Abstract

Immersion factors of two TriOS RAMSES ARC series radiance sensors were determined using a method adapted from Zibordi, "Immersion factor of in-water radiance sensors: assessment for a class of radiometers," J. Atmos. Ocean Tech., 23(2), 302 (2006) with two different light sources, LED and tungsten-halogen lamps. The immersion factors determined for the two sensors differ from each other by 0.2% and together they differ by an average 0.3% from Zibordi and Darecki "Immersion factors for the RAMSES series of hyper-spectral underwater radiometers," J. Opt. A: Pure Appl. Opt., 8(3), 252 (2006) determination for a radiance sensor of the same class. The results confirm that the immersion factors for RAMSES radiance sensor are constant enough that measurements from a few samples can be used to represent the entire class. An average immersion factor based on the data measured in this study and in Zibordi and Dareck "Immersion factors for the RAMSES series of hyper-spectral underwater radiometers," J. Opt. A: Pure Appl. Opt., 8(3), 252 (2006) is proposed that has a root-mean-square-difference < 0.2% from 400 nm to 900 nm.
