SMEX05: Soil Moisture Network Data for Iowa

SMEX05 Soil Moisture Network Data: Iowa, Version 1 contains in-situ soil moisture measurements from a field experiment conducted in Iowa, USA, in 2005. The dataset likely includes soil temperature and soil moisture water content readings. It is provided by the National Aeronautics and Space Administration but carries a notice that its documentation was not thoroughly reviewed by NSIDC.

Use Cases

• Validating satellite soil moisture retrievals based on in-situ ground measurements.
• Calibrating hydrological models using field-collected soil moisture and temperature data.
• Analyzing temporal soil moisture dynamics from the time-series network data.
• Studying land-atmosphere interactions during the SMEX05 field campaign.

Strengths

• Data originates from a controlled field experiment (Soil Moisture Experiment 2005).
• Dataset is hosted on multiple platforms (Data.gov, NASA Earthdata), indicating recognized importance.

Limitations

• Documentation is noted as being provided solely by the Principal Investigators and not reviewed/edited by NSIDC, which may limit support.
• Column names and structure are unknown across all sources, hindering precise usability assessment.
• There is a conflict in reported last updated dates: 2005-07-03 on NASA Earthdata vs. 2026-04-09 on Data.gov.
