Figure Caption Spectral smoke aerosol optical properties as a function of aerosol optical thickness at 500 nm (ta) calculated from three years of data collected during the dry season in Amazonia. The red curves represent the single scattering albedo (w0), the green curves represent the asymmetry factor (g) and the blue curves represent the extinction efficiency (Qe). Dotted curves refer to ta smaller than 0.20, dashed curves refer to ta between 0.20 and 1.60 and solid curves refer to ta greater than 1.60.
