AMPR Brightness Temperature Data from CAMEX-1 Campaign

Microwave radiometer brightness temperature measurements were collected during the Convection and Moisture Experiment (CAMEX-1) campaign. The dataset covers a ten-day period from September 26 to October 5, 1993, over a region between 25.5N-43N latitude and 70W-83W longitude. Data originates from the Advanced Microwave Precipitation Radiometer (AMPR) instrument, managed by the GHRC DAAC.

Use Cases

• Analyzing brightness temperature at four microwave frequencies (10.7, 19.35, 37.1, 85.5 GHz) to study precipitation processes.
• Validating satellite-based microwave retrievals using calibrated airborne instrument data.
• Investigating the spatial and temporal structure of convection during the CAMEX-1 field campaign.
• Studying the relationship between microwave brightness temperature and atmospheric moisture profiles.

Strengths

• Data is collected at four specific microwave frequencies, enabling multi-spectral analysis.
• Geographic and temporal coverage is precisely defined for the CAMEX-1 campaign period and region.
• The dataset's presence across multiple authoritative platforms (NASA EarthData, Data.gov) signals its established use.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date, reporting both 1993-10-05 and 2026-03 13.
