TL;DR: The NASA Soil Moisture Active Passive (SMAP) mission has utilized a set of core validation sites as the primary methodology in assessing the soil moisture retrieval algorithm performance as mentioned in this paper.

TL;DR: In this paper, the authors examine how the nature of spatial variability affects hydrologic response over a range of scales using five field studies as examples, and they have emphasized how that characterization may change with the scale of hydrology model.

TL;DR: In this paper, the authors investigated the relationship between soil moisture patterns, lateral hillslope flow, and streamflow generation in a semi-arid, snowmelt-driven catchment.

TL;DR: In this paper, the authors evaluated the accuracy and precision of Hydra Probe measurements, established an electrical conductivity limit for Hydra probe measurements, and document effects of soil type and temperature, and relate these results to much more thoroughly studied relationships established for time domain reflectometry.

TL;DR: In this paper, the performance of the Hydra Probe soil water sensor with the following objectives: (i) quantify the inter-sensor variability, (ii) evaluate the applicability of data from two commonly used calibration methods, and (iii) develop and test two multi-soil calibration equations, one general, “default” calibration equation and a second calibration that incorporates the effects of soil properties.
