While satellite remote sensing has emerged as a powerful tool for large-scale water quality monitoring across diverse aquatic ecosystems, a systematic analysis of water optical properties in rivers remains limited, restricting its use in supporting Sustainable Development Goal (SDG) monitoring. This study presents the first comprehensive analysis of water transparency (Secchi disk depth, Z<sub>SD</sub>) and color (Forel-Ule Index) in the five large rivers (Yangtze, Danube, Mississippi, Nile, and Amazon) using Sentinel-2 MSI data (2019–2021). Results reveal significant spatial-seasonal variations: Danube had the highest transparency (Z<sub>SD</sub>) and bluest color (FUI), followed by Nile, Yangtze, Mississippi, and Amazon. These differences were primarily driven by basin-specific soil erodibility and precipitation. Spatially, the Yangtze, Mississippi, and Amazon exhibited decreasing Z<sub>SD</sub> and increasing FUI from their upper to lower reaches, contrasting with different trends in Danube and Nile, highlighting the influence of large dams. Seasonally, two different patterns were observed in the five rivers, underscoring the hydrological influences on water optical properties. Furthermore, as two key optical water quality parameters, Z<sub>SD</sub> and FUI were analyzed for their complementary roles in characterizing river turbidity across varying water conditions. By quantifying spatiotemporal patterns, this study establishes a global baseline for river optical properties and supports SDG 6.3.2 monitoring.

By treating voids as the 3D regions between the digital elevation model (DEM) or digital surface model (DSM) where no returns are detected, our method bypasses canopy-centric metrics and simplified radiative assumptions, yielding a scalable, assumption-light representation of forest architecture. Across sites, void configurations reflect underlying stand architecture. Forests with high structural heterogeneity—multi-layered canopies and irregular stem distributions—exhibit diffuse, vertically extensive voids. In contrast, structurally uniform stands contain more confined voids, largely restricted to lower strata because of diminished understory development. These patterns demonstrate that forest voids integrate overstory and understory attributes, providing a structural lens on spatial openness under diverse conditions. Although challenges in scalability and independent validation remain, extending this framework to multi-platform LiDAR will enable broader applications in biodiversity monitoring, habitat suitability, and climate-adaptation research.

HY-1E, the new-generation ocean color satellite following HY-1D, offers improved spatial resolution, an expanded spectral range, and a reduced revisit time. These improvements are expected to advance remote sensing applications in SDB. Prior to its operational application, a systematic assessment of HY-1E’s bathymetric retrieval capability is essential. In this study, we evaluate the performance of HY-1E imagery for SDB using an ICESat-2-assisted approach across multiple study areas, acquisition times, and image types.

Despite being located within a similar latitudinal band, the two regions exhibited contrasting cloud regimes due to variations in meteorological conditions, boundary-layer structure, and convective forcing. Satellite observation analyses showed that vertical development of clouds was generally deeper and more vertically continuous over Oklahoma, while clouds over Korea were typically shallower and more seasonally variable, especially confined to lower altitudes during winter. The analysis of radiative heating indicates that relatively stronger shortwave heating and longwave cooling frequently occur in the upper troposphere over Oklahoma, consistent with deep convective systems. In contrast, Korea exhibited heating rates that were dominant below the mid troposphere, associated with relatively weak vertical development of clouds. Thermodynamic analysis using equivalent potential temperature and relative humidity profiles showed that the atmospheric conditions over Korea were relatively more stable and humid, and exhibited greater seasonal variability compared to those over Oklahoma. Our findings showed that cloud radiative characteristics between Oklahoma and Korea regions were notably different based on long-term satellite observations.
