaning of the fore optic. A unique optical design coupled with the flexible and powerful YESDAS-2 data acquisition and control system, gives the instrument high performance at a modest price.
