AMPR Brightness Temperature Data from CaPE Experiment

July 21 to August 16, 1991 data from the Advanced Microwave Precipitation Radiometer deployed during the Convection and Precipitation/Electrification Experiment. The dataset contains brightness temperature measurements at four microwave frequencies (10.7, 19.35, 37.1, and 85.5 GHz) over central Florida. It is hosted by the NASA GHRC DAAC.

Use Cases

• Analyzing brightness temperature signatures across four microwave frequencies (10.7, 19.35, 37.1, 85.5 GHz) to study cloud and precipitation properties.
• Validating satellite-based microwave radiometer retrievals using high-resolution airborne measurements from a specific field campaign.
• Investigating the relationship between convective storm electrification and microwave brightness temperatures during the CaPE experiment.
• Studying spatial patterns of atmospheric phenomena within the defined Florida region (43°N to 25.5°N, 86°W to 69°W).

Strengths

• Provides temporally focused data from a 27-day intensive field campaign in July-August 1991.
• Captures multi-frequency microwave brightness temperatures, a key variable for atmospheric remote sensing.
• Cross-platform presence on NASA Earthdata and Data.gov indicates recognized importance and curation.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date (1991-08-16 vs. 2026-03 -13), creating uncertainty about metadata maintenance.
