Description
AirMSPI Level 1B2 products contain radiometric and polarimetric images of clouds, aerosols, and the Earth's surface. The dataset includes map-projected data at eight wavelengths from 355 to 935 nm, with polarization information for three bands. This release contains all targets acquired during the NASA SEAC4RS flight campaign from August 1 through September 23, 2013, focusing on the United States.
Use Cases
Analyzing aerosol optical properties and cloud phase using Stokes parameters Q and U from the 470, 660, and 865 nm bands.
Studying surface reflectance and atmospheric correction using radiance measurements across eight spectral bands.
Investigating angular scattering signatures of atmospheric constituents using view zenith and view azimuth data.
Validating satellite retrievals of atmospheric composition with high-resolution airborne polarimetric imagery.
Calculating the degree of linear polarization (DOLP) and angle of linear polarization (AOLP) for polarimetric studies.
Strengths
Provides polarimetric data (Stokes Q, U, DOLP, AOLP) for three wavelengths (470, 660, 865 nm), enabling detailed scattering analysis.
Covers a specific, focused campaign period from August 1 to September 23, 2013, ensuring temporal consistency.
Includes data from eight distinct spectral bands (355, 380, 445, 470, 555, 660, 865, 935 nm) for multi-spectral analysis.
Limitations
Key metadata conflicts: row count, size, and specific license are unknown across all platforms.
Dataset is from a single, time-bound campaign in 2013, limiting temporal scope and contemporary relevance.
Data format is HDF-EOS-5, which may require specialized software or libraries for access and processing.
