dc.description.abstract | The absorption coefficient of chromophoric dissolved organic matter (CDOM) at 355 nm has been retrieved
from airborne laser-induced and water Raman-normalized CDOM fluorescence. Four combined airborne
and ship field experiments have demonstrated that (1) the airborne CDOM fluorescence-to--water
Raman ratio is linearly related to concurrent quinine-sulfate-standardized CDOM shipboard fluorescence
measurements over a wide range of water masses (coastal to blue water); (2) the vicarious calibration
of the airborne fluorosensor in units traceable to a fluorescence standard can be established and then
maintained over an extended time period by tungsten lamp calibration; (3) the vicariously calibrated
airborne CDOM fluorescence-to-water Raman ratio can be directly applied to previously developed
shipboard fluorescence-to-absorption algorithms to retrieve CDOM absorption; and (4) the retrieval is not
significantly affected by long-path multiple scattering, differences in attenuation at the excitation and
emission wavelengths, or measurement in the 180° backscatter configuration. Airborne CDOM
absorption measurements will find immediate application to (a) forward and inverse modeling of oceanic
water-leaving radiance and (b) validation of satellite-retrieved products such as CDOM absorption. | en_US |
dc.description.sponsorship | We thank Diane Wickland and Frank Muller-
Karger of NASAHeadquarters for their support of the
flight programs and Ken Carder (University of South
Florida) for the invitation to participate in the Tampa
Bay Experiment. Christina Fair (Scripps Institution
of Oceanography) collected the samples from the Gulf
of Mexico. Ship support for the Monterey Bay cruises
was provided by the Monterey Bay Aquarium Research
Institute (Peter Brewer), and the Middle Atlantic
Bight cruises were supported by the U.S. Office of
Naval Research (N. V. Blough, Chief Scientist).
Additional support was provided by the NASA EOS
Interdisciplinary Program. This work was done while
A. Vodacek was a National Research Council resident
research associate at NASA. | en_US |
