Publikováno v: Journal of atmospheric and oceanic technology. 34(7)

The upwelling radiance attenuation coefficient KLu in the upper 10 m of the water column can be significantly influenced by inelastic scattering processes and thus will vary even with homogeneous water properties. The Marine Optical Buoy (MOBY), the

Immersion Coefficient for the Marine Optical Buoy (MOBY) Radiance Collectors

Autor: B. Carol Johnson, Stephanie J. Flora, Kenneth J. Voss, M Feinholz, Mark A. Yarbrough

The immersion coefficient accounts for the difference in responsivity for a radiometer placed in the air versus water or another medium. In this study, the immersion coefficients for the radiance collectors on the Marine Optical Buoy (MOBY) were mode

Publikováno v: Journal of Atmospheric and Oceanic Technology. 20:383-391

The Marine Optical System (MOS) is a dual charge-coupled device (CCD)-based spectrograph system developed for in-water measurements of downwelling solar irradiance Ed and upwelling radiance Lu. These measurements are currently used in the calibration

Stray-light correction algorithm for spectrographs

Autor: Steven W. Brown, Dennis K. Clark, M Feinholz, Stephanie J. Flora, Mark A. Yarbrough, Keith R. Lykke, B. Carol Johnson

Publikováno v: Metrologia. 40:S81-S84

In this paper, we describe an algorithm to correct a spectrograph's response for stray light. Two recursion relations are developed:?one to correct the system response when measuring broad-band calibration sources, and a second to correct the respons

Publikováno v: SPIE Proceedings.

For the past decade, the Marine Optical Buoy (MOBY), a radiometric buoy stationed in the waters off Lanai, Hawaii, has been the primary in-water oceanic observatory for the vicarious calibration of U. S. satellite ocean color sensors, including the S

Publikováno v: SPIE Proceedings.

Determination of the water-leaving spectral radiance using in-water instrumentation requires measurements of the upwelling spectral radiance (Lu) at several depths. If these measurements are separated in time, changes in the measurement conditions re
