FIRE Cirrus 1: Surface Radiation Budget Data Over the South Pole

ISCCP analysis of B3 radiance data sampled to 25 km resolution, reported at original pixel resolution with detailed algorithm decision information. The dataset covers the region from 55 to 90 degrees South latitude and 180 degrees West to 180 degrees East longitude. Data was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Modeling polar surface radiation budgets based on high-resolution radiance data.
• Analyzing cloud and atmospheric algorithm performance over the Antarctic region.
• Studying spatial patterns of infrared and visible wavelength radiation in polar projections.
• Validating climate models using detailed, pixel-level satellite-derived data.

Strengths

• Provides data at original pixel resolution (4 km field of view) with detailed algorithm decision information.
• Covers a specific, extensive polar region from 55 to 90 degrees South.
• Includes both visible and infrared wavelength spectral engineering data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
