SWCTI: Surface Water Content Temperature Index for Assessment of Surface Soil Moisture Status [PDF]
Sensors, 2018 The vegetation supply water index (VSWI = NDVI/LST) is an effective metric estimating soil moisture in areas with moderate to dense vegetation cover. However, the normalized difference vegetation index (NDVI) exhibits a long water stress lag and the land

Global long term daily 1 km surface soil moisture dataset with physics informed machine learning [PDF]
Scientific Data, 2023 Although soil moisture is a key factor of hydrologic and climate applications, global continuous high resolution soil moisture datasets are still limited. Here we use physics-informed machine learning to generate a global, long-term, spatially continuous

Remote sensing and global databases for soil moisture estimation at different depths in the Pernambuco state, Northeast Brazil [PDF]
RBRH, 2022 The present study aimed to apply and assess an exponential filter that calculates the root-zone soil moisture using surface data from the soil moisture and ocean salinity (SMOS) satellite, as well as to assess soil moisture simulated in land-surface ...

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Soil moisture plays an important role in the global water cycle and has an important impact on energy fluxes at the land surface. It also defines the initial and boundary condition of terrestrial hydrological processes, including infiltration, runoff ...

Estimating root zone soil moisture using near-surface observations from SMOS [PDF]
Hydrology and Earth System Sciences, 2014 Satellite-derived soil moisture provides more spatially and temporally extensive data than in situ observations. However, satellites can only measure water in the top few centimeters of the soil. Root zone soil moisture is more important, particularly in

A Cuboid Model for Assessing Surface Soil Moisture [PDF]
Remote Sensing, 2019 This study proposes a cuboid model for soil moisture assessment. In the model, the three edges were the meteorological, soil, and vegetation feature parameters highly related to soil moisture, and the edge lengths represented the degree of influence of each feature parameter on soil moisture.

Operational assimilation of ASCAT surface soil wetness at the Met Office [PDF]
Hydrology and Earth System Sciences, 2011 Currently, no extensive, near real time, global soil moisture observation network exists. Therefore, the Met Office global soil moisture analysis scheme has instead used observations of screen temperature and humidity.

ADVANCES IN SOIL MOISTURE RETRIEVAL FROM NEAR-SURFACE MEASUREMENTS USING SATELLITE REMOTE SENSING [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 Soil moisture influences numerous environmental processes occurring over large spatial and temporal scales. It profoundly influences the hydrological and meteorological activity together with climate predictions and hazard analysis.
