range corrected backscattter signals at 1064 nm (linear scale)

volume linear depolarisation ratio at 532 nm

The depolarization in the orange ellipse indicates a volcanic ash layer.

In the areas within the green ellipses we see ice formation in clouds which is possibly influenced by volcanic ash.

The depolarisation values in yellow to red are typical for cirrus clouds.
