AMPR Brightness Temperature Data for KWAJEX 1999

Four microwave frequency channels (10.7, 19.35, 37.1, and 85.5 GHz) were used by the Advanced Microwave Precipitation Radiometer (AMPR) to collect brightness temperature data. The data were gathered during the First Kwajelein Experiment (KWAJEX) from 30 July to 14 September 1999, providing ground validation for the Tropical Rainfall Measuring Mission (TRMM). The dataset was produced by the National Aeronautics and Space Administration.

Use Cases

• Validate and calibrate satellite-based precipitation measurements based on the ground-based microwave radiometer data.
• Study the microphysical properties of rain clouds based on multi-frequency brightness temperature observations.
• Develop or test algorithms for retrieving precipitation rates from passive microwave data.
• Analyze temporal evolution of convective systems during the KWAJEX field campaign.

Strengths

• Data collected at four specific microwave frequencies (10.7, 19.35, 37.1, 85.5 GHz) suited for precipitation studies.
• Clear temporal coverage from 30 July to 14 September 1999.
• Produced by the authoritative National Aeronautics and Space Administration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF, GIF, and HTML formats, which may require conversion for computational analysis.
