SMEX03 Regional Ground Soil Moisture Data for Oklahoma

SMEX03 Regional Ground Soil Moisture Data: Oklahoma, Version 1 contains soil moisture measurements and field averages for the Oklahoma study region. The dataset was created by NSIDCV0 as part of the Soil Moisture Experiment 2003 (SMEX03). It provides in-situ ground measurements for validating satellite-derived soil moisture data.

Use Cases

• Validating satellite soil moisture retrievals using ground-measured soil moisture water content.
• Analyzing the relationship between soil temperature and soil moisture dynamics.
• Studying soil properties, such as soil bulk density, for hydrological modeling.
• Investigating spatial and temporal patterns of surface conditions during the SMEX03 field campaign.

Strengths

• Dataset is part of a structured NASA field experiment (Soil Moisture Experiment 2003), ensuring methodological rigor.
• Includes summary files with field averages, facilitating regional analysis.
• Available on multiple authoritative platforms (NASA Earthdata and Data.gov), indicating reliability and importance.

Limitations

• Specific row counts, column names, and dataset size are not provided by any source, limiting precise assessment.
• Conflicting last updated dates exist: one source shows 2003-07-17, while others show 2026-03-12, creating uncertainty about metadata maintenance.
