Drought as a complex natural hazard encompassing comprehensive information on the occurrence and development of drought using single variable alone is difficult. In present study, composite multivariate index (CMDI) was developed based copula combining three univariate indices (standardized precipitation [SPI], standardized runoff [SRI], water storage deficit [WSDI]) four timescales (monthly, quarterly, semi-annually, annually). The new combines terrestrial storage, precipitation, to capture...
Soil moisture (SM) is an indispensable variable in drought monitoring and weather forecast. L-band found to be the most suitable band for retrieving surface SM. Here, we evaluate two passive microwave SM products Moisture Active Passive (SMAP) Ocean Salinity (SMOS) Inner Mongolia. The collected in-situ data from 24 measured sites triple collocation (TC) analysis method (using Global Land Data Assimilation System (GLDAS) Noah Advanced Scatterometer (ASCAT) as a reference dataset) are used...
Ten major river basins in China. The spatial and temporal distribution of terrestrial water storage (TWS) China is significantly affected by global climate change increased human activity. In this study, we analyzed the variability TWS ten Chinese based on data Gravity Recovery Climate Experiment (GRACE). To discuss driving force TWS, assessed relative contributions time lags precipitation (P), evapotranspiration (ET), runoff (R) to using Spearman correlation analysis partial least squares...
Currently, there is an absence of exhaustive elucidation regarding the long-term spatiotemporal characteristics meteorological droughts in China. Previous studies have predominantly fixated on lower-dimensional (temporal or spatial) facets drought events, overlooking critical details. This paper proposes integrated processing framework that employs a three-dimensional clustering algorithm to discern events and quantifies patterns dynamic attributes China's during 1950–2021 from perspective...
Soil moisture (SM) plays an essential role in the hydrological cycle, drought monitoring, and water resources management. However, passive microwave remote sensing products offer coarse spatial resolutions (approximately 25–40 km), greatly limiting their applications. In this study, we considered vegetation memory increased amount of data by spatiotemporal fusion, integrated lagged index fusion as model inputs, downscaled resolution SMAP SM using Random Forest (RF) well multi-source data....
When using HBase to store tiles of remote sensing images, the spatial position a tile is often used as first part tile's rowkey so that with high correlations are stored close together improve query efficiency. We refer this storage method Geo-First model. However, models have two problems: load between nodes unbalanced, and accumulation time-series images has negative impact on Considering these problems, we proposed for storing based Google S2 HBase. In our method, strategies adopted...
Fracture energy, as an important characteristic parameter of the fracture properties materials, has been extensively studied by scholars. However, less research carried out on ubiquitiformal energy and main method used scholars is uniaxial tensile test. In this paper, based previous research, first Brazilian splitting test was to study crack extension slate granite, complexity rock material were obtained. The heterogeneity then characterized Weibull statistical distribution, cohesive model...
In the era of rapid data expansion and computer technology development, discrete storage, multiband push fuzzy query remote sensing management methods are no longer suitable for analysis needs users, including long time series, global regions multidata fusion. After analyzing traditional techniques, this paper discusses existing achievements development trends current technologies. This aims to solve problem sharing difficulties organizational inconsistency caused by use different formats...
Soil moisture (SM) plays an essential role in the hydrological cycle, drought monitoring, agricultural production, and water resources management. However, SM products of passive microwave remote sensing have coarse spatial resolutions (approximately 25-40km), which may largely limit applications hydrology agriculture. In this study, ESTARFM Random Forest(RF) models, along with multi-source data, were used jointly to generate downscaled at 1 km resolution. First, improve spatiotemporal...
Abstract To achieve the “carbon peak” goal, green and low-carbon energy development is key. The utilization of geothermal resources deep carbonate wells in China are analyzed. Based on principle chemical reaction between hydrochloric acid main components rock, four rock samples from were dissolved with 15% 20% acid, respectively. comparison showed that was more economical effective. percolation capacity dissolution fractures tested through experiments, optimal amount solution determined to...

Summary Rock physics model is the key tool for S-wave velocity prediction and rock analysis. Since we can’t obtain shear of high precision through classical Xu-White in condition multi-mineral, this paper modified by introduce multi-mineral calculating elastic properties matrix rock. In addition, based on self-consistent approximation(SCA) Gassmann’s theory, build up workflow, method, mineral composition pores can be assumed to particles certain shapes. The practical study Bohaibay basin...
