Advances in Marine Optics Technology: JRC Hyperspectral Free-fall Profiler
The Copernicus Sentinel-3 missions, which include the operational Sentinel-3A and -3B, as well as the upcoming Sentinel-3C and -3D, present an unparalleled opportunity for long-term Ocean Colour (OC) monitoring that supports global environmental and climate research, as well as the development, implementation and monitoring of EU legislations. OC missions delivering fit-for-purpose data require comprehensive calibration and validation activities ensuring the indirect calibration of space-based sensors and the validation of derived data products. These activities heavily rely on accurate in situ reference measurements, which in turn depend on advanced measurement techniques and cutting-edge instrumentation.
Since the initiation of operational OC missions in 1997, the Joint Research Centre (JRC) has played a pivotal role in sustaining the necessary calibration and validation activities, developing specialized expertise and establishing dedicated measurement programs and infrastructure, which are now assisting current Copernicus OC missions.
The provision of state-of-the-art reference in situ data, critical for delivering quality-assured satellite-derived marine data products, relies on technological developments. With the aim of transferring JRC know-how to the wider user community, this Technical Report details recent technological advancements made at the JRC Marine Optical Laboratory (MarLab) for realizing a hyperspectral free-fall profiler to support the validation of satellite-based OC products.
