This Product Notice addresses both Sentinel-3A and -3B Ocean and Land Colour Imager (OLCI-A and OLCI-B) Level-1B processing baselines deployed on 30/07/2019. It is applicable to Near Real Time (NRT) and Non-Time Critical (NTC) timeliness.
This is a Product Notice for the public release of Sentinel-3 Ocean and Land Colour Instrument (OLCI) Level-2 products at Near Real Time (NRT) and Non Time Critical (NTC) timeliness.
The Notice describes the OLCI current processing baseline, product and quality limitations, and product availability status.
The confidence check ATBD defines the OLCI classification flags and details of example quality flags that will provide the end users with confidence in the OLCI products.
This ATBD describes the impact of the relevant absorption features due to atmospheric gases within the spectral domain of OLCI. Procedures will be discussed to correct the influence of atmospheric gas absorption for those OLCI channels, which are significantly affected.
The aim of the classification is to distinguish water and land i.e. it will be designed to separate pixels into the water and land chains as there is currently no OLCI atmospheric processing chain.
This ATBD describes the algorithm for the determination of inherent optical properties (IOPs) and the concentration of water constituents in case 2 waters from water leaving radiance reflectance spectra to be used for the Ocean and Land Colour Imager (OLCI) of the Earth Observation Mission Sentinel-3 of the European Space Agency (ESA).
This ATBD describes the retrieval of water vapour from OLCI measurements above land, ocean and clouds.
The purpose of this algorithm is to determine the correction for NIR reflectance needed for the full atmosphere correction model - applied to visible wavelengths.
The purpose of this document is to lay out algorithms for the sea water transparency products.
The purpose of this document is to lay out algorithms for the OLCI ocean colour products in Case 1 waters.
The purpose of this document is to lay out the OLCI atmospheric correction algorithm above Case 1 waters.
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 called the OLCI Terrestrial Chlorophyll Index (OTCI) is a unique chlorophyll index for OLCI data. This document identifies the source of input data; outlines the physical principles and mathematical background; justifies this algorithm and then explores its limitations and assumptions.
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 for the carbon-cycle modellers to convert the measured chlorophyll concentration into an estimate of ocean productivity, and hence of carbon sequestration.
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 wavelength.
It describes an algorithm that (a) properly accounts for the instrument spectral characterisation to convert TOA radiances into TOA reflectances and (b) provides a first order correction of the TOA reflectance for the wavelength variation, accounting for the surface underneath.
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 pollution (maximum Operating Zenith Angle, OZA, of 55°).
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 Colour Imager (OLCI) on Sentinel 3. The procedure is an alternative method to the standard atmospheric correction procedure for OLCI. Its main purpose is to improve the atmospheric correction over turbid and highly absorbing case 2 water and for areas of an image which are contaminated by sun glint. However, it can be applied also to case 1 water.
