SMEX02 Soil and Atmospheric Data from SCAN Station 2031, Ames, Iowa

SMEX02 Soil Climate Analysis Network (SCAN) Station 2031 provides sensor data from a site near Ames, Iowa, USA. The dataset is managed by the NSIDCV0 organization and has been updated on multiple platforms, with the most recent metadata update recorded in March 2026. It captures a range of environmental parameters relevant to soil and atmospheric science.

Use Cases

• Validating satellite-derived soil moisture estimates from the SMEX02 campaign using in-situ soil moisture water content measurements.
• Analyzing the relationship between atmospheric conditions like air temperature, humidity, and surface winds with soil temperature and moisture dynamics.
• Studying precipitation amount impacts on near-surface thermal properties, including land surface temperature and soil temperature.
• Modeling local water vapor indicators and solar radiation effects on frozen ground and soil conditions in a midwestern agricultural setting.

Strengths

• Data originates from a dedicated SCAN station (number 2031), part of a established network for soil climate analysis.
• Covers multiple earth science domains including soil moisture, atmospheric temperature, precipitation, and solar radiation, providing a multi-parameter view.
• Its presence on multiple authoritative platforms (nasa_earthdata, datagov) signals recognized importance and curation.

Limitations

• Critical facts like row count, file size, and specific column names are unavailable from all provided sources.
• Sources conflict on the 'last updated' date, with one listing 2002-08-31 and others listing 2026-03 12, creating uncertainty about data currency.
• The license is ambiguously listed as 'other-license-specified' or 'None', requiring further investigation for reuse.
