WaLRUS II Hyperspectral Radiometer Buoy

WaLRUS

WaLRUS II with Es,

and multiple Lu

collectors. 

Water-Leaving Radiance Unison Spectrometer

Self-contained, tethered buoy with multiple hyperspectral radiometers, internal batteries and data logging.  Optimized for the most accurate possible determination of remote-sensing reflectance, water-leaving radiance, and other radiometric measurements at or near the water surface. Operates on the surface, or profiling at depths up to 100 meters.
