91. Radiometric Characterization and Calibration of the Marine Optical System (MOS) for the Marine Optical Buoy (MOBY) Project
Published: 10/1/2000
Authors: C Habauzit, Steven W Brown, Keith R Lykke, Bettye C Johnson, M Yarbrough, M Feinholz, D K Clark
Abstract: The scientific objective of the Marine Optical Buoy (MOBY) project is to measure the downwelling spectral irradiance, E^dd^, and the upwelling spectral radiance, L^du^, at various depths in the ocean. From these measurements, other quantities can be ...
