C-OPS
Compact-Optical Profiling System

The Compact-Optical Profiling System (C-OPS) is an in situ water-based radiometer system developed at Biospherical Instruments. It measures vertical profiles of ocean radiance and irradiance for depths of 150 to 300 m. It consists of two radiometers operating across the 250-1650 nm wavelength range. C-OPS has a typical sampling rate of 125 Hz and has a vertical resolution of less than 1 cm. It also consists of ancillary sensors that provide measurements of water temperature, pressure, and humidity.
