AirMSPI PODEX Airborne Polarimetric Radiance Data for Clouds and Aerosols

AirMSPI terrain-projected georegistered radiance data contains radiometric and polarimetric images from the NASA PODEX flight campaign. The dataset provides map-projected measurements at eight wavelengths from 355 to 935 nm, including Stokes parameters for three bands. Data was acquired by NASA's Airborne Multiangle SpectroPolarimetric Imager over California from January 14 to February 6, 2013.

Use Cases

• Analyzing aerosol optical properties using radiance and degree of linear polarization (DOLP) columns.
• Studying cloud phase and particle size distribution with multi-wavelength (355-935 nm) radiance measurements.
• Validating satellite polarimeter algorithms with airborne Stokes parameters Q and U relative to meridian planes.
• Investigating surface-atmosphere interactions using georegistered radiance data over terrestrial targets.
• Assessing polarimetric data quality by comparing angle of linear polarization (AOLP) across scattering and view planes.

Strengths

• Provides polarimetric data for three specific wavelengths (470, 660, 865 nm) with Stokes parameters Q and U.
• Contains a defined temporal range of observations from a focused campaign (January 14 - February 6, 2013).
• Includes georegistered, map-projected data across eight spectral bands from ultraviolet to near-infrared.

Limitations
