Sentinel 3 OLCI Document Library
This is a Product Notice for the public release of Sentinel-3 Ocean and Land Colour Instrument (OLCI) Level-1B products at Non Time Critical (NTC) timeliness. The status and limitations also apply to the OLCI Level 1B products at Near Real Time (NRT) timeliness.
The Notice describes the OLCI current processing baseline, product and quality limitations, and product availability status.
This document is intended to provide the description of the Sentinel-3 products that will be generated within the Sentinel-3 Payload Data Ground Segment by the Sentinel-3 Instrument Processing Facilities (IPFs).
In the frame of pre-launch and commissioning activities for Sentinel-3's OLCI-A instrument, Spectral Response Functions (SRF) based on on-ground and inflight characterisation measurements were derived. They are described in this technical note.
This Technical Note is aimed at describing the Sentinel-3 Optical Test Data Sets (TDS) provided to the user community and the limitations of the TDS'. No detail on the tools used for the generation of the TDS will be provided, but only a high level description.
The Sentinel-3 Mission Guide provides a high-level description of the mission objectives, satellite description and ground segment. It also covers an introduction to heritage missions, thematic areas and services, orbit characteristics and coverage, instrument payloads and data products.
This document aims to identify and specify the common definitions, structures and conventions of the Sentinel-3 products from Level 0 up to Level 2.
This Technical Note provides the File Naming Convention adopted by the Sentinel-3 PDGS for the following data classes:
The purpose of this document is to define the product structure and the content of each file generated and delivered by the POD Service Centre and the Sentinel-3 NRT POD Instrument Processing Facility (IPF) across its interfaces to the Sentinels (1, 2 and 3) Payload Data Ground Segments (PDGSs).
This document aims to identify and specify the format of Sentinel-3 OLCI products from Level 1 up to Level 2, browse products included.
NB: The product specifications reflect the current operation processor implementation - IPF V05 - they still could be updated before launch or during the commissioning phase.
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 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.
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.
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.
