<abstract>
<p>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 &lt;i&gt;a&lt;/i&gt;, phytoplankton
absorption &lt;i&gt;a&lt;/i&gt;&lt;sub&gt;ph&lt;/sub&gt;, absorption associated with colored detrital material
(CDM) &lt;i&gt;a&lt;/i&gt;&lt;sub&gt;cdm&lt;/sub&gt;, and particle backscattering coefficient &lt;i&gt;b&lt;/i&gt;&lt;sub&gt;bp&lt;/sub&gt;. 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 &lt;i&gt;a&lt;/i&gt;&lt;sub&gt;ph&lt;/sub&gt;(443) (0.149) than for &lt;i&gt;a&lt;/i&gt;&lt;sub&gt;cdm&lt;/sub&gt;(443) (0.071), and is
approximately 0.165 for &lt;i&gt;b&lt;/i&gt;&lt;sub&gt;bp&lt;/sub&gt; at various wavelengths. The SeaWiFS &lt;i&gt;a&lt;/i&gt; at
443 and 490 nm, &lt;i&gt;a&lt;/i&gt;&lt;sub&gt;ph&lt;/sub&gt; at 443 nm and &lt;i&gt;b&lt;/i&gt;&lt;sub&gt;bp&lt;/sub&gt; 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 &lt;i&gt;a&lt;/i&gt;(412) and
&lt;i&gt;a&lt;/i&gt;&lt;sub&gt;cdm&lt;/sub&gt;(443) currently present an unbiased continuity bridging the SeaWiFS
and MODIS periods for the Adriatic Sea.</p>
