AirMSPI version 5 terrain-projected georegistered radiance product acquired during the NASA PODEX flight campaign Jan-Feb 2013

AirMSPI_PODEX_Terrain-projected_Georegistered_Radiance_Data are AirMSPI terrain-projected georegistered radiance product acquired during the NASA Polarimeter Definition Experiment (PODEX) flight campaign.

AirMSPI Level 1B2 products contain radiometric and polarimetric images of clouds, aerosols, and the surface of the Earth. In particular, products contain map-projected data at 8 wavelengths: 355, 380, 445, 470, 555, 660, 865, and 935 nm. The data products include radiance, time, solar zenith, solar azimuth, view zenith, and view azimuth for all spectral bands. Wavelengths for which polarization information is available (470, 660, and 865 nm) also include the Stokes parameters Q and U, as well as degree of linear polarization (DOLP) and angle of linear polarization (AOLP). Q, U, and AOLP are reported relative to both the scattering and view meridian planes. Files are distributed in HDF-EOS-5 format.

This release of AirMSPI data contains all targets acquired during the Polarimeter Definition Experiment (PODEX) flight campaign. PODEX was based out of NASA’s Armstrong (formerly Dryden) Flight Research Center in Palmdale, CA, and focused on clouds and aerosols in and around California. AirMSPI data were acquired from January 14 through February 6, 2013.
