AirMSPI RADEX: Terrain-Projected Radiance Data for Clouds and Aerosols, 2015

The Radar Definition Experiment (RADEX) flight campaign, based out of Joint Base Lewis-McChord, Washington, collected this airborne remote sensing data. NASA's AirMSPI instrument captured radiometric and polarimetric images of clouds, aerosols, and Earth's surface across 8 wavelengths from 355 to 935 nm. Data includes radiance, time, and geometry parameters, with Stokes parameters for polarized bands, from November 10 to December 13, 2015.

Use Cases

• Characterizing cloud microphysical properties based on multi-wavelength radiance and polarization data.
• Validating satellite-based radar instruments using co-located airborne polarimetric imagery.
• Analyzing aerosol optical properties based on spectral radiance and degree of linear polarization.
• Studying surface reflectance and bidirectional reflectance distribution functions (BRDF) using terrain-projected, georegistered data.

Strengths

• Contains data for 8 specific wavelengths: 355, 380, 445, 470, 555, 660, 865, and 935 nm.
• Includes polarization information (Stokes parameters Q, U, DOLP, AOLP) for the 470, 660, and 865 nm bands.
• Data is terrain-projected and georegistered, providing a map-ready spatial reference.

Limitations

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