MFR-7/UV-MFR-7

The Multi-Filter Rotating Shadowband Radiometer (Model MFR-7, YANKEE) is a field instrument that simultaneously measures global, diffuse, and direct normal components of spectral solar irradiance at six wavelengths: 415, 500, 615, 673, 870, and 940 nm.It can be used to determine the optical depths of water vapor, aerosols, and ozone.

The UV Multi-Filter Rotating Shadowband

Radiometer (Model UVMFR-7, YANKEE) measures global, diffuse and direct narrowband solar radiation at 300, 305, 311, 317, 325, 332, 368 nm with 2 nm FWHM. Direct beam spectral irradiance data provides optical depth information that can be used to track the absolute calibration stability of the instrument.
