Between the tropopause height and about 23 km, good agreement is found between the SAGE II 1.02-μm extinction profiles and the lidar profiles, using for the conversion of backscattering into extinction an aerosol model consistent with the SAGE II spectral extinction. The extinction profiles deduced from the limb photographs at 0.44 and 0.375 μm present a good agreement with the SAGE II profiles at 0.453 and 0.385 μm respectively. The size distribution retrieved from the near-infrared polarimetric observations leads to a spectral variation of the extinction in good agreement with SAGE II data in the same altitude range.
