It was designed and constructed by the P. P. Shirshov Institute of Oceanology of the Russian Acadamy of Science (SIO RAS). Upwelling radiance is measured just beneath the sea surface and downwelling irradiance just above the sea surface at a distance approximately 50 m from the ship. It measures upwelling radiance and downwelling irradiance in the spectral range 390-700 nm with a spectral resolution of 2.5 nm. It has a radiometric accuracy of 5 percent."@en . .
