Abstract

Linear polarization of the clear daytime sky has often been measured as a spectrally integrated or quasi-monochromatic variable, but seldom as a spectral one. So we use a hyperspectral imaging system to measure skylight polarization at high spectral and angular resolutions for clear and hazy skies at our coastal site. The resulting polarization maps and spectra exhibit both commonalities and differences that seem unexplained by an existing polarized radiative transfer model. Comparing the measured polarization spectra with those predicted by aerosol single scattering suggests some basic verisimilitude tests for improving such models.

  45. Data from ϕrel∼270° (Fig. 4) are compared with that from ϕrel=90° (Fig. 1) because both Ψ and compass azimuth ϕ are nearly equal in the two scenes. Having equivalent ϕ at a given h0 reduces the PLλ effects of spatial changes in land and water spectral reflectances near our site.
