Southwestern U.S. Soil Water Depth and Meteorological Data for Multiscalar Index Analysis

Site-specific daily matric potential values for soil depths from 0 to 200 centimeters. The dataset cross-references soil hydraulic parameters and coordinates with precipitation and water deficit data for calculating SPI and SPEI indices. It was created by Trevor T. McKellar of the University of Arizona.

Use Cases

• Modeling soil water depth and matric potential based on site-specific soil texture and hydraulic parameters.
• Calculating Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI) based on provided precipitation and water deficit data.
• Analyzing correlations between daily meteorological values and soil moisture conditions at specific sites.
• Validating hydrological models using cross-referenced site soil data, including latitude and longitude coordinates.

Strengths

• Includes daily matric potential values for a defined soil depth interval of 0-200cm.
• Cross-references multiple data sources: soil parameters, coordinates, precipitation, and water deficit.
• Data is structured for calculating standardized drought indices (SPI and SPEI).

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.
