The Aerosol Limb Imager (ALI) is an optical instrument which measures stratospheric aerosols. These aerosols are of interest to atmospheric science as they have a significant impact on the Earth's climate. ALI has the ability to measure the polarization of atmospheric light over a wide spectral range, which is a novel ability for the measurement ALI uses. We demonstrate and discuss ALI capability and how the polarized information may improve aerosol information for this type of measurement.
