Validation of ocean colour sensors onboard ESA satellites
Radiometric measurements (surface irradiance Es(λ), a subsurface radiance sensor Lu(λ) and four subsurface irradiance sensors Ed(z) attached at nominal depths (z) of 2, 4, 8, and 16 m the radiometer used for these measurements was a tethered attenuation coefficient chain sensor (TACCS) manufactured by Satlantic Inc.)
Atmospheric measurements (aerossol optical tickness, atmospheric pressure, water vapor measure with a Microtops II® Sunphotometer)
