Assessment of Atmospheric Correction Algorithms for Sentinel-3 OLCI in the Amazon River Continuum

Remote Sensing
Water colour remote sensing is a valuable tool for assessing bio-optical and biogeochemical parameters across the vast extent of the Amazon River Continuum (ARC). However, accurate retrieval depends on selecting the best atmospheric correction (AC). Four AC processors (Acolite, Polymer, C2RCC, OC-SMART) were evaluated against in situ remote sensing ...

A new benchmark for spatiotemporal fusion of Sentinel-2 and Sentinel-3 OLCI images

Earth Science Informatics
Abstract In Earth Observation, the use of multiple sensors has gained considerable attention as a tool to overcome the limitations inherent in individual data. Despite this, the operational lifespans of sensors are finite, creating an ongoing need to explore and integrate new sensors to sustain critical Earth Observation capabilities across ...
