SMEX02 Regional Vegetation Sampling Data for Iowa

2002 vegetation parameters from the Soil Moisture Experiment 2002 (SMEX02) in Iowa. The dataset includes measurements of plant height, row spacing, stand density, and leaf area index (LAI). It is provided by the NSIDCV0 organization.

Use Cases

• Analyzing the relationship between leaf area index (LAI) and crop health.
• Modeling soil moisture interactions with plant height and stand density.
• Calibrating remote sensing data with ground-truth vegetation measurements from row spacing and density.
• Studying spatial variability of biophysical parameters in an agricultural region.

Strengths

• Provides specific, ground-measured vegetation parameters (plant height, row spacing, stand density, LAI) for validation.
• Data is associated with a defined scientific field campaign (Soil Moisture Experiment 2002).
• Dataset is hosted on multiple authoritative platforms (NASA EarthData, Data.gov), indicating recognized importance.

Limitations

• Critical metadata conflicts exist: the reported last update date differs significantly between sources (2002-07-28 vs. 2026-03 12).
• Key technical details are unknown, including row count, file size, and the complete set of column names.
• The specific license terms under 'other-license-specified' are not detailed.
