| Validation of the “geophysical products” derived from observations of satellite ocean colour sensors requires the collection of the same parameters from in situ instrumentation. In particular, the irradiance reflectance or the remote sensing reflectance have to be determined from field measurements of radiometric quantities such as the upward and downward plane irradiances at various depths in the water column. This task has been performed in the frame of the BOUée pour l’acquiSition d’une Série à Long termE (BOUSSOLE) project by using a commercial radiometer system specifically designed for that purpose. This system is built by the Satlantic company (Halifax, Nova Scotia, Canada). It is composed on an in-water profiling radiometer called the “SeaWiFS... |

| The validation of the “geophysical products” derived from observations of the satellite ocean colour sensors requires the collection of the same parameters from in situ instrumentation. In this report, we focus on the validation of the water-leaving reflectance, and we examine a protocol issue, which is linked to the different ways of deriving at sea a water-leaving reflectance value that is suitable for the validation of this product as it is derived in particular from the MERIS ocean colour sensor observations (see at http://www.envisat/esa.int). The two techniques that we have tested use two very different instrument types. The first one measures the upwelling irradiance in the water column in a free-fall profiling mode, using a multi-channel... |
