dc.description.abstract | This paper reviews the state of the art of protocols for the measurement of downwelling
irradiance in the context of Fiducial Reference Measurements (FRM) of water reflectance for satellite
validation. The measurement of water reflectance requires the measurement of water-leaving radiance
and downwelling irradiance just above water. For the latter, there are four generic families of method,
using: (1) an above-water upward-pointing irradiance sensor; (2) an above-water downward-pointing
radiance sensor and a reflective plaque; (3) a Sun-pointing radiance sensor (sunphotometer); or (4) an
underwater upward-pointing irradiance sensor deployed at di erent depths. Each method—except
for the fourth, which is considered obsolete for the measurement of above-water downwelling
irradiance—is described generically in the FRM context with reference to the measurement equation,
documented implementations, and the intra-method diversity of deployment platform and practice.
Ideal measurement conditions are stated, practical recommendations are provided on best practice,
and guidelines for estimating the measurement uncertainty are provided for each protocol-related
component of the measurement uncertainty budget. The state of the art for the measurement of
downwelling irradiance is summarized, future perspectives are outlined, and key debates such as the
use of reflectance plaques with calibrated or uncalibrated radiometers are presented. This review
is based on the practice and studies of the aquatic optics community and the validation of water
reflectance, but is also relevant to land radiation monitoring and the validation of satellite-derived
land surface reflectance. | en_US |
