Entering the Era of Directly Supporting Society With Observation‐Based Ocean Acidification Data

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Ocean acidification is a growing concern for many nations around the world. However, our capacity to monitor changes in carbonate chemistry with sufficient spatial and temporal resolution, has until now, been limited, which has impeded effective action and decision‐making at international, national, and regional levels.

A Sensitivity Analysis of Flick‐AccuRT, a Coupled Ocean‐Atmosphere Radiative Transfer Model and Input Module

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Radiative transfer (RT) models typically solve the radiative transfer equation separately in either the atmosphere or the ocean, limiting accuracy across the atmosphere‐ocean interface. Here, we employ a coupled scalar discrete ordinate RT model to examine methods for the input of measured inherent optical properties (IOPs) of oceanic ...

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 ...

Comparison of iCOR and Rayleigh atmospheric correction methods on Sentinel-3 OLCI images for a shallow eutrophic reservoir

PeerJ, 2022
Remote sensing of inland waters is challenging, but also important, due to the need to monitor the ever-increasing harmful algal blooms (HABs), which have serious effects on water quality. The Ocean and Land Color Instrument (OLCI) of the Sentinel-3 satellites program is capable of providing images for the monitoring of such waters.

A Validation of OLCI Sentinel-3 Water Products in the Baltic Sea and an Evaluation of the Effect of System Vicarious Calibration (SVC) on the Level-2 Water Products

Remote Sensing
The monitoring of coastal waters using satellite data, from sensors such as Sentinel-3 OLCI, has become a vital tool in the management of these water environments, especially when it comes to improving our understanding of the effects of climate change ...

High‐ and Low‐Concentration Spiral Chlorophyll Bands Excited by Vortex Rossby Waves

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract High‐concentration spiral chlorophyll bands (HSCBs) embedded in oceanic mesoscale eddies have recently been observed worldwide. They are considered to be the footprints of vortex Rossby waves (VRWs). Based on satellite observations and drifter data, we identified additional low‐concentration spiral chlorophyll bands (LSCBs).

The Use of Sentinel-3/OLCI for Monitoring the Water Quality and Optical Water Types in the Largest Portuguese Reservoir

Remote Sensing, 2022
The Alqueva reservoir is essential for water supply in the Alentejo region (south of Portugal). Satellite data are essential to overcome the temporal and spatial limitations of in situ measurements, ensuring continuous and global water quality monitoring. Data between 2017 and 2020, obtained from OLCI (Ocean and Land Color Instrument) aboard Sentinel-3,

Monitoring phycocyanin concentrations in high-latitude inland lakes using Sentinel-3 OLCI data: The case of Lake Hulun, China

Ecological Indicators, 2023
With the intensification of global warming, eutrophication in lakes at high latitudes of China has become increasingly severe, with the harm of blue-green algae blooms also on the rise.
