CAMEX-4 Hurricane Brightness Temperature Measurements

Advanced Microwave Precipitation Radiometer (AMPR) data captured brightness temperatures at four frequencies (10.7, 19.35, 37.1, and 85.5 GHz) during a month-long hurricane study. The Fourth Convection and Moisture Experiment (CAMEX-4) mission, led by NASA, collected this data from August 26 to September 24, 2001. Observations targeted hurricanes over the U.S., Gulf of Mexico, Caribbean, and Western Atlantic Ocean, coordinating with multiple aircraft and ground instruments.

Use Cases

• Calibrating satellite-based precipitation estimates by comparing 10.7, 19.35, 37.1, and 85.5 GHz brightness temperature signatures.
• Analyzing the structure of hurricanes and convective systems over both land and ocean surfaces.
• Validating atmospheric models by integrating brightness temperature data with coordinated radar and radiosonde observations.
• Studying the microwave emission properties of precipitation and cloud systems across a spectrum of frequencies.

Strengths

• Data was collected across four specific microwave frequencies (10.7, 19.35, 37.1, 85.5 GHz), enabling multi-spectral analysis.
• Observations are temporally focused on the 2001 hurricane season, covering a critical period from August 26 to September 24.

Limitations

• Key structural details like row count, file size, and specific column names are unavailable across all platforms.
• License information is inconsistently reported, listed as 'other-license-specified' on one platform and null on another.
