On the Adequacy of Representing Water Reflectance by Semi-Analytical Models in Ocean Color Remote Sensing

open access: yesRemote Sensing, 2019
Deterministic or statistical inversion schemes to retrieve ocean color from space often use a simplified water reflectance model that may introduce unrealistic constraints on the solution, a disadvantage compared with standard, two-step algorithms that ...

Radiation Sensitivity Analysis of Ocean Wake Information Detection System Based on Visible Light Remote Sensing

open access: yes, 2022
Various ships and submerged moving objects in the ocean are key targets of numerous remote sensors. Wake has developed into one of the key detection targets of ocean visible light remote sensing as the visible trail information left by moving objects on ...

Global patterns of treeline predictability and the gap between the forest and the treeline

open access: yesEcography, EarlyView.
The alpine treeline is the highest elevation at which trees can grow, which is assumed to be controlled by temperature and globally predictable. However, many upper forest limits (UFLs) do not reach this elevation, due natural factors and human disturbance.

Neural Network Reflectance Prediction Model for Both Open Ocean and Coastal Waters

open access: yesRemote Sensing, 2020
Remote sensing of global ocean color is a valuable tool for understanding the ecology and biogeochemistry of the worlds oceans, and provides critical input to our knowledge of the global carbon cycle and the impacts of climate change.

Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

open access: yesInternational Journal of Climatology, EarlyView.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

Estimation of Chlorophyll-a in Northern Coastal Bay of Bengal Using Landsat-8 OLI and Sentinel-2 MSI Sensors

open access: yesFrontiers in Marine Science, 2019
Chlorophyll-a can be used as a proxy for phytoplankton and thus is an essential water quality parameter. The presence of phytoplankton in the ocean causes selective absorption of light by chlorophyll-a pigment resulting in change of the ocean color that ...

A New Hydroclimatic Signature: Negative NAO Dominance Under Weak La Niña Conditions During the 2025–2026 Northwest Africa Floods

open access: yesInternational Journal of Climatology, EarlyView.
Conceptual hydroclimatic pathway linking the concurrent negative North Atlantic Oscillation (NAO) phase and weak La Niña conditions to extreme February rainfall and flash flooding in Northwest Africa. ABSTRACT The winter of 2025–2026 in Morocco exhibited a rapid hydroclimatic transition from prolonged drought to widespread flooding, representing an ...

Improving Daily Rainfall Downscaling Over Taiwan's Complex Terrain With Surface‐Wind‐Informed Deep Learning Model

open access: yesInternational Journal of Climatology, EarlyView.
An encoder–decoder architecture (EDA) dynamically downscales coarse‐resolution climate fields (0.25°) to high‐resolution outputs (0.05°) over Taiwan, improving the representation of fine‐scale spatial variability and localized extremes by incorporating both rainfall and surface winds to maintain physical consistency.

Study of Marine Ecosystems and Biogeochemistry Now and in the Future: Examples of the Unique Contributions from Space [PDF]

open access: yesOceanography, 2010
Ocean color remote sensing has profoundly influenced how oceanographers think about marine ecosystems and their variability in space and time. Satellite ocean color radiometry (OCR) provides a unique perspective for studying the processes regulating ...
