Australian Root Zone Soil Moisture: Assimilation of Remote Sensing Observations
Knowledge of temporal and spatial variation in root zone soil moisture content across Australia is vital for a wide range of environmental and socio-economic activities. However, such information is not currently available, due to an inability to monitor with ground-based point measurement techniques at an appropriate spatial resolution, and the uncertainty associated with land surface model pr...
متن کاملA minimalist probabilistic description of root zone soil water
The probabilistic response of depth-integrated soil water to given climatic forcing can be described readily using an existing supply-demand-storage model. An apparently complex interaction of numerous soil, climate, and plant controls can be reduced to a relatively simple expression for the equilibrium probability density function of soil water as a function of only two dimensionless parameter...
متن کاملMapping Root Zone Soil Moisture Using Remotely Sensed Optical Imagery
Field-based soil moisture measurements are cumbersome. Remote sensing techniques based on active or passive microwave data have limitations. This paper presents and validates a new method based on land surface energy balances using remotely sensed optical data ~including thermal infrared!, which allows field and landscape-scale mapping of soil moisture depth-averaged through the root zone of ex...
متن کاملRoot Zone Soil Moisture Assessment Using Remote Sensing and Vadose Zone Modeling
Soil moisture is an important hydrologic state variable critical to successful hydroclimatic and environmental predictions. Soil moisture varies both in space and time because of spatio-temporal variations in precipitation, soil properties, topographic features, and vegetation characteristics. In recent years, airand space-borne remote sensing campaigns have successfully demonstrated the use of...
متن کاملeffect of partial root-zone drying on the pattern of spatiotemporal changes of soil temperature and soil electrical conductivity in maize root-zone
in this study, the pattern of changes in the values of soil electrical conductivity (ec) and soil temperature (t) under full irrigation treatment (fi) as compared with prd75 and prd55 treatments (partial root-zone drying which received 75 % and 55% water of fi at each irrigation event) was investigated in 1389 on a maize filed in sari university of agricultural sciences and natural resources. r...
