CAMEX-3 AMPR: Hurricane Microwave Brightness Temperatures

AMPR data from the CAMEX-3 mission captured microwave brightness temperatures at four specific frequencies (10.7, 19.35, 37.1, and 85.5 GHz) to study hurricanes. This dataset was collected from August 8 to September 27, 1998, over the U.S. Gulf of America, Caribbean, and Western Atlantic Ocean. Its collection was coordinated with multiple aircraft and ground-based instruments including research-quality radar and radiosondes.

Use Cases

• Analyzing hurricane structure and intensity based on multi-frequency brightness temperature signatures.
• Validating satellite-based precipitation retrieval algorithms using coordinated aircraft and ground radar data.
• Studying the relationship between microwave emissions and convective processes over both ocean and land.

Strengths

• Provides multi-frequency microwave observations at four specific frequencies (10.7, 19.35, 37.1, 85.5 GHz).
• Data collection was coordinated with a suite of other research instruments during the focused CAMEX-3 mission.

Limitations

• Key metadata such as column names, row counts, and file sizes are consistently listed as 'unknown' or 'None' across platforms.
• The dataset's last update date conflicts between sources, with one showing 1998 and another showing a future date of 2026.
