AMPR Brightness Temperature Data from TOGA COARE Campaign

AMPR brightness temperature data were collected at four microwave frequencies (10.7, 19.35, 37.1, and 85.5 GHz) during the TOGA COARE intensive observation period. The dataset covers a 45-day period from January 12 to February 25, 1993, over a geographic domain from the equator to 21 S latitude and 145 E to 161 E longitude. It was produced by the GHRC DAAC as part of atmospheric measurements for the Tropical Ocean Global Atmosphere-Coupled Ocean Atmosphere Response Experiment.

Use Cases

• Analyzing spatial and temporal patterns of brightness temperature at 10.7, 19.35, 37.1, and 85.5 GHz frequencies.
• Studying atmospheric convection and precipitation processes over the tropical western Pacific ocean.
• Validating satellite microwave radiometer retrievals and algorithms using aircraft-based measurements.
• Investigating the relationship between multi-frequency microwave brightness temperatures and atmospheric state variables during TOGA COARE.

Strengths

• Provides multi-frequency brightness temperature data at four distinct microwave channels.
• Covers a focused 45-day intensive observation period for a major international field campaign.
• Has a defined geographic domain spanning 21 degrees of latitude and 16 degrees of longitude.

Limitations

• The exact row count, file size, and specific column names are not provided by any source.
• Sources conflict on the license ('other-license-specified' vs. 'None') and the last updated date (2026 vs. 1993).
