| Zusammenfassung |
| This paper presents the Mediterranean Ocean Colour Observing System in the
framework of the growing demand of near real-time data emerging within the
operational oceanography international context. The main issues related to
the satellite operational oceanography are tied to the following: (1) the near real-time
ability to track data flow uncertainty sources; (2) in case of failure, to
provide backup solutions to end-users; and (3) to scientifically assess the
product quality. We describe the major scientific and technological steps
made to develop, maintain and improve the operational system and its
products. A method for assessing the near real-time product quality is
developed and its limitation discussed. Main results are concerned with the
degradation, starting from mid-2010, of the MODIS Aqua channel at 443 nm
with its successive recovery thanks to the new calibration scheme implemented
in the recently released SeaDAS version 6.4. The product validation analysis
highlights that SeaWiFS chlorophyll product over the Mediterranean Sea is
the best performing in comparison with those of MODIS and MERIS. Despite
their general good agreement with in situ observations, MODIS- and
MERIS-derived chlorophyll present a slight and systematic underestimation of
the in situ counter part. The most relevant implications induced by these
results are discussed from an operational point of view. |
