Identificação de áreas úmidas na região costeira leste do Estado do Rio de Janeiro a partir do Índice de Água por Diferença Normalizada Modificado (MNDWI)

, 2023
As Áreas Úmidas (AUs) brasileiras, apesar de prestarem inúmeros serviços ambientais, sofrem de crescente descaracterização, principalmente, em regiões densamente povoadas, por não haver reconhecimento de tais funções. Nos municípios costeiros do estado

Divergent Blue Carbon Trajectories in the Yellow River Delta Post‐1976 Diversion: Hydrological Stability and Human Disturbance Contrasts Revealed by Multi‐Source Remote Sensing (1984–2023)

Land Degradation &Development, Volume 37, Issue 15, Page 11417-11437, September 2026.
ABSTRACT Coastal wetlands are critical blue carbon sinks, yet their spatiotemporal dynamics under environmental change remain insufficiently quantified. Taking the Yellow River Delta (YRD) as a natural laboratory, this study synthesizes multi‐source remote sensing data, including optical and radar imagery spanning from 1984 to 2023, to explore the ...

Assessing SWOT's Measurement Capabilities in the Complex Paraná River

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Estimating water surface elevation (WSE) is crucial for understanding hydrological processes; however, many rivers remain insufficiently monitored due to the limitations of in situ gauge networks. The Surface Water and Ocean Topography (SWOT) mission, equipped with Synthetic Aperture Radar technology, enables global monitoring of WSE with high

Dragonfly functional connectivity responses are dynamic relative to drought

Insect Conservation and Diversity, Volume 19, Issue 5, Page 1156-1169, September 2026.
During drought, dragonfly species richness decreases. Yet, dragonfly assemblages show a higher propensity for dispersal during drought. Dispersal pathways vary among the wet and dry periods, and relative to temporal changes in the landscape. While some dragonfly species can traverse plantation compartments, conservation corridors facilitate functional ...

The Application of Modified Normalized Difference Water Index (MNDWI) by Leaf Area Index in the Retrieval of Regional Drought Monitoring [PDF]

, 2015
The vegetation coverage is one of the important factors that restrict the accuracy of remote sensing retrieval of soil moisture. In order to effectively improve the accuracy of the remote sensing retrieval of soil moisture and to reduce the impact of ...

Seasonal Variations of the Relationship between Spectral Indexes and Land Surface Temperature Based on Local Climate Zones: A Study in Three Yangtze River Megacities

Remote Sensing, 2023
Urban heat islands are representative problems in urban environments. The impact of spectral indexes on land-surface temperature (LST) under different urban forms, climates, and functions is not fully understood.

Floods From Space: How Remote Sensing, AI, and Cloud Platforms Are Reshaping Disaster Risk Reduction

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Flooding remains one of the most damaging climate‐related hazards globally, yet flood remote sensing has historically developed largely along sensor‐specific pathways. This review addresses the need for a systematic and decision‐oriented synthesis of how space‐borne remote sensing has evolved toward integrated flood monitoring and disaster ...
