    Soil moisture variability on the landscape as a function of land use: implication for remote sensing of surface soil moisture Abstract: Knowledge of the spatial and temporal distribution of soil moisture under a variety of landscapes and soil conditions is essential for the proper management and utilization of available water.   Baisha Weng, Wuxia Bi, Zhixuan Zhao, Ting Xu, Dengming Yan, Spatial and temporal variability of soil moisture based on multifractal analysis, Arabian Journal of Geosciences, /s, 11, 16, ().

      The temporal and spatial variation of soil moisture is an important index to evaluate soil water content. In this paper, the variation of soil moisture in space and time is analyzed by time series analysis and geostatistical methods using Internet of things (IOT) data in order to provide a theoretical basis for the rational arrangement and.   Spatial and Temporal Variability of Root-Zone Soil Moisture Acquired From Hydrologic Modeling and AirMOSS P-Band Radar Abstract: The accurate estimation of grid-scale fluxes of water, energy, and carbon requires consideration of subgrid spatial variability in root-zone soil moisture .

    Spatial and temporal variability of soil moisture: 6 years survey of SMOS data and in-situ soil moisture measurements in Poland. Mateusz Łukowski, Wojciech Marczewski, Bogusław Usowicz, Jerzy Usowicz, Jan Słomiński, Edyta Rojek, Radosław Szlązak, Łukasz Gluba, Joanna Sagan 🔲🔲. the spatial variability of surface soil moisture at various scales. Famiglietti et al. () argued that it is necessary to study this variability in order to better understand the nature of soil moisture within a satellite pixel (footprint). To this end, the Southern Great Plains (SGP97) hydrology experiment.

Get this from a library. Spatial and temporal variability of soil moisture in Oklahoma. [Tracy L DeLiberty]. Husain Akbari Majdar, Mehdi Vafakhah, Mohammad Sharifikia, Ardavan Ghorbani, Spatial and temporal variability of soil moisture in relation with topographic and meteorological factors in south of Ardabil Province, Iran, Environmental Monitoring and Assessment, /s,9, ().Cited by:   The objective of this study is to establish a WSN-based monitoring system of soil moisture, and analyze the temporal and spatial variability of soil moisture with high temporal resolution for the realization of variable irrigation.

Materials and methods Architecture of soil moisture real-time monitoring systemCited by: Using a hydrologic model to estimate daily soil moisture at evaluation locations over a year period, the spatial variability and persistence of soil moisture across Oklahoma is examined.

Although soil variability is clearly not the only driver of water content variability (Famiglietti et al., b) nevertheless it may represent a significant source for determining meaningful quantities, like the standard deviation of water content (e.g., Chen et al., ; Clapp et al., ; Fatichi et al., ), and hence it is worth to be Cited by: 9.

during this 30 year period and the temporal scale of soil moisture variability for Oklahoma. On average, the soil moisture conditions in both winter and spring in Oklahoma are about 70% of field capacity and decrease to below 30% during the summer.

Thus, the seasonal cycle is pronounced, although periods of wetter and drier conditions are evident. Spatial and temporal variability of the soil-plant-atmosphere system is an important tool for the statistical analysis of several sets of data collected in the field.

The techniques here seen allow. Soil moisture is closely related to the hydrosphere, atmosphere, and biosphere, which makes it one of the most significant climate variables.

Using data from the National Environmental Forecasting Center (NCEP), this paper analyzes the temporal and spatial characteristics of soil moisture at a depth of 0–10 cm in China for the period of to Further analysis demonstrated that, at shallow soil depths (5 and 25 cm), the spatial variability of soil moisture across Oklahoma was most homogeneous during the winter and spring periods and most heterogeneous during the summer and autumn periods.

Conversely, at greater depths (60 and 75 cm), soil moisture was most heterogeneous during the winter. In contrast, selecting N = days means that anomalies are calculated relative to a fixed soil moisture mean across the entire seasonal cycle.

Recreating Fig. 2 for N = days increases the RMSE from to m 3 m −3, suggesting that TC works better when variations in soil moisture climatology are taken into account.

The characterization of temporal and spatial variability of soil moisture is highly relevant for understanding the many hydrological processes, to model the processes better and to apply them to conservation planning. Considerable variability in space and time coupled with inadequate and uneven distribution of irrigation water results in uneven yield in an area Spatial and temporal variability.

In this section, previous studies on spatial variability of near surface soil moisture content, θ, at small catchment scale are reviewed, with particular emphasis to the more recent each study, Table 1 reports some synthetic characteristics of the area investigated, the statistical properties of the soil moisture samplings and the measurement method.

predictions. Additionally, soil moisture variability may differ by spatial extent or scale [Crow and Wood, ]. [4] The objective of this study is to identify common patterns among soil moisture statistics across a variety of landscapes.

Specifically, the relationships between mean soil moisture and spatial variability of soil moisture mea. Keywords: Soil Moisture, Spatial & Temporal Variability, Kriging 1. Introduction Spatially and temporally varying soil moisture is being increasingly used as input to hydrological and meteoro- logical models.

Knowledge of spatial and temporal vari- ability of field soil helps in characterization of the soil. These data are routinely used by researchers in hydrology, meteorology, climatology, remote sensing, and related disciplines for a diverse array of studies, including research on soil moisture spatial and temporal variability (Illston et al.

; Lakhankar et al. ), land–atmosphere interactions (Godfrey and Stensrud ), groundwater. Abstract [1] Feedback between soil moisture and precipitation influence climate variability in semiarid regions.

However, serious concerns exist about the ability of coarse-scale global atmospheric models to depict one key aspect of the feedback loop, namely the sensitivity of daytime convection to soil moisture. The spatiotemporal variability in soil moisture can be affected by different environmental factors at varying spatiotemporal scales.

For instance, depending on the spatial scale of interest, the factors that affect soil moisture spatial variability may vary noticeably, including factors at local scales and meteorological forcings at regional scales (Seneviratne et al.

The temporal variability in soil moisture for forest ecosystems reflect the continuous drying during the growing season.

This is more apparent toward the end of the growing season due to decrease in precipitation amounts. It was intermediate variability in the soil sample.
