Assessing the Potential of Combined SMAP and In-Situ Soil Moisture for Improving Streamflow Forecast

open access: yesHydrology, 2023
Soil moisture is an essential hydrological variable for a suite of hydrological applications. Its spatio-temporal variability can be estimated using satellite remote sensing (e.g., SMOS and SMAP) and in-situ measurements.

zhoylman/soil-moisture-validation: Optimizing Drought Assessment for Soil Moisture Deficits [PDF]

open access: yes, 2023
Accurate drought assessments are critical for mitigating the deleterious impacts of water scarcity on communities across the world. In many regions, deficits in soil moisture represent a key driver of drought conditions.

Parameter Sensitivity in LSMs: An Analysis Using Stochastic Soil Moisture Models and ELDAS Soil Parameters [PDF]

open access: yes, 2009
Integration of simulated and observed states through data assimilation as well as model evaluation requires a realistic representation of soil moisture in land surface models (LSMs).

Simultaneous thermal analysis of cationic, nonionic and anionic polyacrylamide

open access: yesHeliyon, 2019
Polyacrylamide (PAM) and its derivatives are the most commercially available water-soluble polymers and are frequently used for the production of clay-polymer composites.

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

open access: yesEnvironmental 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 ...

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.

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

open access: yes, 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.

Soil moisture initialization effects in the Indian monsoon system [PDF]

open access: yes, 2011
Towards the goal to understand the role of land-surface processes over the Indian sub-continent, a series of soil-moisture sensitivity simulations have been performed using a non-hydrostatic regional climate model COSMO-CLM.
