A new 11 year (2004–2014) monthly 1° gridded Argo temperature and salinity data set with 49 vertical levels from the surface to 1950 m depth (named BOA-Argo) is generated for use in ocean research modeling studies. The produced based on refined Barnes successive corrections by adopting flexible response functions a series of error analyses minimize errors induced nonuniform spatial distribution observations. These allow BOA-Argo capture greater portion mesoscale large-scale signals while...
The quantification of the extent and dynamics land-use changes is a key metric employed to assess progress toward several Sustainable Development Goals (SDGs) that form part United Nations 2030 Agenda. In terms anthropogenic factors threatening conservation heritage properties, such aids in assessment achievements sustainability solving problem insufficient data availability. Therefore, this study, 589 cultural World Heritage List (WHL) properties from 115 countries were analyzed,...
Affected by natural and human-induced factors, cultural heritage sites their surroundings face threats of structural instability land displacement. Accurate rapid identification the key areas facing existing or potential deformation risks is essential for conservation sustainability sites, particularly huge archaeological regions. In recent years, successful application differential radar interferometry techniques measurement millimeter-level terrain motions has demonstrated monitoring...
Cultural heritage sites are rare and irreplaceable wealth of human civilization. The majority them becoming unstable due to a combination natural disturbances. High-precision, efficient deformation monitoring facilitates the early recognition potential risks enables preventive diagnosis sites. In this study, an advanced Multi-Temporal Interferometric Synthetic Aperture Radar (MTInSAR) approach was developed by jointly analyzing Persistent Scatterers (PSs) Distributed (DSs) using...
The Qinghai-Tibet Plateau (QTP) is an area sensitive to global climate change, and land use/land cover change (LUCC) plays a vital role in regulating system at different temporal spatial scales. In this study, we analyzed the trend of precipitation characteristics LUCC on QTP. Meanwhile, also used normalized difference vegetation index (NDVI) as indicator discuss relationship between precipitation. results show following: (1) Annual showed fluctuant upward rate 11.5 mm/decade from 1967 2016;...
In this paper, an essential modulation transfer function (MTF) on synthetic aperture radar (SAR), denoted as tilt modulation, is improved through five vertical–vertical (VV) polarized Gaofen-3 (GF-3) SAR images acquired in Global Observation (GLO) and Wide ScanSAR (WSC) mode that were captured during the 2017 tropical cyclone (TC) season western Pacific Ocean. These are reprocessed to be Level-1B products collocated with wind fields from Regional Assimilation Prediction System – Typhoons...
The purpose of our work is to determine the feasibility and effectiveness retrieving sea surface wind speeds from C-band cross-polarization (herein vertical-horizontal, VH) Chinese Gaofen-3 (GF-3) SAR images in typhoons. In this study, we have collected three GF-3 acquired Global Observation (GLO) Wide ScanSAR (WSC) mode during summer 2017 China Sea, which includes typhoons Noru, Doksuri Talim. These were collocated with simulations at 0.12° grids a numeric model, called Regional...
The wind and wave derived from the scatterometer altimeter on board Chinese Haiyang-2B (HY-2B) satellite were systemically evaluated in this study. analysis of matchups between Advanced Scatterometer (ASCAT) winds HY-2B with speeds up to 25 m/s showed a 0.78 Root-Mean-Square Error (RMSE) 0.97 Correlation (COR), superior 1.2 RMSE 0.93 COR HY-2B. Simultaneously, significant heights (SWH) measured collocated measurements Jason-3 altimeter. Analysis calibration concluded that observations...

Ratoon rice, which refers to a second harvest of rice obtained from regenerated tillers originating the stubbles first harvested crop, plays an important role in both food security and agroecology while requiring minimal agricultural inputs. However, it is challenging accurately identify ratoon crops due similar spectral features with other cropping systems (e.g., double rice). Moreover, images high spatiotemporal resolution are essential since generally cultivated fragmented croplands...
Spaceborne Multi-Temporal Synthetic Aperture Radar (SAR) Interferometry (MT-InSAR) has been a valuable tool in mapping motion phenomena different scenarios. Recently, the capabilities of MT-InSAR for risk monitoring and preventive analysis heritage sites have increasingly exploited. Considering limitations conventional techniques, this study two-step Tomography-based Persistent Scatterers (PS) (Tomo-PSInSAR) approach is proposed ground deformation structural instabilities over Ancient City...
The monograph examines the historical, humanistic and ecological aspects of ancient urban trees, emphasizing their role as living monuments energy sources in environment. historical significance these trees is examined, tracing origin relationship to development cultural heritage. values are analyzed, cultural, spiritual educational contribution societies. In addition, study assesses environmental impact functions, including biodiversity support, climate regulation carbon sequestration....
This paper describes a study about the impact of earthquakes on debris flows with focus Great Wenchuan Earthquake 2008 in China. The land form, precipitation, and source material are three key factors for flow initiation surrounding area.
