SMEX03 AMSR-E: Daily Soil Moisture and Brightness Temperatures, Georgia

Georgia, USA, is the focus of this Level-3 daily gridded dataset containing surface soil moisture and vegetation/roughness water content measurements from the Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E). The data includes derived brightness temperatures, providing a time series for land surface analysis. Documentation was provided solely by the Principal Investigator(s) and was not further developed or edited by NSIDC, which may limit support.

Use Cases

• Monitoring agricultural drought conditions based on daily surface soil moisture measurements.
• Validating hydrological and land surface models using gridded brightness temperature data.
• Analyzing vegetation water content and surface roughness impacts on microwave signals.
• Studying temporal trends in land surface variables for a specific geographic region.

Strengths

• Data originates from a NASA satellite instrument (AMSR-E), indicating a standardized collection method.
• Provides daily Level-3 gridded products, offering consistent spatial and temporal resolution.

Limitations

• Documentation support is explicitly limited as it was not reviewed or edited by the hosting data center (NSIDC).
• Key metadata conflicts: 'last updated' dates differ significantly between sources (2003 vs. 2026).
• Column names, dataset size, and row counts are unspecified across all platform entries.
