AMPR Brightness Temperature Data from CAMEX-2 Experiment

August 23-30, 1995, data from the Advanced Microwave Precipitation Radiometer (AMPR) deployed during the Convection and Moisture Experiment 2 (CAMEX-2). The dataset contains brightness temperature measurements collected at four microwave frequencies (10.7, 19.35, 37.1, and 85.5 GHz) over a defined geographic region. It is hosted by the NASA GHRC DAAC.

Use Cases

• Analyzing brightness temperature signatures at 10.7, 19.35, 37.1, and 85.5 GHz to study precipitation structure.
• Validating satellite-based microwave precipitation retrieval algorithms using calibrated airborne radiometer data.
• Investigating convection and moisture profiles during the CAMEX-2 field campaign within the 25.5°N-43°N, 83°W-70°W domain.
• Studying the relationship between multi-frequency microwave emissions and storm intensity for weather model improvement.

Strengths

• Data covers a precise 8-day time period (August 23-30, 1995) from a focused field experiment.
• Measurements are provided at four specific microwave frequencies (10.7, 19.35, 37.1, 85.5 GHz), enabling multi-spectral analysis.
• Geographic coverage is clearly defined between 25.5°N - 43°N latitude and 83°W - 70°W longitude.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date (1995-08 30 vs. 2026-03-13), suggesting potential metadata inconsistency.
• License is ambiguously listed as 'other-license-specified' or 'None', requiring user verification.
