With the growing demand for global water environment monitoring, satellite laser altimeters (SLA) have considerable advantages underwater measurements. However, changes in suspended solids, turbidity, and other optical properties of affect propagation SLA pulses water. This can accuracy reliability study analyzed impact quality Oahu Island region Hawaii on un-derwater measurements based ICESat-2, MODIS, Landsat-8, situ data. Underwater photons were obtained from ICESat-2 ATL03 data through an Adaptive Elevation Difference Threshold, combined with to calculate potential altimetry deviation. Using inverted Landsat-8 as a reference, MODIS kd490 was implemented random forest regression. The quantified by combining bias that matched footprint. There is positive correlation between photon permeability. more turbid quality, smaller proportion penetrate surface. maximum measurement deviation caused multiple scattering body could reach meter level. Future bathymetry corrections need consider scattering. findings are importance environmental protection, resource management, policy formulation, processing.

Owing to rapid urbanization, the Beijing–Tianjin–Hebei region in China faces considerable urban heat island (UHI) effects, which can be mitigated by blue-green space construction. In this study, we used multi-source remote sensing products and InVEST model’s cooling module analyze spatiotemporal changes effects from 1990 2020. The wavelet coherence theory was explore these changes, as well environmental factors that affect cooling. key findings indicate effect is closely related similar trends significant temporal differences indices were observed central areas, fringe, city center. addition, climatic such temperature precipitation substantially influenced cooling, with an average of 0.88. Seasonal variations notable, exhibiting best across all time–frequency scales (averaging 0.55). highlight critical role spaces for mitigating UHI provides scientific insights planning management.

In recent decades, the Loess Plateau has undergone rapid urbanization alongside extensive afforestation efforts aimed at controlling soil erosion. These large-scale land use changes have inevitably affected region’s hydrological cycle. Despite these changes, impact on groundwater not been thoroughly investigated. This study aims to examine spatial and temporal evolution of storage (GWS) in from 2003 2022, identify driving factors behind evaluate sustainability levels through Reliability–Resilience–Vulnerability framework. GWS were estimated using GRACE gravity satellite data Global Land Assimilation Dataset (GLDAS). Our also analyzed drivers by integrating change data, ERA5-Land reanalysis various statistical data. findings indicate a decline rate −6.9 ± 3.84 mm/yr. Seasonal variations show that is relatively higher spring autumn, but lower summer winter. The eastern part particular experiencing 150% overall regional average. Groundwater currently critically unsustainable level, with conditions west being more favorable compared central regions. Climate such as precipitation, evaporation, runoff did significant correlation changes. Increases forest areas water consumption together explained 95.8% GWS, area growth dominant factor. Human activities are identified main cause decline. study’s improve our understanding dynamics offer scientific basis for formulating resource management ecological restoration policies region.

The widely distributed surface water bodies (e.g., lakes and reservoirs) are important components of resources on Earth, their spatial–temporal dynamics can pose significant effects regional resources. Previous studies generally attributed variability in terrestrial storage (TWS) to groundwater dynamics, hardly considering changes, making the influence changing TWS unclear. Here, by taking Hulun Lake as an example, which occupies 94.0 % total areas target basin, we quantitatively revealed impacts changes lake volume TWS. Using cloud computing-based body monitoring altimetry satellite-based level measurements, found continuous shrinkage (25 km2/yr) before 2012 while rapid expansion after that. By coupling with levels, annual volumes were estimated. We showed that also significantly declined (−0.52 km3/yr) 2012, then rapidly restored (0.65 due increasing recharge from rivers. rate was higher than (0.15 km3/yr), indicating great contribution increases gains. Our study highlights considerable it is essential consider when attributing drivers regions experiencing dramatic changes. method proposed applicable evaluating other similar around world.
