Atmospheric Radiometers

Atmospheric radiometers are used above water, typically to measure downwelling irradiance or spectral irradiance.

The GUV series was developed to measure UV and visible radiation at several wavelengths from 305 nm to 700 nm. The latest GUV, the GUVis-3511, covers the wavelength range from 305 to 1,640 nm and is available with up to 19 channels. This instrument can be equipped with a shadowband to derive the direct solar irradiance and related data products such as aerosol optical depth. GUV instruments are deployed worldwide.

The C-OPS Surface Irradiance Sensors were primarily developed for use with marine profiling systems, but can also be used for atmospheric measurements. These instruments are not temperature stabilized and are therefore less suitable for long-term monitoring activities than GUV radiometers.

Although not commercially available, the Scanning UV spectroradiometer (SUV-150B) is a double-monochromator based scanning UV instrument measuring global spectral irradiance at a spectral resolution of 0.7 nm. It is a fully automated, all weather system designed to be installed through the roof of a facility. An SUV-150B was part of the UV Monitoring Network operated by Biospherical Instruments that was installed at the top of the Greenland icesheet.
