The Ground-based Multiangle SpectroPolarimetric Imager (GroundMSPI) was a joint effort between the Jet Propulsion Laboratory and the University of Arizona and the predecessor of MSPI and AirMSPI. The GroundMSPI measures polarized reflectance within the atmosphere that varies in illumination-view geometries. Polarization information is collected at three wavelength bands: 470 nm, 660 nm, and 865 nm. With the results scientists can measure the pBRF within each sampled region by taking the ratio of the region’s polarized radiance to the radiance obtained from a Spectralon panel. Then select the best fit linear slope that compares the pBRFs at the three wavelengths and report the results in histograms to summarize the range of slopes for each region type.
