AMSR Unified: Global Ocean Water Vapor, Cloud Liquid, and Wind Speeds

A unified satellite data record from the AMSR-E and AMSR2 instruments, resampled and intercalibrated by the Japan Aerospace Exploration Agency (JAXA). It reports integrated water vapor, cloud liquid water content, and 10-meter sea surface wind speeds globally. The dataset is produced by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling atmospheric moisture transport based on integrated water vapor content.
• Analyzing ocean-atmosphere coupling using 10-meter sea surface wind speeds.
• Studying cloud formation and microphysics based on cloud liquid water content.
• Validating climate and weather models with unified, intercalibrated satellite observations.

Strengths

• Data is intercalibrated to create a unified record from two satellite instruments (AMSR-E and AMSR2).
• Derived from brightness temperature observations resampled by the Japan Aerospace Exploration Agency (JAXA).
• Includes ancillary files for product history, quality assessment, and metadata.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data volume are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
