AirMSPI RADEX: Ellipsoid-Projected Radiance Data from 2015 Flight Campaign

AirMSPI Level 1B2 products contain radiometric and polarimetric images of clouds, aerosols, and the Earth's surface. The data includes map-projected radiance, time, and geometry information across 8 wavelengths from 355 to 935 nm, with polarization data for three bands. This release contains all targets from the Radar Definition Experiment (RADEX) flight campaign based in Washington, with data acquired from November 10 through December 13, 2015.

Use Cases

• Analyzing cloud and aerosol properties based on multi-wavelength radiance and polarization data
• Validating new radar instruments for satellite missions based on the co-acquired AirMSPI cloud characterization data
• Studying surface reflectance and atmospheric scattering based on Stokes parameters and geometry angles
• Developing algorithms for polarimetric remote sensing based on degree and angle of linear polarization measurements

Strengths

• Data includes measurements at 8 specific wavelengths: 355, 380, 445, 470, 555, 660, 865, and 935 nm
• Provides polarization information (Stokes Q, U, DOLP, AOLP) for three wavelengths (470, 660, and 865 nm)
• Covers a defined temporal range from November 10 through December 13, 2015

Limitations

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