Web82 root zone soil moisture maps generated by the remote sensing algorithm SEBAL. This 83 study is novel since previous multi-scaling studies on soil moisture dealt with soil 84 moisture in the top 0-5 cm of the soil (Jackson, Schumgge, and Engman 1997; Jackson 85 and O’Neill 1986) while our study deals with root zone soil moisture. Web30 de abr. de 1999 · The spatial scale of soil moisture measurements is often inconsistent with the scale at which soil moisture predictions are needed. Consequently a change of …
On the scaling characteristics of observed and simulated spatial …
WebThe spatial structure of soil moisture exhibited linearity in the log-log dependency of the variance versus scale-factor, up to a scale factor of -2.6 (6100 m X 6100 m) irrespective of wet and dry conditions, whereas dry fields reflect nonlinear (multi-scaling) behavior Web19 de jan. de 2008 · The relationship of soil moisture standard deviation, skewness and the coefficient of variation versus mean moisture content was explored at six distinct extent scales, ranging from 2.5 m to 50 km. Results showed that … black and decker circular saw cordless
Spatial Scaling - UC Davis
WebIn this study, spatial variations in soil moisture at depths of 0-6 m on seven hillslopes of China's Loess Plateau planted with korshinsk peashrub were analyzed based on soil moisture observations. The objective of this study was to compare the spatial patterns in soil moisture in shallow and deep soil layers at the hillslope scale under the influence … Web1 de jan. de 2008 · The normalized difference vegetation index (NDVI), rainfall, air temperature (AT) and soil moisture (SM) are used as independent variables and yield … Web18 de jun. de 2006 · Spatial heterogeneity in precipitation and vegetation exert significant control on scaling properties, especially in water-limited ecosystems. Computational results indicate that relationships between spatially averaged variables controlling soil-moisture dynamics are non-unique at larger averaging scales, even when unique, non-hysteretic … black and decker circular saws
