RISEstimating Spatial Sampling Errors in Coarse-Scale Soil Moisture Estimates Derived from Point-Scale Observations
Publisher: American Meteorological Society
Abstract: The validation of satellite surface soil moisture products requires comparisons between point-scale ground observations and footprint-scale (>100 km2) retrievals. In regions containing a limited number of measurement sites ...
Calibration of Noah Soil Hydraulic Property Parameters Using Surface Soil Moisture from SMOS and Basinwide In Situ Observations
Publisher: American Meteorological Society
Abstract: oil hydraulic properties (SHPs) control infiltration and redistribution of moisture in a soil column. The Noah land surface model (LSM) default simulation selects SHPs according to a location?s mapped soil texture class. ...
Comparison of In Situ Soil Moisture Measurements: An Examination of the Neutron and Dielectric Measurements within the Illinois Climate Network
Publisher: American Meteorological Society
Abstract: he continuity of soil moisture time series data is crucial for climatic research. Yet, a common problem for continuous data series is the changing of sensors, not only as replacements are necessary, but as technologies ...
The USDA Natural Resources Conservation Service Soil Climate Analysis Network (SCAN)
Publisher: American Meteorological Society
Abstract: Surface soil moisture plays an important role in the dynamics of land?atmosphere interactions and many current and upcoming models and satellite sensors. In situ data will be required to provide calibration and validation ...
Soil Moisture Model Calibration and Validation: An ARS Watershed on the South Fork Iowa River
Publisher: American Meteorological Society
Abstract: oil moisture monitoring with in situ technology is a time-consuming and costly endeavor for which a method of increasing the resolution of spatial estimates across in situ networks is necessary. Using a simple hydrologic ...
Different Rates of Soil Drying after Rainfall Are Observed by the SMOS Satellite and the South Fork in situ Soil Moisture Network
Publisher: American Meteorological Society
Abstract: oil moisture affects the spatial variation of land?atmosphere interactions through its influence on the balance of latent and sensible heat fluxes. Wetter soils are more prone to flooding because a smaller fraction of ...
The Contributions of Precipitation and Soil Moisture Observations to the Skill of Soil Moisture Estimates in a Land Data Assimilation System
Publisher: American Meteorological Society
Abstract: he contributions of precipitation and soil moisture observations to soil moisture skill in a land data assimilation system are assessed. Relative to baseline estimates from the Modern Era Retrospective-analysis for Research ...
Assimilation of Gridded GRACE Terrestrial Water Storage Estimates in the North American Land Data Assimilation System
Publisher: American Meteorological Society
Abstract: he objective of the North American Land Data Assimilation System (NLDAS) is to provide best-available estimates of near-surface meteorological conditions and soil hydrological status for the continental United States. To ...
Uncertainty of Reference Pixel Soil Moisture Averages Sampled at SMAP Core Validation Sites
Publisher: American Meteorological Society
Abstract: AbstractDespite extensive efforts to maximize ground coverage and improve upscaling functions within core validation sites (CVS) of the NASA Soil Moisture Active Passive (SMAP) mission, spatial averages of point-scale soil ...
An Intercomparison Study of Algorithms for Downscaling SMAP Radiometer Soil Moisture Retrievals
Publisher: American Meteorological Society
Abstract: In the past decade, a variety of algorithms have been introduced to downscale passive microwave soil moisture observations. Some exploit the soil moisture information from optical/thermal sensing of land surface temperature ...
