Immersion coefficient for the Marine Optical BuoY (MOBY) radiance collectors



Michael Feinholz, B. Carol Johnson, Kenneth Voss, Mark A. Yarbrough, Stephanie J. Flora


The immersion coefficient accounts for the difference in calibration for a radiometer placed in the air versus water or another medium. The immersion coefficient for the radiance collectors on the Marine Optical BuoY (MOBY) were modeled and measured. The experiment showed that the immersion coefficient for the MOBY radiance collectors agreed with a simple model using only the index of refraction for water and quartz.
