Reference solar irradiance spectra and consequences of their disparities in remote sensing of the ocean colour [PDF]
Annales Geophysicae, 2007 Satellite ocean colour missions require a standard extraterrestrial solar irradiance spectrum in the visible and near-infrared (NIR) for use in the process of radiometric calibration, atmospheric correction and normalization of water-leaving radiances

Blending of ocean colour algorithms applied to the Southern Ocean [PDF]
Remote Sensing Letters, 2010 A method of blending of a specific satellite ocean colour algorithm in the Southern Ocean (SO) with a generic algorithm elsewhere is proposed. The SO is known to have bio-optical properties that require a different bio-optical algorithm for retrieving chlorophyll-a concentration.

Lagrangian and Eulerian time and length scales of mesoscale ocean chlorophyll from Bio-Argo floats and satellites [PDF]
Biogeosciences, 2022 Phytoplankton form the base of marine food webs and play an important role in carbon cycling, making it important to quantify rates of biomass accumulation and loss. As phytoplankton drift with ocean currents, rates should be evaluated in a Lagrangian as

A compilation of global bio-optical in situ data for ocean-colour satellite applications [PDF]
Earth System Science Data, 2016 A compiled set of in situ data is important to evaluate the quality of ocean-colour satellite-data records. Here we describe the data compiled for the validation of the ocean-colour products from the ESA Ocean Colour Climate Change Initiative (OC-CCI ...

Hue-Angle Product for Low to Medium Spatial Resolution Optical Satellite Sensors
Remote Sensing, 2018 In the European Citclops project, with a prime aim of developing new tools to involve citizens in the water quality monitoring of natural waters, colour was identified as a simple property that can be measured via a smartphone app and by dedicated low ...

Superyachts could support satellite ocean colour validation
Frontiers in Remote SensingVisible spectral radiometry of seawater, often referred to as ocean colour, from space, provides a synoptic view of surface phytoplankton, and other optically-active constituents, at high temporal resolution, that is unsurpassed by any other technology ...
