'''Short description:'''
Products ADG (volume absorption coefficient of radiative flux in sea water due to dissolved organic matter and non algal particles), APH (volume absorption coefficient of radiative flux in sea water due to phytoplankton) and ATOT (volume absorption coefficient of radiative flux in sea water) are described in the PML Inherent Optical Property model (Smyth, T.J., Moore, G.F., Hirata, T. Aiken, J. (2006), a semi-analytic model for the derivation of ocean color inherent optical properties. The RRS product is defined as the spectral ratio of upwelling radiance and downwelling irradiance which can also be expressed as the ratio of normalized water leaving Radiance (nLw) and the extra-terrestrial solar irradiance (F0). The KD490 product identifies the turbidity of the water column, i.e., how visible light in the blue-green region of the spectrum penetrates within the water column. It is directly related to the presence of scattering particles in the water column. Inorganic Suspended Particulate Matter (SPM) is defined as all inorganic matter that stays on a glass fibre filter with an approximate pore size of 0.7 micrometres. Heavy metals and various organic micropollutants adsorb to SPM, the transport of which can affect the ecosystem. High concentrations of SPM cause turbidity which in turn affects the underwater light conditions, thus influencing primary production by phytoplankton and other algae in coastal waters. Products derived from OLCI are Rrs (400, 412, 443, 490, 510, 560, 620, 665, 674, 681, 709) and KD490. From the CCI multiple-sensor product are derived Rrs (410, 443, 490, 510, 560, 665nm), the Inherent Optical Properties, IOPs (ADG, APH, ATOT) and SPM. These products are remapped at nominal 300m (OLCI) and 1 Km spatial resolution using cylindrical equirectangular projection.
'''Description of observation methods/instruments:'''
Ocean colour technique exploits the emerging electromagnetic radiation from the sea surface in different wavelengths. The spectral variability of this signal defines the so called ocean colour which is affected by the presence of phytoplankton. By comparing reflectances at different wavelengths and calibrating the result against in-situ measurements, an estimate of in water absorption parameters can be derived.
