UV Radiometry

RSS-1024 / UVRSS-1024 How to purchase this product...

The state-of-the-art Rotating Shadowband Spectroradiometer (RSS) combines a high-performance 1024-pixel CCD spectrograph with an external rotating shadowband similar to that used in our MFR instrument family. It automatically provides instantaneous direct, diffuse, and total irradiance measurements across the majority of the solar spectral range. System optics are thermally stabilized and environmentally sealed to provide excellent long term calibration stability. Instead of using a mechanically scanned diffraction grating, the RSS makes measurements simultaneously across all 1024 channels, and meets the Baseline Solar Radiation Network's requirements for atmospheric turbidity measurements. The shadowband enables the instrument to measure all three components of solar irradiance with one detector. The Model RSS-1024 covers the 360-1100nm visible/NIR range and the Model UVRSS-1024 covers the 292-370nm UV-B and UV-A range. Both systems feature web access to live or stored calibrated spectral irradiance and optical depth data, and use YESDAQ distributed database technology to support networks of remote systems around the globe.

UVMFR-7 How to purchase this product...

The Ultraviolet Multifilter Rotating Shadowband Radiometer (UVMFR) measures total, diffuse, and direct irradiance at seven narrowband wavelengths in the UV-B and UV-A regions. The shadowband enables the instrument to measure all three components of solar irradiance with one detector. The UVMFR-7 system includes the YESDAS-2 datalogger and data analysis software. The MFR-7, a shadowband instrument for the visible/NIR, is also available.

UVB-1, UVA-1 How to purchase this product...

The UVB-1 and UVA-1 Pyranometers measure total irradiance from 280 to 320 nm and 320 to 400 nm, respectively. The instruments produce a high level 0-4 VDC output signal and are thermally stabilized for long term reference-grade measurements. The UVB-1 is field proven in networks throughout the world. Solar dose modeling software, UV-Calc, is included with the instrument. The UVPS power supply (shown) or the YESDAS-2 datalogger are available as accessories.

SPUV-6/10 How to purchase this product...

The SPUV Sun Photometer measures direct normal solar irradiance at up to ten narrowband wavelengths from 300 in the UV-B through  1020 nm in the near-IR, and is the world's most advanced commercial solar sun photometer. Thermally stabilized, environmentally sealed state-of-the-art interference filters, with energy-absorbing visible pre-filters on UV channels provide long term calibration stability. Instead of using a rotating filter wheel, it makes measurements simultaneously across all channels meeting the Baseline Solar Radiation Network's requirements for atmospheric turbidity measurements. A modular mechanical design permits rapid channel service. The SPUV  mounts on most solar trackers (shown here mounted on the ST-1). The SPUV system includes the YESDAS-2 datalogger and works with YESDAS Manager data analysis software.

Atmospheric Radiation Monitoring System How to purchase this product...

The UV/Visible/NIR Atmospheric Radiation Monitoring System (ARMS) consists of the YES MFR-7, UVMFR-7, and UVB-1 pyranometer. This system forms the backbone of the USDA's "UVB Radiation Monitoring Program" run by scientists at Colorado State University (CSU) in Fort Collins, CO. Together these instruments measure direct, diffuse and total spectral irradiance from 300 to 940 nm, as well as broadband UVB and visible irradiance. The network has been providing UV data from nearly 40 sites around North America to the research community for the past seven years. In addition to publishing the data on the web, the group of scientists at CSU who run the network have developed algorithms to extract certain data such as ozone retrievals and have published numerous papers.

The ARMS can optionally be configured with auxiliary sensors such as the TSP-700 pyranometer and/or the TIR-550 IR radiometer to extend global measurements to the Near-IR and IR.
