LPRM_AMSRE_A_SOILM3: Daily Global Soil Moisture from AMSR-E

From June 2002 to October 2011, this dataset provides daily, gridded land surface parameters derived from the AMSR-E satellite's passive microwave observations. It includes surface soil moisture, land skin temperature, and vegetation water content, processed using the Land Parameter Retrieval Model (LPRM). The data is provided at a 25 km resolution for daytime (ascending) passes.

Use Cases

• Monitoring drought conditions based on daily surface soil moisture retrievals.
• Validating land surface models using concurrent measurements of soil moisture, temperature, and vegetation water content.
• Analyzing long-term trends in global hydrological variables over the 2002-2011 period.
• Studying land-atmosphere interactions using the derived skin temperature and soil moisture data.

Strengths

• Provides a consistent, multi-year time series from June 2002 to October 2011.
• Derives three key land surface parameters (soil moisture, temperature, vegetation water content) simultaneously from a single sensor using a validated physical model (LPRM).
• Has a cross-platform presence on NASA Earthdata and Data.gov, indicating established use and validation.

Limitations

• Data collection ceased in October 2011 due to a satellite antenna failure, limiting temporal coverage.
• Spatial resolution is coarse (25 km), which may not be suitable for regional or field-scale studies.
• Metadata for specific columns, file sizes, and row counts is unavailable across all sources.
