Sentinel-3 Synergy Level-2 and Level-3 ATBD
This document describes the algorithms for synergistic processing of data from SLSTR and OLCI to (i) retrieve aerosol optical properties and surface reflectance for cloud-free atmospheres over land ...
Sentinel-3 OLCI Rayleigh Correction over Land ATBD
The Bottom of Rayleigh Reflectance (BRR) is a level 2 product over land that can be used in pixel classification. The Rayleigh correction formulation, defined for MERIS, remains pertinent for OCL ...
Sentinel-3 OLCI FAPAR ATBD
This Algorithm Theoretical Basis Document (ATBD) describes the Joint Research Centre (JRC)- procedure used to retrieve information of absorbed photosynthetical radiation by the vegetated terrestr ...
Sentinel-3 OLCI Bright Waters Atmospheric Correction ATBD
The purpose of this algorithm is to determine the correction for NIR reflectance needed for the full atmosphere correction model - applied to visible wavelengths.
Sentinel-3 SLSTR Land Surface Temperature ATBD
This document presents the Algorithm Theoretical Basis Document (ATBD) for the retrieval of Land Surface Temperature (LST) from thermal radiances measured by the Sea and Land Surface Temperature Ra ...
Sentinel-3 SLSTR - Active Fire: Fire Detection and Fire Radiative Power ATBD
This document describes the theory for the prototype multi-channel active fire detection and fire characterisation algorithm for use with data from the SLSTR sensor onboard the ESA Sentinel-3 satel ...
Sentinel-3 SLSTR Sea Surface Temperature ATBD
This document describes the physical and statistical basis for estimation of Sea Surface Temperature (SST) and associated errors in SST, for products of the SLSTR instrument.
Sentinel-3 OLCI Transparency Products ATBD

Sentinel-3 OLCI Terrestrial Chlorophyll Index ATBD
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 ...
Sentinel-3 OLCI Photosynthetically Active Radiation ATBD
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 ...
