CAMEX-4 Airborne Microwave Radiometer Data for Hurricane Study

August 8 to September 24, 2001 data from the Conically-Scanning Two-look Airborne Radiometer (C-STAR) deployed during the Fourth Convection and Moisture Experiment (CAMEX-4). The dataset contains 37GHz microwave brightness temperature measurements collected by aircraft to study hurricanes over the U.S., Gulf of Mexico, Caribbean, and Western Atlantic Ocean. It was produced by the Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC).

Use Cases

• Analyzing hurricane structure and intensity using 37GHz brightness temperature measurements.
• Studying atmospheric convection and moisture profiles during tropical cyclones.
• Validating satellite-based microwave observations with calibrated airborne data.
• Integrating radiometer data with concurrent CAMEX-4 radar and lightning measurements for multi-sensor analysis.

Strengths

• Data covers a focused 48-day campaign during the 2001 Atlantic hurricane season.
• Measurements are from a research-quality airborne instrument (C-STAR) at a specific 37GHz frequency.
• Dataset is hosted by NASA's GHRC DAAC and appears on multiple authoritative platforms, indicating curation.

Limitations

• Specific row count, file size, and complete column schema are not provided by any source.
• Conflicting 'last updated' metadata: one source states 2001-09-24, while others state 2026 03-13.
