TCSP AMPR Brightness Temperature Measurements from 2005 Campaign

Four microwave frequencies (10.7, 19.35, 37.1, and 85.5 GHz) were used to collect brightness temperature data from July 5 to July 27, 2005. The Advanced Microwave Precipitation Radiometer (AMPR) on a NASA aircraft provided high-resolution passive microwave imagery. This dataset is managed by the Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC).

Use Cases

• Analyzing passive microwave signatures for precipitation and cloud system studies using the four frequency channels.
• Calibrating or validating satellite-based microwave radiometer data with high-resolution airborne measurements.
• Investigating the relationship between brightness temperature at 85.5 GHz and ice scattering signatures in convective systems.
• Studying surface emission properties over ocean and land using the lower frequency 10.7 and 19.35 GHz data.

Strengths

• Data collected at four specific microwave frequencies (10.7, 19.35, 37.1, 85.5 GHz) unique to NASA aircraft instrumentation.
• Provides high spatial and temporal resolution imagery from an airborne platform during a focused 23-day campaign.

Limitations

• Specific row count, file size, and column names are not provided by any source.
• Sources conflict on the last updated date: one states 2005-07-27, another states 2026-03-12.
