Zusammenfassung |
Time series of inherent optical properties (IOPs) derived from SeaWiFS and
MODIS are compared for the Adriatic Sea. The IOPs are outputs of the
Quasi-Analytical Algorithm and include total absorption a, phytoplankton
absorption aph, absorption associated with colored detrital material
(CDM) acdm, and particle backscattering coefficient bbp. The
average root-mean square difference Δ computed for log-transformed
distributions decreases for $a$ from 0.084 at 412 nm to 0.052 at 490 nm, is
higher for aph(443) (0.149) than for acdm(443) (0.071), and is
approximately 0.165 for bbp at various wavelengths. The SeaWiFS a at
443 and 490 nm, aph at 443 nm and bbp are on average higher than
the MODIS counterparts. Statistics show significant variations in space and
time. There is an overall increasing gradient for Δ associated with
the absorption terms from the open southern and central Adriatic to the
northwest part of the basin, and a reversed gradient for the particulate
backscattering coefficient. For time series analysis, only a(412) and
acdm(443) currently present an unbiased continuity bridging the SeaWiFS
and MODIS periods for the Adriatic Sea. |
