AirMSPI verison 6 terrain-projected georegistered radiance product acquired during the SPEX-PR flight campaign

Metadata Updated: December 6, 2023

AirMSPI_SPEX-PR_Terrain-projected_Georegistered_Radiance_Data is an AirMSPI terrain-projected georegistered radiance product acquired during the SPEX engineering flights + Porter Ranch gas leak overflights (SPEX-PR) 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 SPEX engineering flights + Porter Ranch gas leak overflights (SPEX-PR) flight campaign, which was based out of Armstrong Flight Research Center in Palmdale, CA. The SPEX engineering flights conducted on February 2 through February 5, 2016 focused on the checkout of another polarimeter, SPEX airborne, built by SRON Netherlands Institute for Space Research, with AirMSPI providing validation. On February 9, the ER-2 overflew the Porter Ranch, California natural gas leak with AirMSPI and the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) collecting data.
