Abstract The maximum annual freeze depth (MFD) is a primary indicator of the thermal state frozen ground, affecting ecosystems, hydrological processes, vegetation growth, infrastructure, and human activities in cold regions. It thus important to quantify past, present, future spatial temporal variability MFD at hemispheric scale. We develop data‐driven simulation method within machine learning framework, integrating observations from meteorological stations several environmental predictors,...
Particle matter (PM) emitted from coal combustion can cause great harm to human health and the environment. The existence of hazardous trace element arsenic (As) in PM intensifies its toxicity. In this work, four particle sizes fly ash (PM<1, PM1–2.5, PM2.5–10, PM>10) before electrostatic precipitator (ESP) a 600 MW coal-fired power plant were sampled by Dekati low pressure impactor (DLPI). sample, bottom ash, ESP (ESP ash) collected simultaneously. Concentrations total valent As (As3+ As5+)...
Abstract. The accurate and rapid extraction of glacier boundaries plays an important role in the study inventory, change movement. With successive launches high-resolution remote-sensing satellites increasing abundance available data, great opportunities challenges now exist. In this study, we improved DeepLab V3+ as Attention designed a complete solution based on network to automatically extract outlines from Gaofen-6 panchromatic multispectral (PMS) images with spatial resolution 2 m....
Premature stress of cement concrete pavements is the coupled action construction technique, structural material and environmental action. It quite difficult to accurately get actual distribution merely based on theoretical or simulation analysis. Therefore, in-situ health monitoring particularly significant obtain strain information for assessment performance pavements. To contribute this topic, different kinds FBG sensors have been specially designed measure temperature, pressure...
Abstract Seasonally frozen ground (SFG) in the Northern Hemisphere (NH) plays a significant role earth system via changes freeze‐thaw cycle. Previous studies primarily focus on permafrost; however, SFG response to climate change hemispheric scale is uncertain due lack of observations. We rectify this with newly assembled comprehensive database 1,220 stations daily To quantify spatiotemporal characteristics change, we calculate eight variables these observations: first date soil freeze (FFD),...
Reconstructing Holocene vegetation history and human impact on is critical for understanding past interactions between humans nature. This study concentrates the lower West River area in Southern China, offering high-resolution reconstructions of changes over last 9000 years. Our findings reveal that during Climatic Optimum (9–5 ka BP), was predominantly covered by dense evergreen broad-leaved forests. Around 5.1 BP, emergence marsh forests, as evidenced abundant pollen Glyptostrobus situ...
Abstract Active volcanoes in East Asia pose potential threats to the surrounding areas. The eruptive history of many Japanese are well understood, but their dispersal pathways often based on visible tephra. Additionally, other important region still require a deeper understanding potential. Here, we explore Holocene cryptotephra record preserved marine core 13PT‐P4 southwestern Sea, order better reconstruct past events and dispersal. Six widespread tephra layers identified correlated source...
Relative pollen productivity (RPP) is a key parameter for quantitative reconstruction of past vegetation cover. However, RPP estimates are rarely obtained in the subtropical and tropical regions. In this study, extended R-value (ERV) model was used to estimate major plant taxa evergreen broadleaved mixed forests middle China based on soil samples data from 23 sites. The best result with combinations ERV sub-model 3 Prentice’s or 1/d distance-weighting method. relevant source area (RSAP)...
Carbon fiber-reinforced polymer (CFRP) components were extensively used and current studies mainly refer to CFRP laminates. The dynamic performance of the complicated antenna beams is yet be explored. Therefore, a sensor layout based on fiber Bragg gratings (FBGs) in series was designed measure response beam, various vibration tests (sweep frequency test, simulated long-life shock functional constant test) conducted. time domain analysis FBG sensing signals performed check assess health...
