An approach to sea ice classification using dual polarization RADARSAT-2 ScanSAR data is presented in this paper. It based on support vector machine (SVM). In addition backscatter coefficients and gray-level cooccurrence matrix (GLCM) texture features, concentration was introduced as a basis. To better analyze the information of types, we considered two steps that could improve image quality, noise floor stripe reduction incidence angle normalization. Then, effective GLCM characteristics...
Abstract Eutrophication alters the trophic dynamics in lakes and may result biotic homogenization. How nutrient enrichment drives patterns of taxonomic functional (i.e., trait‐based) homogenization macroinvertebrate assemblages at within‐lake (local) among‐lake (regional) scales is, however, not well understood. Taxonomic compositions 41 middle lower reaches Yangtze River Huaihe were analyzed scales. Our results indicated that there was a significant difference among under different status,...
Suffering from speckle noise and complex scattering phenomena, classification results of SAR images are usually noisy shattered, which makes them difficult to use in practical applications. Deep-learning-based semantic segmentation realizes categorization at the same time, thus can obtain smooth fine-grained maps. However, this kind methods require large data sets with pixel-wise categorical annotations, time consuming tedious retrieve. Compared photographs optical remote sensing images,...
The Antarctic ice sheet is an important mass of glacier ice. It particularly sensitive to climate change, and the flow Antarctica's inland glaciers into sea, accelerated by collapsing shelves, threatens global sea level rise. amount snowmelt on surface metric for accurately assessing material loss albedo which affect stability sheet. This study proposes a framework quickly extracting time-series freeze-thaw information at continental scale 40 m resolution taking advantage huge synthetic...
The Yellow River Delta (YRD) wetland is one of the largest and youngest ecosystems in world. It plays an important role regulating climate maintaining ecological balance region. This study analyzes spatiotemporal changes land use, migration, landscape pattern from 2013 to 2022 using Landsat-8 Sentinel-1 data YRD. Then impact human activities are determined by analyzing correlation between socio-economic indicators including nighttime light centroid, total intensity, cultivated area building...
World Heritage sites in general are exposed to the impacts of natural hazards, which threaten their integrity and may compromise value. Floods a severe threat Angkor site. Studies regional floods flood hazard zoning have played an increasingly important role ensuring sustainability This study developed index (FHI) model based on geographic information system (GIS) used synthetic aperture radar (SAR) data extract historical at from 2007 2013. Four indices (flood affected frequency, absolute...
Increased temperature accelerates vital rates, influencing microbial population and wider ecosystem dynamics, for example, the predicted increases in cyanobacterial blooms associated with global warming. However, heterotrophic mixotrophic protists, which are dominant grazers of microalgae, may be more thermally sensitive than autotrophs, thus prey could suppressed as rises. Theoretical meta-analyses have begun to address this issue, but an appropriate framework linking experimental data...
Abstract The direct perturbation of anthropogenic aerosols on Earth’s energy balance [i.e., aerosol radiative forcing (DARF)] remains uncertain in climate models. These uncertainties critically depend optical properties, primarily depth (AOD), single scattering albedo (SSA), and the asymmetry factor g . In this study, we investigate intermodel spread DARF across 14 global models within phase 6 Coupled Model Intercomparison Project (CMIP6), using unified transfer calculation parameter...
How to jointly use spatial and polarimetric information in PolSAR analysis has long been an open question. Benefiting from advanced architectures large visual databases, deep convolutional neural networks or convnets (DCNNs) can generate high-level features achieve state-of-the-art performance image analyses. However, because data are not only multiband but also complex valued, these models cannot be easily borrowed process them. In light of this problem, we develop a new set explore the...
An extreme dust storm hit North China from March 14 to 16, 2021. With the enhanced observations in Beijing, vertical dispersion of long-range transported was investigated perspective atmospheric turbulence. A framework developed by combining two types turbulence intermittency parameter distinguish intermittent or continuous turbulence; thus, evolution and its roles were clearly illustrated on 15, Initially, remained long quiescent period turbulent exchange suppressed significantly, which...
