AMPR Jacksonville Brightness Temperature Data for Microwave Radiometer Validation

AMPR JACKSONVILLE BRIGHTNESS TEMPERATURE (TB) contains microwave radiometer data collected during an instrument validation mission in Jacksonville, Florida. The dataset was gathered by the Advanced Microwave Precipitation Radiometer (AMPR) at four frequencies (10.7, 19.35, 37.1, and 85.5 GHz) to study convection over land and ocean. It is hosted by the GHRC_DAAC and covers a specific ten-day period in October 1990.

Use Cases

• Validating brightness temperature measurements from the AMPR instrument against ground truth.
• Analyzing convective storm properties over mixed land-ocean surfaces using multi-frequency microwave data.
• Calibrating radiometer models using clear, dry atmospheric columns measured over the ocean.
• Studying the microwave spectral signature of precipitation events from a historical airborne campaign.

Strengths

• Data was collected at four specific microwave frequencies (10.7, 19.35, 37.1, 85.5 GHz), enabling multi-spectral analysis.
• The dataset's purpose is clearly defined for instrument validation and study of convection over land and ocean.
• Its presence on multiple official platforms (NASA Earthdata and Data.gov) signals recognized importance and curation.

Limitations

• Core dataset specifications like row count, file size, and complete column names are unavailable from all sources.
• There is a conflict in the 'last updated' metadata, with one source reporting 1990 and others reporting 2026.
• The specific license terms under 'other-license-specified' are not detailed.
