Soil Moisture‐Temperature Coupling in a Set of Land Surface Models [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2018
AbstractThe land surface controls the partitioning of water and energy fluxes and therefore plays a crucial role in the climate system. The coupling between soil moisture and air temperature, in particular, has been shown to affect the severity and occurrence of temperature extremes and heat waves.

A proposal for a SAR interferometric model of soil moisture [PDF]

open access: yes, 2012
Since long it is known that SAR interferometric observables are influenced by soil moisture variations, however there is a lack of scattering models that link interferometric observables and variations of the dielectric properties.

RETRIEVING SURFACE SOIL MOISTURE FROM MODIS AND AMSR-E DATA: A CASE STUDY IN TAIWAN [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Soil moisture is a key factor that controls the exchange of water between land surface evaporation and plant transpiration. Information on surface soil moisture variations in both time and spatial domains is important for numerous applications ...

Decomposing Dual Scale Soil Surface Roughness for Microwave Remote Sensing Applications [PDF]

open access: yes, 2012
Soil surface roughness, as investigated in this study, is decomposed in a dual scale process. Therefore, we investigated photogrammetrically acquired roughness information over different agricultural fields in the size of 6-22 m(2) and decomposed them ...

Estimating root zone soil moisture from surface soil moisture data and soil‐vegetation‐atmosphere transfer modeling [PDF]

open access: yesWater Resources Research, 1999
We studied the possibility of estimating root zone soil moisture through the combined use of a time series of observed surface soil moisture data and soil‐vegetation‐atmosphere transfer modeling. The analysis was based on the interactions between soil‐ biosphere‐atmosphere surface scheme and two data sets obtained from soybean crops in 1989 and 1990 ...

Mapping the Moisture of Surface Soil Using Landsat 8 Imagery (Case study: Suburb of Semnan City) [PDF]

open access: yesجغرافیا و پایداری محیط, 2018
Monitoring soil surface moisture, as a crucial factor in water and energy cycles, is of great importance in water and soil resource management. This important factor varies dramatically in time and space due to variability in soil characteristics ...

Soil Moisture Retrival Based on Sentinel-1 Imagery under Sparse Vegetation Coverage

open access: yesSensors, 2019
Soil moisture is an important aspect of heat transfer process and energy exchange between land-atmosphere systems, and it is a key link to the surface and groundwater circulation and land carbon cycles.

Coupled land surface and radiative transfer models for the analysis of passive microwave satellite observations [PDF]

open access: yes, 2012
Soil moisture is one of the key variables controlling the water and energy exchanges between Earth’s surface and the atmosphere. Therefore, remote sensing based soil moisture information has potential applications in many disciplines.

Coupled modelling of land surface microwave interactions using ENVISAT ASAR data [PDF]

open access: yes, 2004
In the last decades microwave remote sensing has proven its capability to provide valuable information about the land surface. New sensor generations as e.g. ENVISAT ASAR are capable to provide frequent imagery with an high information content.
