The purpose of this document is to lay out algorithms for the sea water transparency products.

This Algorithmic Theoretical Basis Document (ATBD) describes the algorithm used to estimate chlorophyll content over land from Level-1 OLCI products from the Sentinel-3 mission. The algorithm calle ...

Photosynthetically Active Radiation (PAR) reaching the ocean surface is defined as the quantum energy flux from the Sun in the spectral range 400-700 nm; units are Einstein/m2/day. PAR is essential ...

The purpose of this ATBD is to define the approach to white cap correction that could be applied to OLCI.

This document aims at providing a comprehensive description of the OLCI instrument's spectral characteristics and their potential impact on algorithms likely to expect data acquired at a constant w ...

This ATBD discusses the potential approaches to correct sun glint for OLCI. The amount of sun glint will be reduced as compared to MERIS; the field-of-view (FOV) is tilted to reduce the sun-glint p ...

This ATBD describes a procedure to derive the bi-directional water leaving radiance reflectances (RL_w) from top of atmosphere (TOA) radiance reflectance spectra RL_toa (L1b data) of the Ocean Land ...
