CAMEX-3 NAST-I Airborne Radiance Products

CAMEX-3 NAST-I RADIANCE PRODUCTS V1 is a dataset from the NPOESS Atmospheric Sounding Testbed, a suite of airborne infrared and microwave spectrometers flown on NASA's ER-2 aircraft. The data are used to simulate satellite-based radiance measurements for validating instrument specifications and processing techniques for future remote sensors. The dataset is managed by the GHRC_DAAC and has been updated as recently as 2026.

Use Cases

• Simulating satellite radiance measurements using airborne infrared and microwave spectrometer data.
• Validating atmospheric temperature profile retrieval algorithms using brightness temperature data.
• Analyzing cloud properties and atmospheric water vapor profiles from spectral radiance measurements.
• Assessing trace gas concentrations in the atmosphere through infrared spectral analysis.
• Testing data processing techniques for advanced atmospheric remote sensors prior to satellite deployment.

Strengths

• Data originates from a controlled, high-altitude airborne platform (NASA ER-2), providing precise atmospheric measurements.
• The dataset's cross-platform presence on NASA Earthdata and Data.gov signals its established importance for the remote sensing community.
• It supports the validation of future satellite systems, indicating its role in critical risk reduction efforts.

Limitations

• Specific column names, row counts, and dataset size are not documented on any platform.
• There is a conflict in the recorded 'last updated' date between sources (1998 vs. 2026), casting doubt on metadata accuracy.
• The license is inconsistently reported as 'other-license-specified' or 'None', requiring user verification.
