Colorado Soil Moisture Point Measurements from CLPX-Ground

Northern Colorado soil moisture data provides in-situ point measurements from three 25-km by 25-km Meso-cell Study Areas: Fraser, North Park, and Rabbit Ears. The dataset was produced by the National Aeronautics and Space Administration. A conflict exists regarding its last update, with one source listing 2003 and another listing a future date of 2026.

Use Cases

• Validating satellite soil moisture retrievals using precise in-situ point measurements.
• Analyzing spatial variability of soil water content across three distinct Colorado study areas.
• Supporting land surface and hydrological modeling for the Cold Land Processes Experiment (CLPX).

Strengths

• Provides ground-truth data from three specific 25-km by 25-km Meso-cell Study Areas in Colorado.
• Originates from the authoritative National Aeronautics and Space Administration.

Limitations

• Critical metadata conflict: last updated date is listed as both 2003-04-30 and a future date of 2026-03 13.
• Column names, row counts, and exact file sizes are unknown across all sources.
