SMEX04 Arizona Land Use Classification Data

SMEX04 Land Use Classification Data, Arizona, Version 1 provides land use classifications for modeling and scaling hydrologic variables as part of the Soil Moisture Experiment of 2004. The dataset is produced by the National Aeronautics and Space Administration. Support and documentation for this data set may be limited as it was provided solely by the Principal Investigator(s) and not further reviewed by NSIDC.

Use Cases

• Modeling hydrologic variables using land use classification data.
• Scaling soil moisture estimates based on land surface characteristics.
• Analyzing land cover for the Arizona region during the SMEX04 campaign.

Strengths

• Dataset is associated with a specific, documented scientific experiment (Soil Moisture Experiment of 2004).
• Cross-platform presence on Data.gov and NASA Earthdata signals its established use in the scientific community.

Limitations

• Critical metadata such as row count, column names, and file size are unknown across all sources.
• Sources conflict on the last updated date: Data.gov lists 2026-03-12, while NASA Earthdata lists 2004-08-30.
