AirMSPI verison 6 ellipsoid-projected georegistered radiance product acquired during the N

July 28 to October 6, 2016, the NASA ORACLES flight campaign collected this AirMSPI Level 1B2 product containing radiometric and polarimetric images of clouds, aerosols, and the Earth's surface. The data includes map-projected radiance, time, and geometry information across eight wavelengths from 355 to 935 nm, with full Stokes parameters for three polarized bands. It was acquired over the South Atlantic Ocean off the coasts of Namibia and Angola, based from Walvis Bay.

Use Cases

• Analyze aerosol properties and cloud interactions based on multi-wavelength radiance and polarization data.
• Develop or validate atmospheric retrieval algorithms based on the Stokes parameters Q and U.
• Study surface reflectance characteristics based on georegistered radiance measurements across eight spectral bands.
• Model radiative transfer in the atmosphere based on concurrent solar and view zenith/azimuth geometry data.

Strengths

• Data covers eight specific wavelengths: 355, 380, 445, 470, 555, 660, 865, and 935 nm.
• Includes full polarimetric information (Stokes Q, U, DOLP, AOLP) for the 470, 660, and 865 nm bands.
• Acquired during a dedicated NASA field campaign (ORACLES) with a defined temporal and geographic scope.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Data is distributed in HDF-EOS-5 format, which may require specialized tools for access and analysis.
