Mapping surface soil moisture Gourma mesoscale ENVISAT ASAR
2011/3/15
The potentialities of ENVISAT ASAR (Advanced Synthetic Aperture Radar) multi-angle data for mapping surface soil moisture (SSM) in Sahelian rangelands are investigated at medium scale (30 000 km2). Th...
Desert shrub stemflow and its significance in soil moisture replenishment
Desert shrub stemflow soil moisture replenishment
2011/3/15
Stemflow of xerophytic shrubs represents a significant component of water replenishment to the soil-root system influencing water utilization of plant roots at the stand scale, especially in water sca...
Cross-evaluation of modelled and remotely sensed surface soil moisture with in situ data in southwestern France
surface soil moisture situ data southwestern France
2010/12/22
The SMOSMANIA soil moisture network in Southwestern France is used to evaluate modelled and remotely sensed soil moisture products. The surface soil moisture (SSM) measured in situ at 5 cm permits to ...

The role and the importance of soil moisture for meteorological, agricultural and hydrological applications is widely known. Remote sensing offers the unique capability to monitor soil moisture over l...
Relating surface backscatter response from TRMM precipitation radar to soil moisture:results over a semi-arid region
surface backscatter response TRMM precipitation radar soil moisture semi-arid region
2010/3/5
The Tropical Rainfall Measuring Mission (TRMM) carries aboard the Precipitation Radar (TRMMPR) that measures the backscatter (σ°) of the surface. σ° is sensitive to surface soil moisture and vegetatio...
Use of soil moisture dynamics and patterns at different spatio-temporal scales for the investigation of subsurface flow processes
soil moisture dynamics subsurface flow processes
2009/7/22
Spatial patterns as well as temporal dynamics of soil moisture have a major influence on runoff generation. The investigation of these dynamics and patterns can thus yield valuable information on hydr...
Spatial and temporal predictions of soil moisture patterns and evaporative losses using TOPMODEL and the GASFLUX model for an Alaskan catchment
soil moisture patterns evaporative losses Alaskan catchment
2009/5/27
By using topographic indices as derived from a Digital Terrain Models (DTM), it is possible to represent the heterogeneity within a landscape. This heterogeneity can reflect both long term evolutiona...
Soil moisture gradients and controls on a southern Appalachian hillslope from drought through recharge
Soil moisture watersheds
2009/5/27
Soil moisture gradients along hillslopes in humid watersheds, although indicated by vegetation gradients and by studies using models, have been difficult to confirm empirically. While soil properties...
The role of spatial variability of soil moisture for modelling surface runoff generation at the small catchment scale

2009/5/27
A Bayesian approach is described for dealing with the problem of infilling and generating stochastic flow sequences using rainfall data to guide the flow generation process, and including bounded (ce...
A fast TDR-inversion technique for the reconstruction of spatial soil moisture content
soil moisture TDR-inversion technique
2009/5/18
Spatial moisture distribution in natural soil or other material is a valuably information for many applications. Standard measurement techniques give only mean or punctual results. Therefore a new inv...

A simplified, vertically-averaged model of soil moisture interpreted at the daily time scale and forced by a stochastic process of instantaneous rainfall events is compared with a vertically-averaged ...
Estimating spatial mean root-zone soil moisture from point-scale observations
soil moisture point-scale spatial mean
2009/5/15
Root zone soil moisture is a key variable in many land surface hydrology models. Often, however, there is a mismatch in the spatial scales at which models simulate soil moisture and at which soil moi...
