Simulated radiances (lines) compared to measurements (dots) over Pacific Ocean, close to Mexico. The upper curves represent the radiances at 865 (red) and 670 nm (blue). The curves at the bottom correspond to the polarized radiances. Note that to point out the aerosol contributions, the molecular signal has been removed. On this case, the spectral effect is rather weak, which indicates large particles. Rainbows can be observed at a scattering angle 145°, specially for polarized radiances, which corresponds to spherical particles.

Same that previous picture but for measurements over Indian Ocean, close to Madagascar. Note a significant spectral effect of the radiances, associated to small particles that generated large polarized radiances.
