CAMEX-4 ER-2 MAS: Airborne Visible and Infrared Imagery

The dataset contains imagery collected during the CAMEX-4 field campaign. It provides visible and infrared imagery from the MODIS Airborne Simulator (MAS) instrument, calibrated to at-sensor radiance and acquired from a NASA ER-2 high-altitude research aircraft. Associated files include flight line tracks and text files of nadir brightness temperature and radiance for selected bands.

Use Cases

• Analyzing cloud microphysical properties based on calibrated infrared radiance.
• Mapping surface features using high spatial resolution visible and infrared imagery.
• Validating satellite sensor retrievals using coincident airborne spectrometer data.
• Studying atmospheric radiative transfer using nadir brightness temperature profiles.

Strengths

• Data is calibrated to at-sensor radiance, providing a physically consistent measurement foundation.
• Includes multiple associated file types (imagery, browse files, text data) for comprehensive analysis.
• Acquired from a high-altitude platform (NASA ER-2), enabling wide-area, high-resolution coverage.

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable across all sources.
• Sources conflict on the last update date, with one listing 2001 and others listing 2026, creating uncertainty about data currency.
• License is ambiguously specified as 'other-license-specified' without further details.
