Quantifying the linkage between SMAP soil moisture and fully-integrated hydrologic simulat

From March 31, 2015 to December 31, 2017, this dataset provides soil moisture and groundwater storage data for the South Nation Watershed in eastern Canada. It combines high-resolution simulations from the HydroGeoSphere model with near-surface soil moisture and Soil Water Index derived from the SMAP satellite. The data was compiled by Aruna Kumar Nayak of the University of Toronto.

Use Cases

• Validate integrated hydrological model outputs based on satellite-derived soil moisture data.
• Analyze the linkage between surface soil moisture and deeper groundwater storage based on multi-layer soil moisture data.
• Study temporal dynamics of water storage in a watershed based on the 2015-2017 time series.
• Compare simulated soil moisture from HydroGeoSphere with SMAP satellite observations.

Strengths

• Data covers a specific 2.75-year period from March 2015 to December 2017.
• Integrates two distinct data sources: high-resolution model simulations and 9 km resolution satellite data.
• Provides soil moisture data over multiple soil layers between 0 and 100 cm depth.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
