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

, 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.

Introducing the SMAP L4 Products and Investigating the Spatio-Temporal Variability of Soil Moisture in Iran [PDF]

Nīvār, 2022
Background and objectives: Although estimation of soil surface moisture plays an important role in soil and water resources management, unfortunately, there is currently no national soil moisture monitoring network in Iran and the distribution of in situ

Temporal stability of soil moisture and radar backscatter observed by the advanced Synthetic Aperture Radar (ASAR) [PDF]

, 2008
The high spatio-temporal variability of soil moisture is the result of atmospheric forcing and redistribution processes related to terrain, soil, and vegetation characteristics.

Spatially and Temporally Complete Satellite Soil Moisture Data Based on a Data Assimilation Method

Remote Sensing, 2016
Multiple soil moisture products have been generated from data acquired by satellite. However, these satellite soil moisture products are not spatially or temporally complete, primarily due to track changes, radio-frequency interference, dense vegetation,

First attempt of global-scale assimilation of subdaily scale soil moisture estimates from CYGNSS and SMAP into a land surface model

Environmental Research Letters, 2021
Soil moisture performs a key function in the hydrologic process and understanding the global-scale water cycle. However, estimations of soil moisture taken from current sun-synchronous orbit satellites are limited in that they are neither spatially nor ...
