Consistent nutrient mapping from Sentinel-2 and Sentinel-3 in nearshore waters: A case study in Xiamen Bay

Ecological Informatics
High-resolution monitoring of nutrient concentrations is essential for assessing water quality in coastal and bay regions. This study proposes a two-step framework to map dissolved inorganic nitrogen (DIN) and phosphorus (DIP) concentrations at high ...

Global Sensitivity Analysis of the SCOPE Model in Sentinel-3 Bands: Thermal Domain Focus

Remote Sensing, 2019
Sentinel-3 satellite has provided simultaneous observations in the optical (visible, near infrared (NIR), shortwave infrared (SWIR)) and thermal infrared (TIR) domains since 2016, with a revisit time of 1−2 days.

Diverse Seasonal Patterns of Precipitation and Terrestrial Water Storage Over the Indochina Peninsula: Roles of Monsoons, ENSO, and Topography

Hydrological Processes, Volume 40, Issue 4, April 2026.
Warm ENSO phase events weaken Asian monsoons, reducing precipitation and TWS in northern and southern ICP, while central ICP's bowl‐shaped topography increases TWS. Seasonally, the Indian Monsoon brings abundant rainfall during May–September, which lags into TWS by 2 months.

Assimilation of solar‐induced fluorescence satellite observations in the European Centre for Medium‐Range Weather Forecasts integrated forecast system

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.
This work demonstrates the potential of the assimilation of satellite solar‐induced fluorescence (SIF) retrievals at eight‐day and 0.1° resolutions in the integrated forecast system (IFS), developed at the European Centre for Medium‐Range Weather Forecasts (ECMWF), at global scale, to provide a more realistic representation of the vegetation temporal ...

Statewide Intensification of Harmful Algal Blooms Across California Lakes and Reservoirs

GeoHealth, Volume 10, Issue 4, April 2026.
Abstract Monitoring cyanobacteria is crucial for assessing water quality, safeguarding public health, and understanding ecosystem dynamics impacted by harmful algal blooms. This study explores the potential of satellite remote sensing (SRS) to assess risks of cyanotoxin exposure in California's recreational waters from 2002 to 2011 and 2016 to 2023 ...

A Phenoregion Approach to Understanding Chlorophyll‐a Seasonal Cycles and Interannual Variability in the South‐West Indian Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The South‐West Indian Ocean (SWIO) displays marked spatial variations in physical forcings, driving in turn distinct seasonal biogeochemical regimes. Mesoscale eddies in the Mozambique Channel drive large‐scale redistribution of nutrients and plankton, while eastern Madagascar waters are highly oligotrophic.

Empirical model for chlorophyll-a determination in inland waters from the forthcoming Sentinel-2 and 3. Validation from HICO images

Revista de Teledetección, 2014
Chlorophyll-a concentration is one of the main indicators of inland waters quality. Using CHRIS/PROBA images and in situ data obtained in four lakes in Colombia and Spain, we obtained empirical models for the estimation of chlorophyll-a concentration ...
